Building Blocks for Foundation Model Training and Inference on AWS

Building Blocks for Foundation Model Training and Inference on AWS Figure: Adapted from "AI's Three Scaling Laws, Explained" (NVIDIA Blog). Taken together, these scaling regimes push the foundation-model lifecycle—pre-training, post-training, and inference—toward convergent infrastructure requirements: tightly coupled accelerator compute, a high-bandwidth low-latency network, and a distributed storage backend. They also raise the importance of orchestration for resource management, and of application- and hardware-level observability to maintain cluster health and diagnose performance pathologies at scale. Another key trend is the increasing reliance of the foundation-model lifecycle on an open-source software (OSS) ecosystem that spans model development frameworks, cluster resource management, and operational tooling. At the cluster layer, resource management is typically provided by systems such as Slurm and Kubernetes. Model development and distributed training are commonly implemented in frameworks such as PyTorch and JAX. Monitoring and visualization—that is, observability—are often achieved…

MachinaCheck: Building a Multi-Agent CNC Manufacturability System on AMD MI300X

MachinaCheck: Building a Multi-Agent CNC Manufacturability System on AMD MI300X The Problem We Solved Walk into any small CNC machine shop and ask the manager how they decide whether to accept a customer job. The answer is almost always the same: they print the drawing, read every dimension by hand, walk around the shop checking which tools are available, estimate whether their machines can hold the required tolerances, and write notes on a clipboard. The whole process takes 30 to 60 minutes per drawing. For a busy shop receiving 10 to 20 RFQs per week, that is 5 to 20 hours of skilled manager time spent on feasibility analysis alone. Sometimes they get it wrong. They accept a job, start production, and discover halfway through that they don't have the right tap or that their mill cannot hold the tolerance…

CyberSecQwen-4B: Why Defensive Cyber Needs Small, Specialized, Locally-Runnable Models

CyberSecQwen-4B: Why Defensive Cyber Needs Small, Specialized, Locally-Runnable Models Why this matters Frontier models are very good at very many things. They are also expensive to call, ship every prompt off to someone else's datacenter, and are explicitly trained to refuse the messy edge cases a real defender lives in incident write-ups, attacker-grade payloads found in your own logs, vulnerability disclosure drafts. Defensive cybersecurity is not a place where any of those tradeoffs are acceptable. - Sensitive evidence stays internal. A SOC analyst triaging a leaked credential dump, a malware reverse-engineer dissecting a sample, a vulnerability researcher writing up a CVE — none of them should be pasting that content into a hosted API. The data itself can be the breach. - Per-call API cost compounds. A mid-size SOC processes thousands of low-confidence alerts per day. Hosted-API costs for "explain…

EMO: Pretraining mixture of experts for emergent modularity

EMO: Pretraining mixture of experts for emergent modularity Today we're releasing EMO, a new mixture-of-experts (MoE) model pretrained end-to-end so that modular structure emerges directly from the data without relying on human-defined priors. EMO lets you use a small subset of its experts - just 12.5% of the total - for a given task while keeping near full-model performance, and still works as a strong general-purpose model when all experts are used together. Large language models are typically trained and deployed as monolithic systems: a single model is initialized, pretrained, fine-tuned, and served as one unified entity. But applications often need only a subset of capabilities, such as code generation, mathematical reasoning, or domain-specific knowledge. As frontier language models routinely reach trillions of parameters, using and adapting the full model becomes impractical for most users and incurs unnecessary computational cost…

MedQA: Fine-Tuning a Clinical AI on AMD ROCm — No CUDA Required

MedQA: Fine-Tuning a Clinical AI on AMD ROCm — No CUDA Required The Idea Medical question answering is one of those tasks where the stakes are genuinely high. A model that confidently picks the wrong answer on a clinical MCQ isn't just wrong — it's dangerous. At the same time, most open-source medical AI work assumes you have an NVIDIA GPU. CUDA is the default. Everything else is an afterthought. This project challenges that assumption. MedQA is a LoRA fine-tuned clinical question-answering model built entirely on AMD hardware using ROCm. It takes a multiple-choice medical question and returns both the correct answer letter and a clinical explanation of the reasoning. The entire training pipeline — from data loading to adapter export — runs on an AMD Instinct MI300X without a single CUDA dependency. - 🤗 Model on HuggingFace Hub: HK2184/medqa-qwen3-lora…

vLLM V0 to V1: Correctness Before Corrections in RL

vLLM V0 to V1: Correctness Before Corrections in RL TL;DR. vLLM V1 matched our vLLM V0 reference after we fixed four things: processed rollout logprobs, V1-specific runtime defaults, the inflight weight-update path, and the fp32 lm_head used for the final projection. We fixed the backend behavior before changing the RL objective. The reference run used vLLM 0.8.5 ; the V1 runs used vLLM 0.18.1 . Figure 1 shows the final result. The red run is the initial V1 attempt, and the green run is the final V1 run after the fixes described below. Migration Objective vLLM V1 is a substantial rewrite of the V0 engine. Our migration target was therefore deliberately narrow: - verify that V1 returned rollout logprobs in the form the trainer expected - rerun the same workload against the V0 reference - evaluate objective-level changes only after…

Granite 4.1 LLMs: How They’re Built

Granite 4.1 LLMs: How They’re Built Authors: Granite Team, IBM TL;DR — Granite 4.1 is a family of dense, decoder‑only LLMs (3B, 8B, and 30B) trained on ~15T tokens using a multi‑stage pre‑training pipeline, including long‑context extension of up to 512K tokens. The models are further refined with supervised fine‑tuning on ~4.1M high‑quality curated samples and reinforcement learning via on‑policy GRPO with DAPO loss (Yu et al., 2025). Notably, the 8B instruct model matches or surpasses the previous Granite 4.0‑H‑Small (32B‑A9B MoE) despite using a simpler dense architecture with fewer parameters. All Granite 4.1 models are released under the Apache 2.0 license. Links: Overview Building high‑quality small language models goes beyond simply scaling compute—it requires rigorous data curation throughout training. For Granite 4.1, we prioritized data quality over quantity, progressively refining the data mixture across five pre‑training stages. We further…

AI evals are becoming the new compute bottleneck

AI evals are becoming the new compute bottleneck Summary. AI evaluation has crossed a cost threshold that changes who can do it. The Holistic Agent Leaderboard (HAL) recently spent about $40,000 to run 21,730 agent rollouts across 9 models and 9 benchmarks. A single GAIA run on a frontier model can cost $2,829 before caching. Exgentic's $22,000 sweep across agent configurations found a 33× cost spread on identical tasks, isolating scaffold choice as a first-order cost driver, and UK-AISI recently scaled agentic steps into the millions to study inference-time compute. In scientific ML, The Well costs about 960 H100-hours to evaluate one new architecture and 3,840 H100-hours for a full four-baseline sweep. While compression techniques have been proposed for static benchmarks, new agent benchmarks are noisy, scaffold-sensitive, and only partly compressible. Training-in-the-loop benchmarks are expensive by construction, and when you…

DeepSeek-V4: a million-token context that agents can actually use

DeepSeek-V4: a million-token context that agents can actually use Focusing on long running agentic workloads. Running a frontier open model as an agent today breaks in predictable ways. The model stops. You reprompt. The trace blows past the context budget, or the KV cache fills the GPU, or tool-call round trips degrade halfway through a long task. V4 is built to fix these known failures, and point the way for the community to follow. This post covers three things: what the architecture does differently to make long-context inference cheap, the agent-specific post-training decisions that compound on top of it, and some takeaways from the paper that help reason about these changes.

Mythos is a “frontier AI model”, a large language model (LLM) that can be used to process software code (among many other things). This follows a general trend in LLM development, where LLM performance on code-related tasks has recently skyrocketed. What’s particularly significant about Mythos is the system it’s embedded within: It's the system, not the model alone, that has enabled Mythos to rapidly find and patch software vulnerabilities. Understanding this distinction is key to understanding the current landscape of AI cybersecurity.

The resulting tomaarsen/Qwen3-VL-Embedding-2B-vdr demonstrates how much performance you can gain by finetuning on your own domain. On my evaluation data, the finetuned model achieves an NDCG@10 of 0.947 compared to the base model's 0.888, and outperforms all existing VDR models I tested against, including models up to 4x its size.

The pickle-based formats that dominated the ecosystem at the time meant that there was a very real risk you’d be running malicious code. While this was an acceptable risk when ML was still budding, it would become unacceptable as open model sharing became central to how the ML community works. The format we built is intentionally simple: a JSON header with a hard limit of 100MB, describing tensor metadata, followed by raw tensor data. Zero-copy loading that maps tensors directly from disk. Lazy loading so you can read individual weights without deserializing an entire checkpoint. What we didn't fully anticipate was how broadly it…

TRL v1.0: Post-Training Library Built to Move with the Field

TRL v1.0: Post-Training Library Built to Move with the Field TRL now implements more than 75 post-training methods. But coverage isn’t the goal by itself. What matters is making these methods easy to try, compare, and actually use in practice. The design of the library wasn’t decided upfront. It is the result of years of iteration — the first commit goes back more than six years — and it has been shaped by everything the field threw at it: new algorithms, new models, shifting paradigms. Over time, this pressure forced the codebase toward a very specific design. Parts of it might look unusual at first, but like in many evolutionary codebases, they exist for a reason. TRL is built for a field that doesn’t sit still. So the question is not how to design the perfect abstraction. It is how…

A New Framework for Evaluating Voice Agents (EVA)

A New Framework for Evaluating Voice Agents (EVA) Introduction Conversational voice agents present a distinct evaluation challenge: they must simultaneously satisfy two objectives — accuracy (completing the user's task correctly and faithfully) and conversational experience (doing so naturally, concisely, and in a way appropriate for spoken interaction). These objectives are deeply intertwined: mishearing a confirmation code renders perfect LLM reasoning meaningless, a wall of options overwhelms a caller who can't skim spoken output, and delayed responses can pass every accuracy check while remaining unusable in practice.

State of Open Source on Hugging Face: Spring 2026

State of Open Source on Hugging Face: Spring 2026 This post builds on an earlier analysis conducted mid-2025, available here, which examined what the Hugging Face Community is building. We recommend reading additional perspectives on the open source ecosystem in and outside of Hugging Face from the Data Provenance Initiative, Interconnects, OpenRouter and a16z, and MIT and the Linux Foundation. As the Hugging Face ecosystem is distributed, analyses are a combination of Hugging Face and community members' work, each of which is appropriately credited. Activity in the open source AI ecosystem has rapidly grown, with the number of users, model, and dataset repositories all close to doubling. In 2025, Hugging Face grew to 13 million users, more than 2 million public models, and over 500,000 public datasets. This growth signals more than increased interest in open source; it reflects a…

Holotron-12B - High Throughput Computer Use Agent

Holotron-12B - High Throughput Computer Use Agent We're thrilled to release Holotron-12B, a multimodal computer-use model from H Company. Post-trained from the open NVIDIA Nemotron-Nano-2 VL model on H Company’s proprietary data mixture, Holotron-12B is the result of a close collaboration between our research labs to engineer a new type of model optimized primarily for scale and performance in production. H Company is part of the NVIDIA Inception Program. The model is now available on Hugging Face. Why We Built Holotron-12B Most multimodal models today optimize primarily for static vision or following instructions. Holotron-12B, just like our Holo2 model, however, has a different goal: serving as a policy model for computer-use agents that must perceive, decide, and act efficiently in interactive environments. With Holotron-12B, we wanted to create a model that could efficiently and effectively scale in production while handling…

Introducing Storage Buckets on the Hugging Face Hub

Introducing Storage Buckets on the Hugging Face Hub Storage Buckets are built exactly for this: mutable, S3-like object storage you can browse on the Hub, script from Python, or manage with the hf CLI. And because they are backed by Xet, they are especially efficient for ML artifacts that share content across files. Why we built Buckets Git starts to feel like the wrong abstraction pretty quickly when you're dealing with: - Training clusters writing checkpoints and optimizer states throughout a run - Data pipelines processing raw datasets iteratively - Agents storing traces, memory, and shared knowledge graphs The storage need in all these cases is the same: write fast, overwrite when needed, sync directories, remove stale files, and keep things moving. A Bucket is a non-versioned storage container on the Hub. It lives under a user or organization namespace,…

Keep the Tokens Flowing: Lessons from 16 Open-Source RL Libraries

Keep the Tokens Flowing: Lessons from 16 Open-Source RL Libraries TL;DR -- For those of you who don't have time to read 5,000 words about async RL plumbing (we get it, you have models to train): - The problem: In synchronous RL (reinforcement learning) training, data generation (model inference to create data samples) dominates wall-clock time -- a single batch of 32K-token rollouts on a 32B (32-billion parameter) model can take hours, while the GPUs used for training remain idle. - The solution everyone converged on: Disaggregate (separate) inference and training onto different GPU pools, connect them with a rollout buffer (temporary storage for model outputs), and transfer weights asynchronously (without waiting), so neither side waits for the other. - We surveyed 16 open-source libraries that implement this pattern and compared them across 7 axes: orchestration primitives, buffer design, weight…

Bringing Robotics AI to Embedded Platforms: Dataset Recording, VLA Fine‑Tuning, and On‑Device Optimizations

Bringing Robotics AI to Embedded Platforms: Dataset Recording, VLA Fine‑Tuning, and On‑Device Optimizations Authors: Enzo Ruedas, Tess Boivin Recent advances in Large Language Models have enabled the transition from text-only reasoning to multimodal systems. First, with the integration of visual perception in Vision–Language Models (VLMs), and more recently with the generation of robot actions in Vision–Language–Action (VLA) models. Deploying these models on embedded robotic platforms remains a challenge due to tight constraints in terms of compute, memory, and power, as well as real-time control requirements. In synchronous control pipelines, while the VLA is running inference, the arm is idle awaiting commands leading to oscillatory behavior and delayed corrections. To tackle that, asynchronous Inference can enable smooth and continuous motion by dissociating generation from execution. However, to be effective, the end-to-end inference latency must remain shorter than the action execution duration.…

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?

IBM and UC Berkeley Diagnose Why Enterprise Agents Fail Using IT-Bench and MAST

IBM and UC Berkeley Diagnose Why Enterprise Agents Fail Using IT-Bench and MAST ITBench HF Space ITBench HF Dataset MAST HF Dataset ITBench Github MAST Github IBM Research and UC Berkeley collaborated to study how agentic LLM systems break in real-world IT automation, for tasks involving incident triage, logs/metrics queries, and Kubernetes actions in long-horizon tool loops. Benchmarks typically reduce performance to a single number, telling you whether an agent failed but never why. To solve this black-box problem, we applied MAST (Multi-Agent System Failure Taxonomy), an emerging practice for diagnosing agentic reliability ). By leveraging MAST to analyze ITBench—the industry benchmark for SRE, Security, and FinOps automation—we turned raw execution traces into structured failure signatures, revealing exactly what broke and how to fix it.

Custom Kernels for All from Codex and Claude tl;dr: We built an agent skill that teaches coding agents how to write production CUDA kernels. Then we pointed Claude and Codex at two real targets: a diffusers pipeline and a transformers model. The agents produced working kernels for both, with correct PyTorch bindings and benchmarks, end to end. Writing CUDA kernels is hard. Writing CUDA kernels that correctly integrate with transformers and diffusers is harder. There are architecture-specific memory access patterns, vectorization strategies, warp shuffle reductions, and a dozen integration pitfalls that trip up even experienced developers. It is exactly the kind of specialized, high-stakes problem where agent skills shine. We gave coding agents the domain knowledge they need, like which GPU architecture to target, how to structure a kernel-builder project, when to use shared memory versus registers, and how to…

Modern Standard Arabic coexists with a rich landscape of regional dialects that differ significantly in vocabulary, syntax, phonology, and cultural grounding. These dialects are the primary medium of daily communication, oral storytelling, poetry, and social interaction. However, most existing benchmarks for Arabic large language models focus almost exclusively on Modern Standard Arabic, leaving dialectal Arabic largely under-evaluated and under-represented.

Tokenization in Transformers v5: Simpler, Clearer, and More Modular

Tokenization in Transformers v5: Simpler, Clearer, and More Modular Transformers v5 redesigns how tokenizers work. The big tokenizers reformat separates tokenizer design from trained vocabulary (much like how PyTorch separates neural network architecture from learned weights). The result is tokenizers you can inspect, customize, and train from scratch with far less friction. TL;DR: This blog explains how tokenization works in Transformers and why v5 is a major redesign, with clearer internals, a clean class hierarchy, and a single fast backend. It’s a practical guide for anyone who wants to understand, customize, or train model-specific tokenizers instead of treating them as black boxes.

The Open Evaluation Standard: Benchmarking NVIDIA Nemotron 3 Nano with NeMo Evaluator

The Open Evaluation Standard: Benchmarking NVIDIA Nemotron 3 Nano with NeMo Evaluator NVIDIA released Nemotron 3 Nano 30B A3B with an explicitly open evaluation approach to make that distinction clear. Alongside the model card, we are publishing the complete evaluation recipe used to generate the results, built with the NVIDIA NeMo Evaluator library, so anyone can rerun the evaluation pipeline, inspect the artifacts, and analyze the outcomes independently. We believe that open innovation is the foundation of AI progress. This level of transparency matters because most model evaluations omit critical details. Configs, prompts, harness versions, runtime settings, and logs are often missing or underspecified, and even small differences in these parameters can materially change results. Without a complete recipe, it’s nearly impossible to tell whether a model is genuinely more intelligent or simply optimized for a benchmark. This blog shows…

New in llama.cpp: Model Management

New in llama.cpp: Model Management Reminder: llama.cpp server is a lightweight, OpenAI-compatible HTTP server for running LLMs locally. This feature was a popular request to bring Ollama-style model management to llama.cpp. It uses a multi-process architecture where each model runs in its own process, so if one model crashes, others remain unaffected. Quick Start Start the server in router mode by not specifying a model: llama-server This auto-discovers models from your llama.cpp cache (LLAMA_CACHE or ~/.cache/llama.cpp ). If you've previously downloaded models via llama-server -hf user/model , they'll be available automatically. You can also point to a local directory of GGUF files: llama-server --models-dir ./my-models Features - Auto-discovery: Scans your llama.cpp cache (default) or a custom --models-dir folder for GGUF files - On-demand loading: Models load automatically when first requested - LRU eviction: When you hit --models-max (default: 4), the…

Introducing swift-huggingface: The Complete Swift Client for Hugging Face

Introducing swift-huggingface: The Complete Swift Client for Hugging Face You can start using it today as a standalone package, and it will soon integrate into swift-transformers as a replacement for its current HubApi implementation. The Problem When we released swift-transformers 1.0 earlier this year, we heard loud and clear from the community: - Downloads were slow and unreliable. Large model files (often several gigabytes) would fail partway through with no way to resume. Developers resorted to manually downloading models and bundling them with their apps — defeating the purpose of dynamic model loading. - No shared cache with the Python ecosystem. The Python transformers library stores models in~/.cache/huggingface/hub . Swift apps downloaded to a different location with a different structure. If you'd already downloaded a model using the Python CLI, you'd download it again for your Swift app. - Authentication…

DeepMath: A lightweight math reasoning Agent with smolagents

DeepMath: A lightweight math reasoning Agent with smolagents By Intel AI Software Group DeepMath is an aligned math reasoning agent built on Qwen3-4B Thinking and fine-tuned with GRPO (Group Relative Policy Optimization). Instead of verbose text, the model emits tiny Python snippets for intermediate steps, runs them in a secure sandbox, and folds the results back into its reasoning, reducing errors and output length. The agent is implemented using the smolagents library. We evaluate DeepMath on four math datasets: MATH500, AIME, HMMT, and HLE, and show that: 🤖 The math agent alone reduces output lengths by up to 66%, while often improving accuracy. ⚡ GRPO training improves the agent performance even further, in almost all benchmarks. 👉 Code and evaluation scripts: https://github.com/IntelLabs/DeepMath 👉 Model: https://huggingface.co/Intel/deepmath-v1 Why DeepMath?

Diffusers welcomes FLUX-2

Welcome FLUX.2 - BFL’s new open image generation model 🤗 🚨 FLUX.2 is not meant to be a drop-in replacement of FLUX.1, but a new image generation and editing model. Table of contents FLUX.2: A Brief Introduction FLUX.2 can be used for both image-guided and text-guided image generation. Furthermore, it can take multiple images as reference inputs, while producing the final output image. Below, we briefly discuss the key changes introduced in FLUX.2. Text encoder First, instead of two text encoders as in Flux.1, it uses a single text encoder — Mistral Small 3.1. Using a single text encoder greatly simplifies the process of computing prompt embeddings. The pipeline allows for a max_sequence_length of 512. Instead of using a single-layer output for the prompt embedding, FLUX.2 stacks outputs from intermediate layers, which have been known to be more beneficial. DiT…

Continuous batching from first principles

Continuous batching TL;DR: in this blog post, starting from attention mechanisms and KV caching, we derive continuous batching by optimizing for throughput. If you've ever used Qwen, Claude, or any other AI chatbot, you've probably noticed something: it takes a while for the first word of the response to appear, and then words appear one-by-one on your screen with (hopefully) a regular and fast-paced frequency. That's because at the heart of it, all LLMs are just fancy next token predictors. An LLM first processes your entire prompt to produce one new token. Then it keeps adding tokens one by one, each time reading everything that came before, until it decides generation is over. This generation process is computationally expensive: it requires passing the input through billions of parameters for each token generated. To make these models practical for real-world applications,…

Building Deep Research: How we Achieved State of the Art

Building Deep Research: How we Achieved State of the Art Building for the Future Agent Harness The task of building an agent harness is to create a software layer that enhances a model’s runtime execution through context management, tool invocations, loop control, orchestration, and error handling. Building applications on top of rapidly improving models is, however, a modern engineering challenge. How can we design software today that absorbs the performance gains from future model releases? This requires forecasting how models will evolve, staying optimistic about their progress, limiting assumptions, and avoiding hand-crafted optimizations. We learned this the hard way seven months ago, when we had to abandon our first attempt at deep research and rebuild the entire system from scratch. The first architecture was complicated and sophisticated (we thought this was a good thing), but its assumptions became bottlenecks when…

20x Faster TRL Fine-tuning with RapidFire AI

20x Faster TRL Fine-tuning with RapidFire AI Why this matters When fine-tuning or post-training LLMs, teams often do not have the time and/or budget to compare multiple configs even though that can significantly boost eval metrics. RapidFire AI lets you launch multiple TRL configs concurrently--even on a single GPU--and compare them in near real time via a new adaptive, chunk-based scheduling and execution scheme. In internal benchmarks referenced in the TRL page, this delivers ~16–24× higher experimentation throughput than sequentially comparing configs one after another, enabling you to reach much better metrics much faster. RapidFire AI establishes live three-way communication between your IDE, a metrics dashboard, and a multi-GPU execution backend What you get, out of the box Drop-in TRL wrappers — Use RFSFTConfig ,RFDPOConfig , andRFGRPOConfig as near-zero-code replacements for TRL's SFT/DPO/GRPO configs.Adaptive chunk-based concurrent training — RapidFire AI…

It's a lot, and it adds up quickly. When I interviewed developers about building AI-powered apps, friction with model integration came up immediately. One developer put it bluntly: I thought I'd quickly use the demo for a test and maybe a quick and dirty build but instead wasted so much time. Drove me nuts.

Apriel-H1: The Surprising Key to Distilling Efficient Reasoning Models

Apriel-H1: The Surprising Key to Distilling Efficient Reasoning Models When MiniMax published their M2 post-mortem in October explaining why they abandoned efficient attention at 230B scale, the narrative briefly became "efficient attention is dead." Within days, Kimi Linear proved otherwise. The real lesson: it depends on your constraints. Our constraint was simple: we had a strong 15B reasoning model and needed to make it efficient without starting over. No infinite compute for 20T-token pretraining. No luxury of architectural co-design from day one. Just a practical question: can you retrofit efficiency into an existing model through distillation? Spoilers: yes, but only if you ignore your intuition about what data to use. What We Built The Apriel-H1 family: seven checkpoints spanning 25-40 Mamba layers (out of 50 total), showing the complete efficiency-quality frontier. Our flagship Apriel-H1-15b-Thinker-SFT achieves 2.1x throughput with minimal quality…

An agent might crush a tool-use leaderboard but fail spectacularly at a simple, real-world task. This gap between benchmark performance and practical usability is one of the biggest challenges in the field. When we designed M2, we knew we had to tackle this problem head-on. This led us to two core, and sometimes conflicting, objectives: - Excel on Open-Source Benchmarks. Benchmarks are essential for measuring "pure" capabilities.

In the past few months, highly performant open-weight AI models’ inference in China has started to be powered by chips such as Huawei’s Ascend and Cambricon, with some models starting to be trained using domestic chips. There are two large implications for policymakers and AI researchers and developers respectively: U.S. export controls correlates with expedited Chinese chip production, and chip scarcity in China likely incentivized many of the innovations that are open-sourced and shaping global AI development. China’s chip development correlates highly with stronger export controls from the U.S. Under uncertainty of chip access, Chinese companies have innovated with both chip…
