OpenAI publishes security guidelines for frontier RL training runs

Dynamo-Triton now supports an end-to-end HSTU generative recommender workflow via NVIDIA's recsys-examples repo, combining PyTorch AOTI, FlexKV KV caching, and NV embedding cache. At batch size 8 on an RTX PRO 6000 Blackwell Workstation GPU, it hit up to 4.47x speedup for the three-layer HSTU model and 5.93x for the eight-layer model at 100% KV-cache hit rate.

METR President Chris Painter testified September 30, 2026 before a Senate Homeland Security subcommittee hearing titled "Rogue AI: Securing the Homeland Against AI Agent Attacks."

Gemini 4 Argon is Google's new frontier model, rolling out to trusted testers via the Fairwind Program before wider release. It scores 77.9% on DeepSWE v1.1 and 77.5% on AutomationBench-AA, and is priced at $2/$10 per million input/output tokens during introductory pricing.

At a MAHA event with VP JD Vance, Health Secretary Robert F. Kennedy Jr. said AI is "better informed than any doctor in the country" and urged Americans to use it for second opinions. Ars Technica tested his claims: Gemini said masks do reduce respiratory disease spread.

Framework's DIY Edition desktop with AMD Ryzen AI Max 400 Series and 192GB memory is now available for preorder. The 192GB unified memory configuration targets local LLM workloads.

NVIDIA added cuObject to xio-sig alongside cuFile, in partnership with Google Cloud and Microsoft, and made cuObject client and server libraries generally available. The new SCADA Server SDK lets storage providers build servers that answer GPU-initiated requests; IBM showed a prototype integrating SCADA with IBM Storage Scale.
