Google unveils two new TPUs designed for the "agentic era"

Most of the companies that have fully committed to building AI models are gobbling up every Nvidia AI accelerator they can get, but Google has taken a different approach. Most of its cloud AI infrastructure is based on its line of custom Tensor processing units (TPUs). After announcing the seventh-gen Ironwood TPU in 2025, the company has moved on to the eighth-gen version, but it’s not just a faster iteration of the same chip. The new TPUs come in two flavors, providing Google and its customers with an AI platform that is faster and more efficient, the company says. Google is pushing the idea that the “agent era” is fundamentally different from the AI systems that came before, necessitating a new approach to the hardware. So engineers have devised the TPU8t (for training) and the TPU 8i (for inference). Before…

Anthropic gets $5B investment from Amazon, will use it to buy Amazon chips

Amazon has significantly boosted its multibillion-dollar bet on Claude developer Anthropic by investing an additional $5 billion—enabling Anthropic to eventually secure up to 5 gigawatts’ worth of AI chips from Amazon to help train and run its popular Claude AI models. Amazon is already one of Anthropic’s largest investors, having previously invested $8 billion in the AI startup. The latest move brings Amazon’s immediate investment up to $13 billion, and the companies have agreed to the possibility of Amazon committing another $20 billion in the future if the partnership achieves certain commercial milestones, according to Wall Street Journal reporting. The large cash infusion and prospect of obtaining more computing resources come at a crucial time for Anthropic, given the massive surge in paid subscriptions for Claude-related services early this year. That demand spike and strain on the existing cloud compute…

4/3/2026 Scaling and Optimizing Frontier Model Training

On this page How Fireworks scales frontier model training and offers the broadest set of fine-tunable MoE models on any platform. Training trillion-parameter Mixture-of-Experts (MoE) models has historically been bottlenecked by memory walls and complex cluster orchestration. Earlier this month, Cursor released Composer 2 — a frontier coding model that tops CursorBench at 61.3, SWE-bench Multilingual at 73.7, and Terminal-Bench at 61.7. Fireworks powers the Reinforcement Learning (RL) inference infrastructure behind it, proving that these bottlenecks can be overcome at scale. We have written about delta-compressed weight sync and multi-region rollout fleets, and about why numerical parity between training and inference is especially hard for MoE models. Those posts cover the inference half of the RL loop — rollouts, weight transfer, and numerical alignment. This post covers the last missing piece: the trainer itself. Our Training SDK provides the model…

1/31/2025 Distillation with Reasoning: Can DeepSeek R1 Teach Better Than Humans?

The recent release of DeepSeek R1 has taken the AI community by storm, offering performance on par with leading frontier models—such as OpenAI’s o1—at a fraction of the cost. Still, R1 can be expensive for use cases with high traffic or low latency requirements. DeepSeek R1’s strength lies in its explicit step-by-step reasoning. Before generating a final answer, it creates an internal “chain of thought” (CoT) to systematically reason through each problem. This process is a form of test-time computation, allowing the model to dynamically allocate more compute to complex problems. However, these extended reasoning sequences typically increase inference cost. Distillation is a method for transferring knowledge from a large, more powerful teacher model to a smaller, more cost-effective student model. According to the DeepSeek R1 paper, R1 is highly effective in this teacher role. Its detailed CoT sequences guide…

Waypoint-1.5: Higher-Fidelity Interactive Worlds for Everyday GPUs

Waypoint-1.5: Higher-Fidelity Interactive Worlds for Everyday GPUs Try it What is Waypoint-1.5? Waypoint-1.5 is Overworld’s next real-time video world model, built to bring interactive generative worlds to the hardware people actually own. The first release of Waypoint showed that real-time generative worlds were possible. It proved that interactive world models could be more than passive video demos, and that locally runnable systems could begin to close the gap between generating a world and actually stepping into one. Waypoint-1.5 builds directly on that foundation. This release improves visual fidelity, expands the range of hardware that can run the model locally, and takes another step toward interactive world simulation without datacenter-scale compute. On desktop hardware including RTX 3090 through 5090, Waypoint-1.5 can generate real-time environments at up to 720p and 60 FPS. This release also introduces a 360p tier designed to run…

Liberate your OpenClaw

Liberate your OpenClaw 🦀 If you've been cut off and your OpenClaw, Pi, or Open Code agents need resuscitation, you can move them to open models in two ways: - Use an open model served through Hugging Face Inference Providers. - Run a fully local open model on your own hardware. The hosted route is the fastest way back to a capable agent. The local route is the right fit if you want privacy, zero API costs, and full control. To do so, just tell your claude code, your cursor or your favorite agent: help me move my OpenClaw agents to Hugging Face models, and link this page. Hugging Face Inference Providers Hugging Face inference providers is an open platform that routes to providers of open source models. It’s the right choice if you want the best models or you…

PRX Part 3 — Training a Text-to-Image Model in 24h!

PRX Part 3 — Training a Text-to-Image Model in 24h! Introduction Welcome back 👋 In the last two posts (Part 1 and Part 2), we explored a wide range of architectural and training tricks for diffusion models. We tried to evaluate each idea in isolation, measuring throughput, convergence speed, and final image quality, and tried to understand what actually moves the needle. In this post, we want to answer a much more practical question: What happens when we combine all the tricks that worked? Instead of optimizing one dimension at a time, we’ll stack the most promising ingredients together and see how far we can push performance under a strict compute budget. To make things concrete, we’re doing a 24-hour speedrun: - 32 H200 - ~$1500 total compute budget (2$/hour/GPU) This is very far from the early diffusion days, where…

Mixture of Experts (MoEs) in Transformers

Mixture of Experts (MoEs) in Transformers Introduction Over the past few years, scaling dense language models has driven most progress in LLMs. From early models like the original ULMFiT (~30M parameters) or GPT-2 (1.5B parameters, which at the time was considered "too dangerous to release" 🧌), and eventually to today’s hundred-billion–parameter systems, the recipe was simple: More data + more parameters gives better performance. Scaling laws reinforced this trend, but dense scaling has practical limits: - Training becomes increasingly expensive. - Inference latency grows. - Deployment requires significant memory and hardware. This is where Mixture of Experts (MoEs) enter the picture. If you're already familiar with MoEs and want to jump straight into the engineering work done in transformers, you can head directly to Transformers and MoEs. From Dense to Sparse: What Are MoEs? A Mixture of Experts model keeps…

We Got Claude to Build CUDA Kernels and teach open models!

We got Claude to teach open models how to write CUDA kernels! - You can take Opus 4.5 or other SOTA models and tackle the hardest problems out there. - You can take models that run on your laptop and upskill them to harder problems. In this blog post, we’ll show you how to take on the latter. This blog post walks through the process of using a new tool, upskill , to generate and evaluate agent skills with large models and use them with smaller models. We will benchmark upskill on the task of writing CUDA kernels for diffusers models, but the process is generally useful for cutting costs, or using smaller models on hard and domain-specific problems. What are agent skills? In case you missed it, agent skills are taking the coding agent game by storm. In fact,…

Differential Transformer V2

Differential Transformer V2 Notion Link (for better readability) Code We compare DIFF V2 with DIFF V1 below: (For simplicity, we omit the batch dimension and assume that both the input and output of the following flash_attn_func are three-dimensional tensors (tokens, heads, head dimension) . Heads belonging to the same GQA group are arranged contiguously in the output) Note DIFF V2 subtracts two heads that are in the same GQA group, which means they share the same key and value.

Streaming datasets: 100x More Efficient

Streaming datasets: 100x More Efficient TLDR We boosted load_dataset('dataset', streaming=True) , streaming datasets without downloading them with one line of code!Start training on multi-TB datasets immediately, without complex setups, downloading, no "disk out of space", or 429 “stop requesting!” errors. It's super fast! Outrunning our local SSDs when training on 64xH100 with 256 workers downloading data. We've improved streaming to have 100x fewer requests, → 10× faster data resolution → 2x sample/sec, → 0 worker crashes at 256 concurrent workers. Loading data, especially at the terabyte scale, is a major pain in any machine learning workflow. We suffered this while training SmolLM3, at one point we had to wait 3 hours before each run to download enough data. Streaming has always been possible in the datasets library, but large scale training with massive datasets remained a challenge. That changes today…

Get your VLM running in 3 simple steps on Intel CPUs

Get your VLM running in 3 simple steps on Intel CPUs While running AI models on your own device can be difficult as these models are often computationally demanding, it also offers significant benefits: including improved privacy since your data stays on your machine, and enhanced speed and reliability because you're not dependent on an internet connection or external servers. This is where tools like Optimum Intel and OpenVINO come in, along with a small, efficient model like SmolVLM. In this blog post, we'll walk you through three easy steps to get a VLM running locally, with no expensive hardware or GPUs required (though you can run all the code samples from this blog post on Intel GPUs). Deploy your model with Optimum Small models like SmolVLM are built for low-resource consumption, but they can be further optimized. In this…

SOTA OCR with Core ML and dots.ocr

SOTA OCR with Core ML and dots.ocr Enter the Neural Engine, Apple's custom AI accelerator that has shipped with every Apple device since 2017. This accelerator is designed for high performance whilst sipping battery power. Some of our testing has found the Neural Engine to be 12x more power efficient than CPU, and 4x more power efficient than GPU. Whilst this all sounds very appealing, unfortunately the Neural Engine is only accessible through Core ML, Apple's closed source ML framework. Furthermore, even just converting a model from PyTorch to Core ML can present some challenges, and without a preconverted model or some knowledge of the sharp edges it can be arduous for developers. Luckily, Apple also offers MLX, a more modern and flexible ML framework that targets the GPU (not the Neural Engine), and can be used in conjunction with…

We want to double down on the use cases that provide most benefits to the community, and lay out the foundations for the future. Spoiler alert: after this release, we’ll focus a lot on MLX and agentic use cases 🚀 What is swift-transformers swift-transformers is a Swift library that aims to reduce the friction for developers that want to work with local models on Apple Silicon platforms, including iPhones. It includes the missing pieces that are not provided by Core ML or MLX alone, but…

Make your ZeroGPU Spaces go brrr with ahead-of-time compilation

Make your ZeroGPU Spaces go brrr with ahead-of-time compilation This is where PyTorch ahead-of-time (AoT) compilation comes in. Instead of compiling models on the fly (which doesn’t play nicely with ZeroGPU’s short-lived processes), AoT lets you optimize once and reload instantly. The result: snappier demos and a smoother experience, with speedups ranging from 1.3×–1.8× on models like Flux, Wan, and LTX 🔥 In this post, we’ll show how to wire up Ahead-of-Time (AoT) compilation in ZeroGPU Spaces. We'll explore advanced tricks like FP8 quantization and dynamic shapes, and share working demos you can try right away.

Android and cross-platform developers—whether first- or third-party—gain instant access to KleidiAI AI performance optimizations via ExecuTorch and XNNPack. The result? Faster model startups, lower latency, leaner memory footprints—and no integration hurdles. What previously required custom tuning…

(LoRA) Fine-Tuning FLUX.1-dev on Consumer Hardware

(LoRA) Fine-Tuning FLUX.1-dev on Consumer Hardware In our previous post, Exploring Quantization Backends in Diffusers, we dived into how various quantization techniques can shrink diffusion models like FLUX.1-dev, making them significantly more accessible for inference without drastically compromising performance. We saw how bitsandbytes , torchao , and others reduce memory footprints for generating images. Performing inference is cool, but to make these models truly our own, we also need to be able to fine-tune them. Therefore, in this post, we tackle efficient fine-tuning of these models with peak memory use under ~10 GB of VRAM on a single GPU. This post will guide you through fine-tuning FLUX.1-dev using QLoRA with the diffusers library. We'll showcase results from an NVIDIA RTX 4090. We'll also highlight how FP8 training with torchao can further optimize speed on compatible hardware. Table of Contents -…

How Long Prompts Block Other Requests - Optimizing LLM Performance

How Long Prompts Block Other Requests - Optimizing LLM Performance The Simpler Challenge: Long Prompts Block the Queue Since individual decode steps are not compute-intensive, one can increase throughput by batching decodes of multiple requests. For prefill, however, this approach does not work. Because of the parallelized processing of all prompt tokens, a single prefill step can already saturate GPU utilization. Consequently, in the default chunked-prefill strategy of vLLM, each prefill chunk contains only prompt tokens of a single request. The next request in line has to wait until the previous prefill phase has been finished before its own prefill phase can start. This sequential scheduling of prefill chunks for different requests poses a challenge: whenever a request with a very long prompt is scheduled for prefill, any subsequent request has to wait for the duration of the long prefill…

No GPU left behind: Unlocking Efficiency with Co-located vLLM in TRL

No GPU left behind: Unlocking Efficiency with Co-located vLLM in TRL 🚀 Introduction TRL supports training LLMs using GRPO, an online learning algorithm recently introduced in the DeepSeekMath paper. In GRPO, the model learns from its own outputs: it generates responses during training, receives feedback, and uses that feedback to improve itself over time. This makes generation a critical step in the training loop — and also a major bottleneck. To speed up generation, TRL integrates with vLLM. This combination lets you train powerful models more efficiently in GRPO setup. However, there’s a catch. 🧨 The Problem Before TRL v0.18.0, vLLM was only supported in server mode, running as a separate process on different GPUs from the training job. It communicated with the training script over HTTP, which made the setup modular and easy to use — but also introduced…

Prefill and Decode for Concurrent Requests - Optimizing LLM Performance

Prefill and Decode for Concurrent Requests - Optimizing LLM Performance At TNG, we are self-hosting numerous Large Language Models on our cluster of 24 H100 GPUs. It supports 50 different applications, handles over 5,000 inferences per hour, and generates more than ten million tokens every day. The Two Stages of Token Generation: Prefill and Decode Most LLMs generate text token by token, which guarantees that every new token is computed based on all preceding tokens (this model property is called auto-regressive). The first output token depends on all prompt tokens, but the second output token already depends on all prompt tokens plus the first output token, and so on. As a consequence, token generation cannot be parallelized at the level of an individual request. In LLMs with attention mechanisms, computing a new token requires calculating key, value, and query vectors…

Efficient Request Queueing – Optimizing LLM Performance

Efficient Request Queueing – Optimizing LLM Performance Starting Point: A Bare Inference Engine An inference engine like vLLM or HuggingFace TGI consists of - a worker that does the actual work of calculating the next token in a request - a queue to which requests are added when they first arrive - a scheduler that takes requests from the queue and moves them to the worker Why do we need a queue here? Because calculations on the GPU are more performant and resource-efficient when they are done batch-wise instead of isolated for individual requests. This backend queue allows the scheduler to pick multiple requests and put them on the same batch to be processed. Note that typically each inference engine serves only a single model, and we have multiple deployments running for different models in parallel. Problem: "Power Users" Can…

Visualize and understand GPU memory in PyTorch RuntimeError: CUDA out of memory. Tried to allocate 20.00 MiB (GPU 0; 7.93 GiB total capacity; 6.00 GiB already allocated; 14.88 MiB free; 6.00 GiB reserved in total by PyTorch) While it's easy to see that GPU memory is full, understanding why and how to fix it can be more challenging. In this tutorial, we'll go step by step on how to visualize and understand GPU memory usage in PyTorch during training. We’ll also see how to estimate memory requirements and optimize GPU memory usage. 🔎 The PyTorch visualizer PyTorch provides a handy tool for visualizing GPU memory usage: import torch from torch import nn # Start recording memory snapshot history torch.cuda.memory._record_memory_history(max_entries=100000) model = nn.Linear(10_000, 50_000, device ="cuda") for _ in range(3): inputs = torch.randn(5_000, 10_000, device="cuda") outputs = model(inputs) # Dump memory…

Scaling the AI-Ready Data Center with NVIDIA RTX PRO 4500 Blackwell Server Edition and NVIDIA vGPU 20

AI integration is redefining mainstream enterprise applications, from productivity software like Microsoft Office to more complex design and engineering tools. This shift requires the modern data center to move beyond single-purpose silos. For developers, gaining access to dedicated GPU compute can often be a bottleneck. Virtual machines (VMs) solve part of this challenge by providing secure, isolated, and scalable environments tailored to specific project needs. However, dedicating an entire physical GPU to a single VM is highly inefficient for mixed or lightweight workloads. This is where NVIDIA Multi-Instance GPU (MIG) technology becomes essential. With MIG, a single physical GPU is partitioned at the hardware level into multiple fully independent instances, each with guaranteed memory, cache, and compute cores. For a development team, this ensures predictable, uncompromising Quality of Service (QoS). This means that multiple developers can simultaneously train AI models,…

This applies to both single-GPU and multi-GPU systems alike. One of the tools you can use to understand the memory characteristics of your GPU system is NVIDIA NVbandwidth. In this blog post, we’ll explore what NVbandwidth is, how it works, its key features, and how you can use it to test and evaluate your own NVIDIA GPU systems. This post is intended for CUDA developers, system architects, and ML infrastructure engineers who need to measure and validate GPU interconnect performance. What is NVbandwidth? NVbandwidth is a CUDA-based tool that measures bandwidth and latency for various memory copy patterns across different links using either copy engine (CE) or kernel copy methods. It reports the current measured bandwidth…

NVIDIA Ising Introduces AI-Powered Workflows to Build Fault-Tolerant Quantum Systems

NVIDIA Ising is the world’s first family of open AI models for building quantum processors, launching with two model domains: Ising Calibration and Ising Decoding. Both target the fundamental challenge in quantum computing—qubits are inherently noisy. The best quantum processors make an error roughly once in every thousand operations. To become useful accelerators for scientific and enterprise problems, error rates must drop to one in a trillion or better. AI is the most promising path to closing that gap at scale. Calibration is the process of understanding the noise in each quantum processor and tuning it to achieve the best possible performance. Calibration minimizes error, but because of noise in quantum systems, errors must be corrected in real time by a classical computer, faster than they accumulate. This process is called quantum error correction decoding. Both calibration and decoding are…

Running Large-Scale GPU Workloads on Kubernetes with Slurm

Slurm is an open source cluster management and job scheduling system for Linux. It manages job scheduling for over 65% of TOP500 systems. Most organizations running large-scale AI training have years of investment in Slurm job scripts, fair-share policies, and accounting workflows. The challenge is getting Slurm scheduling capabilities onto Kubernetes—the standard platform for managing GPU infrastructure at scale—without maintaining two separate environments. Slinky, an open source project developed by SchedMD (now part of NVIDIA), takes two approaches to this integration: - slurm-bridge brings Slurm scheduling to native Kubernetes workloads, allowing Slurm to act as a Kubernetes scheduler for pods - slurm-operator runs full Slurm clusters on Kubernetes infrastructure, managing the complete lifecycle of Slurm daemons as pods This post focuses on the slurm-operator, which is how NVIDIA runs Slurm on Kubernetes for large-scale GPU training clusters. It walks through…

Running AI Workloads on Rack-Scale Supercomputers: From Hardware to Topology-Aware Scheduling

The NVIDIA GB200 NVL72 and NVIDIA GB300 NVL72 systems, featuring NVIDIA Blackwell architecture, are rack-scale supercomputers. They’re designed with 18 tightly coupled compute trays, massive GPU fabrics, and high-bandwidth networking packaged as a unit. For AI architects and HPC platform operators, the challenge isn’t just racking and stacking hardware—it’s turning infrastructure into safe, performant, and easy-to-use resources for end users. The mismatch between rack-scale hardware topology and scheduler abstractions is where most of the operational complexity lives. Left unaddressed, schedulers operate on a flat pool of GPUs and nodes, overlooking the system’s hierarchical and topology-sensitive design. This is the gap that a validated software stack, such as NVIDIA Mission Control, is designed to bridge. Mission Control provides rack-scale control planes for NVIDIA Grace Blackwell NVL72 systems. With a native understanding of NVIDIA NVLink and NVIDIA IMEX domains, it integrates with…

Accelerating Vision AI Pipelines with Batch Mode VC-6 and NVIDIA Nsight

In vision AI systems, model throughput continues to improve. The surrounding pipeline stages must keep pace, including decode, preprocessing, and GPU scheduling. In the previous post, Build High-Performance Vision AI Pipelines with NVIDIA CUDA-Accelerated VC-6, this was described as the data-to-tensor gap—a performance mismatch between AI pipeline stages. The SMPTE VC-6 (ST 2117-1) codec addresses this gap through a hierarchical, tile-based architecture. Images are encoded as progressively refinable Levels of Quality (LoQs), each adding incremental detail. This enables selective retrieval and decoding of only the required resolution, region of interest, or color plane, with random access to independently decodable frames. Pipelines can retrieve and decode only what the model needs. However, efficient single-image execution does not automatically translate to efficient scaling. As batch sizes grow, the bottleneck shifts from single-image kernel efficiency to workload orchestration, launch cadence, and GPU occupancy.…

CUDA Tile Programming Now Available for BASIC!

Note: CUDA Tile Programming in BASIC is an April Fools’ joke, but it’s also real and actually works, demonstrating the flexibility of CUDA. CUDA 13.1 introduced CUDA Tile, a next generation tile-based GPU programming paradigm designed to make fine-grained parallelism more accessible and flexible. One of its key strengths is language openness: any programming language can target CUDA Tile, enabling developers to bring tile-based GPU acceleration into a wide range of ecosystems. In response to overwhelming demand from seasoned developers everywhere, we’re releasing cuTile BASIC for GPUs, bringing CUDA Tile programming to this long-overlooked language. What is cuTile BASIC? cuTile BASIC is an expression of the CUDA Tile programming model in BASIC, built on top of the CUDA Tile IR specification. It enables you to write tile kernels in BASIC using a tile-based model, which is a natural fit for…

Accelerate Token Production in AI Factories Using Unified Services and Real-Time AI

In today’s AI factory environment, performance is not theoretical. It is economic, competitive, and existential. A 1% drop in usable GPU time can mean millions of tokens lost per hour. Minutes of congestion can cascade into hours of recovery. A rack-level power oversubscription can lead to stranded power and reduced tokens per watt, silently eroding factory output at scale. As AI factories scale to thousands of GPUs running diverse mission critical workloads, the cost of unpredictable congestion, power constraints, long-tail latency, and limited visibility grows exponentially. Operations teams and administrators need more than dashboards. They need flexibility and foresight. NVIDIA launched NVIDIA Mission Control as an integrated software stack for AI factories built on NVIDIA reference architectures, codifying NVIDIA best practices with a unified control plane. Mission Control version 3.0 expands further, introducing architectural flexibility, multi-org isolation, intelligent power orchestration…

Stream High-Fidelity Spatial Computing Content to Any Device with NVIDIA CloudXR 6.0

Spatial computing is moving from visualization to active collaboration, adding increasingly more GPU demands on XR hardware to render photorealistic, physics-accurate, high-fidelity spatial content in real time. Meanwhile, developers have had to maintain separate codebases for every platform, each with different toolchains, SDKs, and streaming protocols. At NVIDIA GTC 2026, NVIDIA CloudXR 6.0 introduced a universal OpenXR-based streaming runtime that works across headsets, operating systems, and browsers—including native visionOS integration.

Maximize AI Infrastructure Throughput by Consolidating Underutilized GPU Workloads

In production Kubernetes environments, the difference between model requirements and GPU size creates inefficiencies. Lightweight automatic speech recognition (ASR) or text-to-speech (TTS) models may require only 10 GB of VRAM, yet occupy an entire GPU in standard Kubernetes deployments. Because the scheduler maps a model to one or more GPUs and can’t easily share across GPUs across models, expensive compute resources often remain underutilized. Solving this isn’t just about cost reduction—it’s about optimizing cluster density to serve more concurrent users on the same world-class hardware. This guide details how to implement and benchmark GPU partitioning strategies, specifically NVIDIA Multi-Instance GPU (MIG) and time-slicing to fully use compute resources. Using a production-grade voice AI pipeline as our testbed, we show how to combine models to maximize infrastructure ROI while maintaining >99% reliability and strict latency guarantees. Addressing GPU resource fragmentation By…

How Centralized Radar Processing on NVIDIA DRIVE Enables Safer, Smarter Level 4 Autonomy

In the current state of automotive radar, machine learning engineers can’t work with camera-equivalent raw RGB images. Instead, they work with the output of radar constant false alarm rate (CFAR), which is similar to computer vision (CV) edge detections. The communications and compute architectures haven’t kept pace with trends in AI and the needs of Level 4 autonomy, despite radar being a staple of vehicle‑level sensing for years. The real 3D/4D “image” signal is instead processed inside the edge device. The radar outputs objects, or in some cases point clouds, which is similar to a camera outputting a classical CV Canny edge‑detection image. Centralized radar processing on NVIDIA DRIVE changes this model: Raw analog‑to‑digital converter (ADC) data moves into a centralized compute platform. From there, a software-defined pipeline accelerated by dedicated NVIDIA Programmable Vision Accelerator (PVA) hardware handles everything from…

Inside NVIDIA Groq 3 LPX: The Low-Latency Inference Accelerator for the NVIDIA Vera Rubin Platform

NVIDIA Groq 3 LPX is a new rack-scale inference accelerator for the NVIDIA Vera Rubin platform, designed for the low-latency and large-context demands of agentic systems. Co-designed with the NVIDIA Vera Rubin NVL72, LPX equips the AI factory with an engine optimized for fast, predictable token generation, while Vera Rubin NVL72 remains the flexible, general-purpose workhorse for training and inference, delivering high throughput across prefill and decode, including long-context processing, decode attention, and high-concurrency serving at scale. This combination matters because the agentic future demands a new category of inference. As generation speeds approach 1,000 tokens per second per user, models move beyond conversation-speed interaction toward speed of thought computing. At that rate, AI systems can reason, simulate, and respond continuously, enabling experiences that feel less like turn-based chat and more like real-time collaboration. This shift also raises the ceiling…

Validate Kubernetes for GPU Infrastructure with Layered, Reproducible Recipes

This post explores the CUDA 13.2 release, which boosts developer productivity with a variety of new Python additions, including profiling in CUDA Python and debugging Numba kernels. The math libraries provide expanded support for high-performance emulated libraries, and CUDA Core Compute Libraries (CCCL) continue to add both performance and feature improvements, providing C++ developers with a high-performance, modern interface to GPU programming. cuTile Python cuTile…

Enhancing Distributed Inference Performance with the NVIDIA Inference Transfer Library

Deploying large language models (LLMs) requires large-scale distributed inference, which spreads model computation and request handling across many GPUs and nodes to scale to more users while reducing latency. Distributed inference frameworks use techniques such as disaggregated serving, KV cache loading, and wide expert parallelism. In disaggregated serving environments, prefill and decode phases are run on separate GPUs, requiring efficient KV cache transfers between them. Low-latency and high-throughput communication to move these KV caches are critical to gain benefits from disaggregated serving. In KV cache loading, storage is used to help with growing KV caches in multiturn and agentic AI workloads such as coding assistants and reasoning. For the case of long context KV, the previous results can be loaded from local SSDs and remote storage, instead of recomputing them as prefill. This is one example that explains why storage…

Controlling Floating-Point Determinism in NVIDIA CCCL

A computation is considered deterministic if multiple runs with the same input data produce the same bitwise result. While this may seem like a simple property to guarantee, it can be difficult to achieve in practice, especially in parallel programming and floating-point arithmetic. This is because floating-point addition and multiplication aren’t strictly associative—that is, (a + b) + c may not equal a + (b + c)—due to rounding that occurs when intermediate results are stored with finite precision. With NVIDIA CUDA Core Compute Libraries (CCCL) 3.1, CUB—a low-level CUDA library for speed-of-light parallel device algorithms—added a new single-phase API that accepts an execution environment, enabling users to customize algorithm behavior. We can use this environment to configure the reduce algorithm’s determinism property. This can only be done through the new single-phase API, since the two-phase API doesn’t accept an…

cuTile.jl Brings NVIDIA CUDA Tile-Based Programming to Julia

NVIDIA CUDA Tile is one of the most significant additions to NVIDIA CUDA programming and unlocks automatic access to tensor cores and other specialized hardware. Earlier this year, NVIDIA released cuTile for Python, giving Python developers a natural way to write high-performance GPU kernels. Now, the same programming model is available in Julia through cuTile.jl. In this blog post, we’ll explore how cuTile.jl simplifies the development of high-performance CUDA kernels, demonstrate its idiomatic Julia syntax, and discuss its performance parity with the existing cuTile Python implementation. What is tile-based GPU programming? Traditional GPU programming with CUDA requires developers to think about threads, warps, and memory hierarchies. While powerful, this approach requires the programmer to map algorithms onto hardware efficiently. With CUDA Tile, developers describe operations on tiles of data, and the compiler handles the mapping to hardware. Consider vector addition.…

Maximizing GPU Utilization with NVIDIA Run:ai and NVIDIA NIM

Organizations deploying LLMs are challenged by inference workloads with different resource requirements. A small embedding model might use only a few gigabytes of GPU memory, while a 70B+ parameter LLM could require multiple GPUs. This diversity often leads to low average GPU utilization, high compute costs, and unpredictable latency. The problem isn’t just about packing more workloads onto GPUs but about scheduling them intelligently. Without orchestration that understands inference workload patterns, organizations face a choice between overprovisioning (wasting resources) and underprovisioning (degrading performance). This blog post covers: - The inference utilization problem: Why traditional scheduling underutilizes GPU resources. - How NVIDIA NIM delivers production inference: The role of containerized microservices in standardizing model deployment. - NVIDIA Run:ai’s intelligent scheduling strategies: Four key capabilities that enhance performance (lower latency, increase TPS/GPU) while increasing GPU utilization and reducing compute costs. - Benchmarking…

Making Softmax More Efficient with NVIDIA Blackwell Ultra

LLM context lengths are exploding, and architectures are moving toward complex attention schemes like Multi-Head Latent Attention (MLA) and Grouped Query Attention (GQA). As a result, AI ”speed of thought” is increasingly governed not by the massive throughput of matrix multiplications, but by the transcendental math of the softmax function. Transcendentals refer to functions that cannot be expressed as the root of a polynomial equation with rational coefficients. Subsequently, they “transcend” basic algebraic operations like addition and multiplication—the exact operations Tensor Cores excel at. In the specific context of softmax, the most computationally expensive of these transcendentals is the natural exponential function that is executed on Special Function Units (SFUs). In NVIDIA assembly instructions (SASS), this function is invoked via the MUFU.EX2 instruction. This architectural split creates a softmax bottleneck within the attention block, when powerful matrix engines are forced…

Accelerating Data Processing with NVIDIA Multi-Instance GPU and Locality Domains

NVIDIA flagship data center GPUs in the NVIDIA Ampere, NVIDIA Hopper, and NVIDIA Blackwell families all feature non-uniform memory access (NUMA) behaviors, but expose a single memory space. Most programs therefore do not have an issue with memory non-uniformity. However, as bandwidth increases in newer generation GPUs, there are significant performance and power gains to be had when taking into consideration compute and data locality. This post first analyzes the memory hierarchy of the NVIDIA GPUs, discussing the power and performance impacts of data transfer over die-to-die link. It then reviews how to use NVIDIA Multi-Instance GPU (MIG) mode to achieve data localization. Finally, it presents results for running MIG mode versus unlocalized for the Wilson-Dslash stencil operator use case. Note: The techniques described in this post are exploratory, and the field is evolving quickly. New developments may supersede what…

Ensuring Balanced GPU Allocation in Kubernetes Clusters with Time-Based Fairshare

NVIDIA Run:ai v2.24 introduces time-based fairshare, a new scheduling mode that brings fair-share scheduling with time awareness for over-quota resources to Kubernetes clusters. This capability, built on the open source KAI Scheduler that powers NVIDIA Run:ai, addresses a long-standing challenge in shared GPU infrastructure. Consider two teams with equal priority sharing a cluster. Team A continuously submits smaller jobs, while Team B needs to run a larger job that requires more resources. Every time resources free up, the smaller jobs from Team A fit immediately and get scheduled. The larger job from Team B continues to wait for enough resources to become available. Before that happens, the next small job from Team A claims the freed capacity. The result: although both teams have identical priority and entitlements, Team A runs job after job while the job from Team B sits…

Accelerating Diffusion Models with an Open, Plug-and-Play Offering

Recent advances in large-scale diffusion models have revolutionized generative AI across multiple domains, from image synthesis to audio generation, 3D asset creation, molecular design, and beyond. These models have demonstrated unprecedented capabilities in producing high-quality, diverse outputs across various conditional generation tasks. Despite these successes, sampling inefficiency remains a fundamental bottleneck. Standard diffusion models require tens to hundreds of iterative denoising steps, leading to high inference latency and substantial computational cost. This limits practical deployment in interactive applications, edge devices, and large-scale production systems. Video generation faces an especially critical challenge. Open source models such as NVIDIA Cosmos—along with commercial text-to-video (T2V) systems —have shown remarkable text-to-video capabilities. However, video diffusion models are orders of magnitude more computationally demanding due to the temporal dimension. Generating a single video can take minutes to hours, making real-time video generation, interactive editing, and…

Adaptive Inference in NVIDIA TensorRT for RTX Enables Automatic Optimization

Deploying AI applications across diverse consumer hardware has traditionally forced a trade-off. You can optimize for specific GPU configurations and achieve peak performance at the cost of portability. Alternatively, you can build generic, portable engines and leave performance on the table. Bridging this gap often requires manual tuning, multiple build targets, or accepting compromises. NVIDIA TensorRT for RTX seeks to eliminate this trade-off. At under 200 MB, this lean inference library provides a Just-In-Time (JIT) optimizer that compiles engines in under 30 seconds. This makes it ideal for real-time, responsive AI applications on consumer-grade devices. TensorRT for RTX introduces adaptive inference—engines that optimize automatically at runtime for your specific system, progressively improving compilation and inference performance as your application runs. No manual tuning, no multiple build targets, no intervention required. Build a lightweight, portable engine once, deploy it anywhere, and…

Scaling NVFP4 Inference for FLUX.2 on NVIDIA Blackwell Data Center GPUs

In 2025, NVIDIA partnered with Black Forest Labs (BFL) to optimize the FLUX.1 text-to-image model series, unlocking FP4 image generation performance on NVIDIA Blackwell GeForce RTX 50 Series GPUs. As a natural extension of the latent diffusion model, FLUX.1 Kontext [dev] proved that in-context learning is a feasible technique for visual-generation models, not just large language models (LLMs). To make this experience more widely accessible, NVIDIA collaborated with BFL to enable a near real-time editing experience using low-precision quantization. FLUX.2 is a significant leap forward, offering the public multi-image references and quality comparable to the best enterprise models. However, because FLUX.2 [dev] requires substantial compute resources, BFL, Comfy, and NVIDIA collaborated to achieve a major breakthrough: reducing the FLUX.2 [dev] memory requirement by more than 40% and enabling local deployment through ComfyUI. This optimization, using FP8 precision, has made FLUX.2…

Streamlining CUB with a Single-Call API

The C++ template library CUB is a go-to for high-performance GPU primitive algorithms, but its traditional “two-phase” API, which separates memory estimation from allocation, can be cumbersome. While this programming model offers flexibility, it often results in repetitive boilerplate code. This post explains the shift from this API to the new CUB single-call API introduced in CUDA 13.1, which simplifies development by managing memory under the hood without sacrificing performance. What is CUB? If you need to run a standard algorithm (such as scan, histogram, or sort) on a GPU, CUB is likely the fastest way to do it. As a principal component of the NVIDIA CUDA Core Compute Libraries (CCCL), CUB is designed to abstract away the complexity of manual CUDA thread management without sacrificing performance. While libraries like Thrust provide a high-level, “host-side” interface similar to the C++…

NVIDIA DLSS 4.5 Delivers Super Resolution Upgrades and New Dynamic Multi Frame Generation

NVIDIA DLSS 4 with Multi Frame Generation has become the fastest-adopted NVIDIA gaming technology ever. Over 250 games and apps use it to make real-time path tracing possible—and upcoming titles for 2026, including PRAGMATA and Resident Evil Requiem, also plan to incorporate the software.

Today, developers can begin using the second-generation transformer model for DLSS Super Resolution to provide superior image quality. A more powerful DLSS Super Resolution model DLSS 4 introduced a transformer model architecture with NVIDIA GeForce RTX 50 Series GPUs. That enabled a leap in image…

Delivering Massive Performance Leaps for Mixture of Experts Inference on NVIDIA Blackwell

As AI models continue to get smarter, people can rely on them for an expanding set of tasks. This leads users—from consumers to enterprises—to interact with AI more frequently, meaning that more tokens need to be generated. To serve these tokens at the lowest possible cost, AI platforms need to deliver the best possible token throughput per watt. Through extreme co-design across GPUs, CPUs, networking, software, power delivery, and cooling, NVIDIA continues to drive up token throughput per watt, which reduces cost per million tokens. Additionally, NVIDIA continues to enhance its software stacks to achieve even greater levels of performance from existing platforms. This increases the value of the large installed base of NVIDIA GPUs across cloud service providers (CSPs), GPU clouds, model builders, enterprises, and others, enabling that infrastructure to remain productive for longer. In this post, we show…

How Higgsfield turns simple ideas into cinematic social videos

Short-form video drives modern commerce, but producing video that actually performs is harder than it looks. Clips that feel effortless on TikTok, Reels, and Shorts are built on invisible rules: hook timing, shot rhythm, camera motion, pacing, and other subtle cues that make content feel “native” to whatever is trending. Higgsfield(opens in a new window) is a generative media platform that lets teams create short-form, cinematic videos from a product link, an image, or a simple idea. Using OpenAI GPT‑4.1 and GPT‑5 to plan and Sora 2 to create, the system generates roughly 4 million videos per day, turning minimal input into structured, social-first video. “Users rarely describe what a model actually needs. They describe what they want to feel. Our job is to translate that intent into something a video model can execute, using OpenAI models to turn goals…

From hard refusals to safe-completions: toward output-centric safety training

From hard refusals to safe-completions: toward output-centric safety training Introduced in GPT‑5, safe-completion is a new safety-training approach to maximize model helpfulness within safety constraints. Compared to refusal-based training, safe-completion improves both safety and helpfulness, especially in dual-use domains. If a user asks ChatGPT for the minimum energy needed to ignite a firework display, should it give a helpful answer? The user could be preparing for a July 4th display or a research project for school … or build explosives. As a result, giving a helpful answer could be harmless or harmful depending on the user’s (apparent) intent. This kind of prompt is dual-use: a question with unclear intent, where information could be used in benign or malicious ways. Dual-use problems are especially prevalent in risk areas such as biology and cybersecurity. In the past, production models such as ChatGPT…

Addendum to GPT-4o System Card: 4o image generation

Addendum to GPT‑4o System Card: 4o image generation 4o image generation is a new, significantly more capable image generation approach than our earlier DALL·E 3 series of models. It can create photorealistic output. It can take images as inputs and transform them. It can follow detailed instructions, including reliably incorporating text into images. And because it is embedded natively, deep in the architecture of our omnimodal GPT‑4o model, 4o image generation can use everything it knows to apply these capabilities in subtle and expressive ways, creating images that are not only beautiful, but also useful. 4o image generation benefits from our existing safety infrastructure, and from lessons we have learned deploying DALL·E and Sora. At the same time, these new capabilities also bring some new risks. This addendum to the GPT‑4o system card describes the marginal risks we’ve focused on,…

Enabling Up to 41% Faster Pre-training: MXFP8 and DeepEP for DeepSeek-V3 on B200 with TorchTitan

TL;DR In a joint effort between PyTorch and Nebius, we enabled training DeepSeek-V3 Mixture-of-Experts models (16B and 671B) on a 256-GPU NVIDIA B200 cluster using TorchTitan. We evaluated two orthogonal optimizations on top of a BF16 baseline: MXFP8 training (via TorchAO) and DeepEP communication acceleration (via DeepEP). The highlights: - DeepSeek-V3 671B: DeepEP alone yields 859 token/sec (+32%) over the BF16 baseline (651 token/sec). Adding MXFP8 on grouped GEMMs and combining that with DeepEP pushes the performance to 918 token/sec, a +41% total throughput gain. - DeepSeek-V3 16B MoE: Loss convergence experiments over 1,500 steps confirm that MXFP8 training is equivalent to BF16 (No degradation in convergence behavior). All experiments ran on Nebius Cloud using open-source PyTorch-native tooling and are fully reproducible. Please refer to the last section (Reproducibility), to get access to all recipes. Why This Experiment Training frontier-scale…

Gemma 4 audio with MLX

12th April 2026 Thanks to a tip from Rahim Nathwani, here's a uv run recipe for transcribing an audio file on macOS using the 10.28 GB Gemma 4 E2B model with MLX and mlx-vlm: uv run --python 3.13 --with mlx_vlm --with torchvision --with gradio \ mlx_vlm.generate \ --model google/gemma-4-e2b-it \ --audio file.wav \ --prompt "Transcribe this audio" \ --max-tokens 500 \ --temperature 1.0 I tried it on this 14 second .wav file and it output the following: This front here is a quick voice memo. I want to try it out with MLX VLM. Just going to see if it can be transcribed by Gemma and how that works. (That was supposed to be "This right here..." and "... how well that works" but I can hear why it misinterpreted that as "front" and "how that works".) Recent articles -…

AI failure could trigger the next financial crisis, warns Elizabeth Warren

“I know a bubble when I see one.” AI failure could trigger the next financial crisis, warns Elizabeth Warren ‘The first big stumble will have everyone running for the exits.’ ‘The first big stumble will have everyone running for the exits.’ That’s what Sen. Elizabeth Warren (D-MA), who led the push to create a new consumer financial regulator in the wake of the 2008 recession, told a crowd at a Vanderbilt Policy Accelerator event in Washington, DC, on Wednesday. Warren warned of what she called “striking” parallels to that crisis in the AI industry. While she believes the technology has “enormous potential,” she warned that AI companies’ massive spending and borrowing practices are creating a tinderbox and Congress should step in. Though the AI industry has grown rapidly, Warren said the pace isn’t keeping up with their spending, requiring them…

Silicon Valley has forgotten what normal people want

One of the most mortifying things about knowing a lot of techies is listening to them tell me excitedly about some very important discovery that they believe they have made. Recently, I ran into an acquaintance of mine, who began talking my ear off about an amazing discovery he’d made with LLMs. Knowledge, it turns out, is structured into language! You could put one word into ChatGPT and it might understand what you wanted, or make up a word and see if it understood what you meant! These amazing new tools have revealed that the English corpus contains so much about its speakers!

Prego Has a Dinner-Conversation-Recording Device, Capisce?

Prego, the pasta sauce company, is getting into hardware with a device that sits on your table and records dinner conversations. No, this isn’t April Fools’. The Connection Keeper is a round puck that houses two microphones for recording around the table. The recorder was developed in partnership with StoryCorps, the 23-year-old nonprofit that has recorded conversations with more than 720,000 people about their lives. The Connection Keeper is more of a publicity stunt than a readily available product. Fewer than 100 will be made. The pucks look more like a tuna can than what you’d associate with the pasta sauce brand—small and meant to be tucked aside so as not to attract attention. The whole goal here, Prego and StoryCorps say, is to advocate for keeping people off their phones during dinner. “Everything now is AI, and everyone has…

Schematik Is ‘Cursor for Hardware.’ Anthropic Wants In

Samuel Beek knew he had a problem when he blew every fuse in his house. The culprit was an electric door opener he had built himself, guided by instructions for wiring and piecing together a device drummed up by ChatGPT. Turns out, the chatbot wasn’t so great at distinguishing between wet and dry connections, so the device he had built sent out a surge of misallocated power that zapped everything else. Oops. Beek, based in Amsterdam, admits he is not a hardware guy. But he had that itch and now really just wanted to make something that wouldn’t explode. “That's the difference: Your fuses blow out, or you have a solid product,” Beek says. “That was kind of a learning experience for me to be more careful, but also to build AI that deeply understands what it's talking about.” He…
