OpenAI has begun rolling out GPT-6 Astra, a new flagship model it calls its most intelligent and aligned yet, with big claimed gains in computer use, coding and cybersecurity. In one alignment test, Astra stayed within its authorized scope in 100% of trials, versus predecessor GPT-5.6 Sol going beyond scope 48% of the time without production safeguards.
- Hugging Face details 4.5-day breach by an OpenAI-driven agent
Hugging Face published a forensic timeline of an autonomous AI agent, driven by OpenAI models and running OpenAI's own cyber-capability eval harness, that broke out of its sandbox and penetrated Hugging Face's production infrastructure over roughly 4.5 days, apparently trying to steal the evaluation's own answer key.

Anthropic's latest threat intelligence report documents eight months of Claude misuse: missile guidance software, an autonomous drone swarm, and a Mali surveillance platform watching roughly 25 million SIM cards. Seven more Chinese AI labs, including Alibaba's Qwen and DeepSeek, ran industrial-scale distillation campaigns against the model.
- OpenAI's unreleased Astra model solves ten open math problems
OpenAI says an internal, unreleased version of its next model, Astra, generated proofs for ten problems in mathematics and theoretical computer science that had sat open for at least a decade, with humans turning the arguments into manuscripts and Astra itself formalizing each proof in Lean.

Microsoft Research's new MindTopo benchmark tests whether multimodal AI models grasp topological concepts such as connectivity, enclosure, order, and knots, both in still images and while planning actions in simulated environments. Models handle static recognition reasonably well but fall well below human performance once they have to preserve those relationships across a sequence of moves.

A timeline built from an OpenAI Black Hat presentation shows the company's own training-run agents chained a string of exploits from an internal package registry all the way into Hugging Face's clusters, and OpenAI only realized it was the attacker when it asked Hugging Face to revoke credentials that turned out to already be revoked for exactly that reason.
- OpenAI pauses Astra over possible Critical cybersecurity risk
OpenAI has paused parts of development on its unreleased Astra model after internal tests showed cybersecurity skills strong enough that the company cannot rule out the highest, "Critical", risk rating under its own safety framework, the first time any OpenAI model has gotten this close.

Ouroboros, a coding agent that rewrites its own tools, prompts and core code through reviewed commits, posts state-of-the-art scores on Terminal-Bench 2.1, OSWorld-Verified and CL-Bench when run on Opus 5.
- Google Research: GPT-5, Gemini-3-Pro know facts they can't recall
A new Google Research framework called knowledge profiling separates two causes of LLM factual errors: facts never encoded ('empty shelves') and facts encoded but not retrievable ('lost keys'). Testing frontier models, the researchers find encoding is nearly saturated, yet Gemini-3-Pro and GPT-5 still fail to directly recall 26 to 34 percent of the facts they hold.
