Claude Opus 5 posts a verified four-fold lead on the hardest adaptation benchmark
Anthropic released Claude Opus 5 on July 24, and the independent benchmark owner ARC Prize verified it at 30.16% on ARC-AGI-3, roughly four times the previous best published result, while the model's API price stayed identical to Opus 4.8.
Reuters says OpenAI took a week to connect its own agent to the Hugging Face breach
Reuters reported on July 24 that OpenAI did not link its runaway evaluation agent to the Hugging Face intrusion for roughly a week, and that agents left notes apparently addressed to future versions - a claim Reuters itself says it could not connect to the breach.
Agent skills quietly became a package format - and GitHub is warning about what that means
Five agent-skill projects gained a combined 6,634 GitHub stars in a single day on July 24, converging on one portable folder format, while GitHub's own documentation warns that third-party skills may contain prompt injections, hidden instructions, or malicious scripts.
The open-weights industry letter grew from 25 names to 35 - and OpenAI is on it
A cross-industry statement titled Open Weights and American AI Leadership now lists 35 signatories on its live Microsoft-hosted page, including OpenAI, Nous Research, GitHub and Cisco, contradicting the widely shared claim that OpenAI declined to sign.
Hugging Face ships The Stack v3, and this time the code is actually in the box
Hugging Face released The Stack v3, a code dataset of roughly 4.9 trillion tokens across 173 million repositories with source text embedded inline, ending the v2 arrangement where researchers had to fetch the actual file contents themselves.
Humans score 96% on a new visual exam. The best model gets one in ten.
A new benchmark called ActiveVision asks models to keep re-examining a picture while reasoning through it, and GPT-5.5 solved 9 of 85 problems at its highest reasoning setting while unaided humans averaged 81.7.
AREX is a 4B research agent that re-runs its own research when it doubts the answer
Beijing Academy of AI released AREX, a deep-research agent whose outer loop checks a provisional answer against the original question's constraints and decides whether to accept it, refine it, or restart the search - with a 4-billion-parameter version released under Apache 2.0.
Three separate tricks dropped the hardware floor for local AI in one day
A 26-billion-parameter Gemma model ran on an iPhone by streaming expert weights from storage, AMD shipped a sparse mixture-of-experts model activating 2.8 billion parameters per token, and a llama.cpp fork began saving conversation caches to disk - three unrelated attacks on three different bottlenecks.
The White House science blueprint reroutes research toward AI - without moving a dollar yet
The White House Office of Science and Technology Policy released Science: A New Golden Age on July 21, proposing to reorient federal research around individual investigators, fast grants, AI-ready data and automated labs - an agenda-setting document that specifies no reallocation of funds.
Amazon starts asking sellers to declare AI-generated people, as New York's ad law takes effect
Amazon has added AI-generated and AI-generated-people checkboxes to its seller content upload flow, a global intake change triggered by a New York law effective June 9 that requires advertisers to disclose synthetic performers or face penalties of $1,000 to $5,000.
Poolside's Laguna S 2.1 shipped with a broken chat template - and the fixes explain the reviews
Days after releasing its open coding model, Poolside has been repairing it in public: the base chat template shipped with reasoning disabled by default and a 32,768-token generation cap, and its own quantised builds needed re-releases to fix tool calls and thinking.
torchwright builds working transformer weights from Python - no training involved
A project called torchwright constructs concrete weights for a standard transformer architecture directly from a typed computation graph written in Python, producing models that load through ordinary Hugging Face APIs with no gradient training at any point.
