Introducing Claude Opus 4.7 Product Apr 16, 2026 Our latest Opus model brings stronger performance across coding, agents, vision, and multi-step tasks, with greater thoroughness and consistency on the work that matters most.

Introducing Claude Opus 4.7 Our latest model, Claude Opus 4.7, is now generally available. Opus 4.7 is a notable improvement on Opus 4.6 in advanced software engineering, with particular gains on the most difficult tasks. Users report being able to hand off their hardest coding work—the kind that previously needed close supervision—to Opus 4.7 with confidence. Opus 4.7 handles complex, long-running tasks with rigor and consistency, pays precise attention to instructions, and devises ways to verify its own outputs before reporting back. The model also has substantially better vision: it can see images in greater resolution. It’s more tasteful and creative when completing professional tasks, producing higher-quality interfaces, slides, and docs. And—although it is less broadly capable than our most powerful model, Claude Mythos Preview—it shows better results than Opus 4.6 across a range of benchmarks: Last week we announced…

These organizations help our enterprise customers identify where Claude can provide the most value to…

Mar 5, 2026 Announcements Where things stand with the Department of War

Where things stand with the Department of War A statement from Dario Amodei Yesterday (March 4) Anthropic received a letter from the Department of War confirming that we have been designated as a supply chain risk to America’s national security. As we wrote on Friday, we do not believe this action is legally sound, and we see no choice but to challenge it in court. The language used by the Department of War in the letter (even supposing it was legally sound) matches our statement on Friday that the vast majority of our customers are unaffected by a supply chain risk designation. With respect to our customers, it plainly applies only to the use of Claude by customers as a direct part of contracts with the Department of War, not all use of Claude by customers who have such contracts.…

Announcements Feb 4, 2026 Claude is a space to think We’ve made a choice: Claude will remain ad-free. We explain why advertising incentives are incompatible with a genuinely helpful AI assistant, and how we plan to expand access without compromising user trust.

Claude is a space to think There are many good places for advertising. A conversation with Claude is not one of them. Advertising drives competition, helps people discover new products, and allows services like email and social media to be offered for free. We’ve run our own ad campaigns, and our AI models have, in turn, helped many of our customers in the advertising industry. But including ads in conversations with Claude would be incompatible with what we want Claude to be: a genuinely helpful assistant for work and for deep thinking. We want Claude to act unambiguously in our users’ interests. So we’ve made a choice: Claude will remain ad-free. Our users won’t see “sponsored” links adjacent to their conversations with Claude; nor will Claude’s responses be influenced by advertisers or include third-party product placements our users did not…

Anthropic tested removing Claude Code from the Pro plan

Anthropic caused a stir among developers with what appeared to be a surprise change to its pricing plan: The company signaled that Claude Code, the popular agentic development tool, would no longer be available to subscribers on the $20-per-month Pro plan. Users took to Reddit and X to point out that Anthropic’s pricing page for Claude explicitly showed Claude Code as not supported in the Pro plan. (It remained in the $100/month+ Max plan.) Some new users signing up for Pro subscriptions were unable to access Claude Code. Meanwhile, existing subscribers saw no interruption. After speculation and frustration spread, Anthropic’s head of growth, Amol Avasare, took to social media to clarify that this was a “small test on ~2% of new prosumer signups.” As for the reasoning, he explained: When we launched Max a year ago, it didn’t include Claude…

Report: Meta will train AI agents by tracking employees' mouse, keyboard use

Meta will begin tracking the mouse movements, clicks, and keystrokes of its US employees to generate high-quality training data for future AI agents, Reuters reports. The news organization cites internal memos posted by the Meta Superintelligence Labs team in reporting on the new Model Capability Initiative employee-tracking software. That software will operate on specific work-related apps and websites and also make use of periodic screenshots to provide context for the AI training, according to the memo. “This is where all Meta employees can help our models get better simply by doing their daily work,” the memo reads, in part, Reuters reports. Meta spokesperson Andy Stone told Reuters that the collected training data will help Meta’s AI agents with tasks that it sometimes struggles with, including “things like mouse movements, clicking buttons, and navigating dropdown menus.” “If we’re building agents to…

OpenAI starts offering a biology-tuned LLM

On Thursday, OpenAI announced it had developed a large language model specifically trained on common biology workflows. Called GPT-Rosalind after Rosalind Franklin, the model appears to differ from most science-focused models from major tech companies, which have generally taken a more generic approach that works for various fields. In a press briefing, Yunyun Wang, OpenAI’s Life Sciences Product Lead, said the system was designed to tackle two major roadblocks faced by current biology researchers. One is the massive datasets created by decades of genome sequencing and protein biochemistry, which can be too much for any one researcher to take in. The second is that biology has many highly specialized subfields, each with its own techniques and jargon. So, for example, a geneticist who finds themselves working on a gene that’s active in brain cells might struggle to understand the immense…

Gemini can now create personalized AI images by digging around in Google Photos

Google began rolling out “personal intelligence” in Gemini early this year, giving AI subscribers the option of a more customized experience when using the company’s chatbot. Today, it’s using personal intelligence to tie its image-generation model to Google Photos. If you opt in, generated images will have access to your photos and associated labels to simplify prompts and produce more accurate AI images. This change essentially streamlines an existing workflow. Google’s Nano Banana 2 is among the best AI image generators available, and it was already possible to feed it images of yourself or others to use as context for creating new AI content. Adding personal intelligence to the mix makes that process smoother by turning the image bot loose on the content of your photos, if indeed that’s something you want to do. It is generally true that adding…

Boston Dynamics’ robot dog now reads gauges and thermometers with Google's AI

Robots such as Boston Dynamics’ four-legged Spot can now accurately read analog thermometers and pressure gauges while roaming around factories and warehouses. Those improvements come courtesy of Google DeepMind’s newest robotic AI model that aims to enhance robotic capabilities for ‘embodied reasoning’ when interacting with physical environments. The new Gemini Robotics-ER 1.6 model announced on April 14 performs as a “high-level reasoning model for a robot” that can plan and execute tasks, according to Google DeepMind. This model also unlocks the capability of accurately reading instruments such as complex gauges and doing visual inspections using sight glasses that provide a transparent window to peek inside tanks and pipes—a performance upgrade that came about through Google DeepMind’s ongoing collaboration with robotics company Boston Dynamics. Boston Dynamics has a keen interest in testing both quadruped and humanoid robotic workers in a wide…

Adobe takes Creative Cloud into Claude Code-esque territory

Adobe has been putting task-specific AI tools and features into its creative productivity applications like Photoshop, Illustrator, and Premiere at a breakneck pace, but the latest product from the company—a chat-based interface that can handle complex, multi-modal projects across several applications—marks a significant shift in how users can think about its suite of tools. You could imprecisely but defensibly call it a sort of “Claude Code for creative apps.” On one hand, it’s meant to provide experienced creatives with an efficient way to offload mundane tasks across multiple apps. On the other, it’s meant to reduce the “barrier to entry” for inexperienced or casual users, in the wake of tool complexity that the company says has previously “widened the gap between idea and output.” Adobe has offered chat-based prompts within individual apps before and in other Firefly interfaces. It has…

UK gov's Mythos AI tests help separate cybersecurity threat from hype

Last week, Anthropic announced it was restricting the initial release of its Mythos Preview model to “a limited group of critical industry partners,” giving them time to prepare for a model that it said is “strikingly capable at computer security tasks.” Now, the UK government’s AI Security Institute (AISI) has published an initial evaluation of the model’s cyberattack capabilities that adds some independent public verification to those Anthropic reports. AISI’s findings show that Mythos isn’t significantly different from other recent frontier models in tests of individual cybersecurity-related tasks. But Mythos could set itself apart from previous models through its ability to effectively chain these tasks into the multistep series of attacks necessary to fully infiltrate some systems. “The Last Ones” finally falls AISI has been putting various AI models through specially designed Capture the Flag challenges since early 2023, when…

Google introduces "Skills" in Chrome to make Gemini prompts instantly reusable

Chrome is the most popular browser in the world, and the competition is not even close. So the browser is a key part of Google’s efforts to get everyone using its AI tools. The company’s chatbot has already infused various parts of the Chrome UI, and you can even turn Gemini loose to control the browser. The latest AI addition to Chrome comes in the form of “Skills,” reusable prompts you can access while browsing with a single click. Skills don’t so much add new functionality as they make it easier to repeat tasks that were already possible with Gemini in Chrome. Previously, you would have to reenter the prompt each time you wanted Gemini to do something in Chrome; whether that meant typing it or copy-pasting from a saved document, you had to do it manually. Saving those favorite…

Cost-efficient custom text-to-SQL using Amazon Nova Micro and Amazon Bedrock on-demand inference

Artificial Intelligence Cost-efficient custom text-to-SQL using Amazon Nova Micro and Amazon Bedrock on-demand inference Text-to-SQL generation remains a persistent challenge in enterprise AI applications, particularly when working with custom SQL dialects or domain-specific database schemas. While foundation models (FMs) demonstrate strong performance on standard SQL, achieving production-grade accuracy for specialized dialects requires fine-tuning. However, fine-tuning introduces an operational trade-off: hosting custom models on persistent infrastructure incurs continuous costs, even during periods of zero utilization. The on-demand inference of Amazon Bedrock with fine-tuned Amazon Nova Micro models offers an alternative. By combining the efficiency of LoRA (Low-Rank Adaptation) fine-tuning with serverless and pay-per-token inference, organizations can achieve custom text-to-SQL capabilities without the overhead cost incurred by persistent model hosting. Despite the additional inference time overhead of applying LoRA adapters, testing demonstrated latency suitable for interactive text-to-SQL applications, with costs scaling by…

3/28/2026 The Fine-Tuning Bottleneck Isn't the Algorithm

TL;DR: Integration friction and slow iteration cycles are the bottlenecks that actually stall fine-tuning — not the algorithm. We share the patterns we see across engagements, how teams like Cursor and Genspark broke through them, and where the workflow is heading: toward fully agentic fine-tuning loops that close themselves. Most teams that come to us for fine-tuning are not struggling with the training algorithm. They are struggling with everything around it: getting reward functions to talk to internal APIs without leaking data, waiting days between experiments because each step lives in a different tool, and figuring out whether the problem even calls for SFT, RFT, or DPO. Over the past year, working with a select group of the most innovative startups, digital natives, and Fortune 500 companies, we have seen these patterns repeat across every engagement. Every team that comes…

Falcon Perception

Falcon Perception TL;DR — Falcon Perception is a 0.6B-parameter early-fusion Transformer for open-vocabulary grounding and segmentation from natural language prompts. The model processes image patches + text in one sequence using a hybrid attention mask, and produces variable numbers of instances with a small, structured token interface and lightweight output heads. On SA-Co, Falcon Perception reaches 68.0 Macro-F1 (vs. 62.3 for SAM 3) with the main remaining gap being presence calibration (MCC 0.64 vs. 0.82). We also introduce PBench, a diagnostic benchmark that breaks down performance by capability (attributes, OCR-guided disambiguation, spatial constraints, relations) and by dense long-context crowded scenes. We also relase Falcon OCR, a 0.3B-parameter model which reaches a score of 80.3 and 88.6 on the olmOCR benchmark and OmniDocBench respectively, while having the highest throughput of any open source OCR model. This post is a brief, practical…

GGML and llama.cpp join HF to ensure the long-term progress of Local AI

GGML and llama.cpp join HF to ensure the long-term progress of Local AI Georgi Gerganov and team are joining HF with the goal of scaling and supporting the community behind ggml and llama.cpp as Local AI continues to make exponential progress in the coming years. We've been working with Georgi and team for quite some time (we even have awesome core contributors to llama.cpp like Son and Alek in the team already) so this has been a very natural process. llama.cpp is the fundamental building block for local inference, and transformers is the fundamental building block for model definition, so this is basically a match made in heaven. ❤️ What will change for llama.cpp, the open source project and the community? Not much – Georgi and team still dedicate 100% of their time maintaining llama.cpp and have full autonomy and…

One-Shot Any Web App with Gradio's gr.HTML

One-Shot Any Web App with Gradio's gr.HTML gr.HTML now supports custom templates, scoped CSS, and JavaScript interactivity. Which means you can build pretty much any web component — and Claude (or any other frontier LLM) can generate the whole thing in one shot: frontend, backend, and state management, all in a single Python file. We tested this by building different types of apps. Each one is a single Python file, no build step, deployable to Hugging Face Spaces in seconds. Productivity Apps Pomodoro Timer: A focus timer where a pixel-art tree grows as you work. Starts as a seed, sprouts branches, grows leaves. Complete a session and the tree joins your forest.

Custom Kernels for All from Codex and Claude

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…

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…

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…

The Download: bad news for inner Neanderthals, and AI warfare’s human illusion

The Download: bad news for inner Neanderthals, and AI warfare’s human illusion Plus: Despite blacklisting Anthropic, the White House wants its new model. This is today's edition of The Download, our weekday newsletter that provides a daily dose of what's going on in the world of technology. The problem with thinking you’re part Neanderthal There’s a theory that many of us have an “inner Neanderthal.” The idea is that Homo sapiens and a cousin species once bred, leaving some people today with a trace of Neanderthal DNA. This DNA is arguably the 21st century’s most celebrated discovery in human evolution. But in 2024, a pair of French geneticists called into question the theory's very foundations. They proposed that what scientists interpret as interbreeding could instead be explained by population structure—the way genes concentrate in smaller, isolated groups. Find out what…

Cut Checkpoint Costs with About 30 Lines of Python and NVIDIA nvCOMP

Training LLMs requires periodic checkpoints. These full snapshots of model weights, optimizer states, and gradients are saved to storage so training can resume after interruptions. At scale, these checkpoints become massive (782 GB for a 70B model) and frequent (every 15-30 minutes), generating one of the largest line items in a training budget. Most AI teams chase GPU utilization, training throughput, and model quality. Almost none look at what checkpointing is costing them. This is an expensive oversight. The synchronous checkpoint overhead of a 405B model on 128 NVIDIA Blackwell GPUs alone can cost $200,000 a month. By introducing a lossless compression step implemented with about 30 lines of Python, we can reduce storage costs by $56,000 every month. Mixture of experts (MoE) models save even more. We’ll break down how we got to that calculation and how NVIDIA nvComp…

Implementing Falcon-H1 Hybrid Architecture in NVIDIA Megatron Core

In the rapidly evolving landscape of large language model (LLM) development, NVIDIA Megatron Core has emerged as the foundational framework for training massive transformer models at scale. The open source library offers industry-leading parallelism and GPU-optimized performance. Now developed GitHub-first in the NVIDIA/Megatron-LM repo, Megatron Core is increasingly shaped by contributions from foundation model builders, making it a more flexible, future-proofed engine for open AI models. This post provides a technical overview of how the Technology Innovation Institute (TII), creators of the Falcon model family, have contributed to and integrated with Megatron Core and Megatron Bridge frameworks. The first section examines the implementation of the Falcon-H1 parallel hybrid architecture within Megatron Bridge, highlighting the challenges of coordinating heterogeneous Transformer and Mamba layers alongside non-learnable µP multipliers. The second section explores the integration of BitNet into Megatron Core, detailing the replacement…

Accelerating Long-Context Model Training in JAX and XLA

Large language models (LLMs) are rapidly expanding their context windows, with recent models supporting sequences of 128K tokens, 256K tokens, and beyond. However, training these models with extended context lengths presents significant computational and communication challenges. As context lengths grow, the memory and communication overhead of attention mechanisms scale quadratically, creating bottlenecks that traditional parallelism strategies struggle to address efficiently. This post demonstrates that integrating the NVSHMEM communication library into Accelerated Linear Algebra (XLA) compiler optimizes context parallelism. This integration enables the efficient training of Llama 3 8B model in JAX framework with sequences up to 256K tokens. Our results show that NVSHMEM provides up to 36% speedup over NVIDIA Collective Communications Library (NCCL) for long-context training workloads, particularly when combined with tensor parallelism across multiple nodes. The long-context training challenge To understand why NVSHMEM provides significant speedups for long-context…

Optimizing Communication for Mixture-of-Experts Training with Hybrid Expert Parallel

In LLM training, Expert Parallel (EP) communication for hyperscale mixture-of-experts (MoE) models is challenging. EP communication is essentially all-to-all, but due to its dynamics and sparseness (only topk experts per AI token instead of all experts), it’s challenging to implement and optimize. This post details an efficient MoE EP communication solution, Hybrid-EP, and its use in the NVIDIA Megatron family of frameworks, on NVIDIA Quantum InfiniBand and NVIDIA Spectrum-X Ethernet platforms. It also dives into the effectiveness of Hybrid-EP in real-world model training. Efficiency challenges of hyperscale MoE model training DeepSeek-V3 is a representative model of the new generation of large-scale fine-grained MoE models. Such models balance computational overhead with model performance through “hyperparameter size sparse activation,” but they also pose serious challenges for existing large-model training frameworks. - Communication efficiency bottlenecks: The MoE model relies on parallel experts and…

Accelerating the cyber defense ecosystem that protects us all

Trusted Access for Cyber is designed around a simple premise: advanced cyber capabilities should reach defenders broadly, but access should scale with trust, validation, and safeguards. Today we’re sharing the first organizations helping put that approach into practice, from open-source security teams and vulnerability researchers to enterprises operating some of the world’s most complex digital environments. The strength of this approach comes from the breadth of defenders involved. Cybersecurity is a team sport, and the systems people rely on are protected by organizations of many kinds, from major enterprises and security vendors to researchers, maintainers, public institutions, nonprofits, and smaller teams with limited security resources. Not every organization has the benefit of a 24x7 security team who is able to respond to incidents when they are disclosed on a Friday night(opens in a new window). It’s important for all software…

Trusted access for the next era of cyber defense

We are scaling up our Trusted Access for Cyber (TAC) program to thousands of verified individual defenders and hundreds of teams responsible for defending critical software.

Notion’s GPT‑5 rebuild unlocks autonomous AI workflows

Notion’s GPT‑5 rebuild unlocks autonomous AI workflows By rebuilding their agent system with GPT‑5, Notion created an AI workspace that can reason, act, and adapt across workflows. Results 7.6% Improvement over state-of-the-art models on outputs aligned with real user feedback In late 2022, within weeks of getting access to GPT‑4, Notion had already shipped a writing assistant, rolled out workspace-wide Q&A features, and integrated OpenAI models deeply across its search, content, and planning tools. But as models advanced - and users began asking agents to complete entire workflows - Notion’s team saw limits in their system architecture. The old pattern of prompting models to do isolated tasks was limiting the ceiling of what was capable on their platform. Agents needed to make decisions, orchestrate tools, and reason through ambiguity, and that shift required more than prompt engineering. “We didn’t want…

Doppel’s AI defense system stops attacks before they spread

Doppel’s AI defense system stops attacks before they spread With GPT‑5 and reinforcement fine-tuning (RFT), Doppel cut analyst workloads by 80% and now mitigates threats in minutes instead of hours. Results 80% reduced analyst workflows Results 3x threat handling capacity A single impersonation site can launch, target thousands of users, and vanish in under an hour. That’s more than enough time for an attacker to do real damage. And with generative tools, they can spin up hundreds more just like it. Doppel was built to defend organizations from deepfakes and online impersonations, but quickly realized AI meant threats could scale infinitely. Attackers no longer needed to handcraft scams; they could generate endless variants of phishing kits, spoofed domains, and impersonation accounts in seconds. “Damage from phishing attacks can happen within minutes as they spread across social media and messaging channels.…

Introducing AgentKit, new Evals, and RFT for agents

Today we’re launching AgentKit, a complete set of tools for developers and enterprises to build, deploy, and optimize agents. Until now, building agents meant juggling fragmented tools—complex orchestration with no versioning, custom connectors, manual eval pipelines, prompt tuning, and weeks of frontend work before launch. With AgentKit, developers can now design workflows visually and embed agentic UIs faster using new building blocks like: - Agent Builder: a visual canvas for creating and versioning multi-agent workflows - Connector Registry: a central place for admins to manage how data and tools connect across OpenAI products - ChatKit: a toolkit for embedding customizable chat-based agent experiences in your product We’re also expanding evaluation capabilities with new features like datasets, trace grading, automated prompt optimization, and third-party model support to measure and improve agent performance. Since releasing the Responses API and Agents SDK in…

Sora 2 System Card

Sora 2 is our new state of the art video and audio generation model. Building on the foundation of Sora, this new model introduces capabilities that have been difficult for prior video models to achieve– such as more accurate physics, sharper realism, synchronized audio, enhanced steerability, and an expanded stylistic range. The model follows user direction with high fidelity, enabling the creation of videos that are both imaginative and grounded in real-world dynamics. Sora 2 expands the toolkit for storytelling and creative expression, while also serving as a step toward models that can more accurately simulate the complexity of the physical world. Sora 2 will be available via sora.com, in a new standalone iOS Sora app, and in the future it will be available via our API. Sora 2’s advanced capabilities require consideration of new potential risks, including nonconsensual use…

TorchSpec: Speculative Decoding Training at Scale

Introduction Over the past year, large language models have rapidly expanded in both scale and capability. Frontier models such as Kimi K2.5, GLM 5, and Qwen 3.5 now operate with hundreds of billions of parameters and context windows stretching to millions of tokens, enabling long-context reasoning, agentic workflows, and complex tool use. As these models grow more capable, efficient inference has become one of the most critical systems challenges in LLM deployment. Speculative decoding is one of the most effective techniques for accelerating LLM generation. With speculative decoding, a lightweight draft model proposes several tokens ahead, while a larger target model verifies them in a single forward pass. When predictions are accepted, multiple tokens can be generated at once, improving throughput and latency. Recent approaches such as MTP(Multi Token Prediction) and EAGLE-3 demonstrate that well-trained draft models can deliver consistent…

Is Claude Code going to cost $100/month? Probably not - it's all very confusing

Is Claude Code going to cost $100/month? Probably not—it’s all very confusing 22nd April 2026 Anthropic today quietly (as in silently, no announcement anywhere at all) updated their claude.com/pricing page (but not their Choosing a Claude plan page, which shows up first for me on Google) to add this tiny but significant detail (arrow is mine, and it’s already reverted): The Internet Archive copy from yesterday shows a checkbox there. Claude Code used to be a feature of the $20/month Pro plan, but according to the new pricing page it is now exclusive to the $100/month or $200/month Max plans. Update: don’t miss the update to this post, they’ve already changed course a few hours after this change went live. So what the heck is going on? Unsurprisingly, Reddit and Hacker News and Twitter all caught fire. I didn’t believe…

Quoting Andreas Påhlsson-Notini

21st April 2026 AI agents are already too human. Not in the romantic sense, not because they love or fear or dream, but in the more banal and frustrating one. The current implementations keep showing their human origin again and again: lack of stringency, lack of patience, lack of focus. Faced with an awkward task, they drift towards the familiar. Faced with hard constraints, they start negotiating with reality. — Andreas Påhlsson-Notini, Less human AI agents, please.

Where's the raccoon with the ham radio? (ChatGPT Images 2.0)

Where’s the raccoon with the ham radio? (ChatGPT Images 2.0) 21st April 2026 OpenAI released ChatGPT Images 2.0 today, their latest image generation model. On the livestream Sam Altman said that the leap from gpt-image-1 to gpt-image-2 was equivalent to jumping from GPT-3 to GPT-5. Here’s how I put it to the test. My prompt: Do a where's Waldo style image but it's where is the raccoon holding a ham radio gpt-image-1 First as a baseline here’s what I got from the older gpt-image-1 using ChatGPT directly: I wasn’t able to spot the raccoon—I quickly realized that testing image generation models on Where’s Waldo style images (Where’s Wally in the UK) can be pretty frustrating! I tried getting Claude Opus 4.7 with its new higher resolution inputs to solve it but it was convinced there was a raccoon it couldn’t…

Claude Token Counter, now with model comparisons

20th April 2026 - Link Blog Claude Token Counter, now with model comparisons. I upgraded my Claude Token Counter tool to add the ability to run the same count against different models in order to compare them. As far as I can tell Claude Opus 4.7 is the first model to change the tokenizer, so it's only worth running comparisons between 4.7 and 4.6. The Claude token counting API accepts any Claude model ID though so I've included options for all four of the notable current models (Opus 4.7 and 4.6, Sonnet 4.6, and Haiku 4.5). In the Opus 4.7 announcement Anthropic said: Opus 4.7 uses an updated tokenizer that improves how the model processes text. The tradeoff is that the same input can map to more tokens—roughly 1.0–1.35× depending on the content type. I pasted the Opus 4.7 system…

Changes in the system prompt between Claude Opus 4.6 and 4.7

Changes in the system prompt between Claude Opus 4.6 and 4.7 18th April 2026 Anthropic are the only major AI lab to publish the system prompts for their user-facing chat systems. Their system prompt archive now dates all the way back to Claude 3 in July 2024 and it’s always interesting to see how the system prompt evolves as they publish new models. Opus 4.7 shipped the other day (April 16, 2026) with a Claude.ai system prompt update since Opus 4.6 (February 5, 2026). I had Claude Code take the Markdown version of their system prompts, break that up into separate documents for each of the models and then construct a Git history of those files over time with fake commit dates representing the publication dates of each updated prompt—here’s the prompt I used with Claude Code for the web.…

Quoting John Gruber

15th April 2026 The real goldmine isn’t that Apple gets a cut of every App Store transaction. It’s that Apple’s platforms have the best apps, and users who are drawn to the best apps are thus drawn to the iPhone, Mac, and iPad. That edge is waning. Not because software on other platforms is getting better, but because third-party software on iPhone, Mac, and iPad is regressing to the mean, to some extent, because fewer developers feel motivated — artistically, financially, or both — to create well-crafted idiomatic native apps exclusively for Apple’s platforms.

Quoting Kyle Kingsbury

15th April 2026 I think we will see some people employed (though perhaps not explicitly) as meat shields: people who are accountable for ML systems under their supervision. The accountability may be purely internal, as when Meta hires human beings to review the decisions of automated moderation systems. It may be external, as when lawyers are penalized for submitting LLM lies to the court. It may involve formalized responsibility, like a Data Protection Officer. It may be convenient for a company to have third-party subcontractors, like Buscaglia, who can be thrown under the bus when the system as a whole misbehaves. — Kyle Kingsbury, The Future of Everything is Lies, I Guess: New Jobs Recent articles - DeepSeek V4 - almost on the frontier, a fraction of the price - 24th April 2026 - Extract PDF text in your browser…

Trusted access for the next era of cyber defense

14th April 2026 - Link Blog Trusted access for the next era of cyber defense (via) OpenAI's answer to Claude Mythos appears to be a new model called GPT-5.4-Cyber: In preparation for increasingly more capable models from OpenAI over the next few months, we are fine-tuning our models specifically to enable defensive cybersecurity use cases, starting today with a variant of GPT‑5.4 trained to be cyber-permissive: GPT‑5.4‑Cyber. They're also extending a program they launched in February (which I had missed) called Trusted Access for Cyber, where users can verify their identity (via a photo of a government-issued ID processed by Persona) to gain "reduced friction" access to OpenAI's models for cybersecurity work. Honestly, this OpenAI announcement is difficult to follow. Unsurprisingly they don't mention Anthropic at all, but much of the piece emphasizes their many years of existing cybersecurity work…

Quoting Bryan Cantrill

13th April 2026 The problem is that LLMs inherently lack the virtue of laziness. Work costs nothing to an LLM. LLMs do not feel a need to optimize for their own (or anyone's) future time, and will happily dump more and more onto a layercake of garbage. Left unchecked, LLMs will make systems larger, not better — appealing to perverse vanity metrics, perhaps, but at the cost of everything that matters. As such, LLMs highlight how essential our human laziness is: our finite time forces us to develop crisp abstractions in part because we don't want to waste our (human!) time on the consequences of clunky ones. — Bryan Cantrill, The peril of laziness lost Recent articles - DeepSeek V4 - almost on the frontier, a fraction of the price - 24th April 2026 - Extract PDF text in your…

Meta is laying off 10 percent of its staff

Meta is planning to layoff around 10 percent of employees in May, according to a memo from the company’s chief people officer, Janelle Gale, published by Bloomberg. That means approximately 8,000 people will see their jobs cut. Meta will also be closing around 6,000 open roles, according to Gale. Meta is laying off 10 percent of its staff Meta is making the cuts to help ‘offset the other investments we’re making.’ Meta is making the cuts to help ‘offset the other investments we’re making.’ The cuts follow Meta’s significant investments in AI, including spending huge sums to hire top talent and build data centers.

The increase is to…

Anthropic’s Mythos breach was humiliating

Anthropic’s tightly controlled rollout of Claude Mythos has taken an awkward turn. After spending weeks insisting the AI model is so capable at cybersecurity that it is too dangerous to release publicly, it appears the model fell into the wrong hands anyway. Anthropic’s Mythos breach was humiliating There’s no good excuse for letting hackers into an AI model too dangerous for public release. There’s no good excuse for letting hackers into an AI model too dangerous for public release. According to Bloomberg, a “small group of unauthorized users” has had access to Mythos — whose existence was first revealed in a leak — since the day Anthropic announced plans to offer it to a select group of companies for testing. Anthropic says it is investigating. That’s a rough look for a company that has built its brand on taking AI…

Anthropic’s most dangerous AI model just fell into the wrong hands

Anthropic’s Mythos AI model, a powerful cybersecurity tool that the company said could be dangerous in the wrong hands, has been accessed by a “small group of unauthorized users,” Bloomberg reports. An unnamed member of the group, identified only as “a third-party contractor for Anthropic,” told the publication that members of a private online forum got into Mythos via a mix of tactics, utilizing the contractor’s access and “commonly used internet sleuthing tools.” Anthropic’s most dangerous AI model just fell into the wrong hands A Discord group has had access to the Mythos model for two weeks.

OpenAI Executive Kevin Weil Is Leaving the Company

Kevin Weil, OpenAI’s former chief product officer who was recently tapped to build a new AI workspace for scientists, Prism, is leaving the company, WIRED has confirmed. Weil was previously an early executive leading product at Instagram. “Today is my last day at OpenAI, as OpenAI for Science is being decentralized into other research teams,” Weil said in a social media post on Friday, shortly after WIRED reported his departure. “It’s been a mind-expanding two years, from Chief Product Officer to joining the research team and starting OpenAI for Science.” Weil did not immediately respond to a request for comment from WIRED. OpenAI is also sunsetting Prism, which the company launched as a web app in January to give scientists a better way to work with AI. The company is folding the roughly 10-person team behind it under OpenAI’s head…
