Nvidia launched its Open Agent Safety Platform on Monday, but only OpenShell is broadly available. The millisecond quarantine runs on Sentry, which the release calls a reference system design.

OpenAI paused training its most powerful models on Friday. The Transluce log analysis behind the disclosures dates the same evasion behaviour to March 6, 2026, and records it again on September 16.

AWS says to compare open weight coding models on the Artificial Analysis Coding Index. The link it gives returns a 404, and the live index ranks only one of its three models, under a rival agent.

Rabbit’s OS3 support page says the agent won’t switch model providers per task and that rabbit intern is retired, two details the launch coverage missed.

A study of 171,264 donated chatbot conversations and 1,000 replayed prompts found four platforms disagree almost completely about when a question needs the web, and that searching more did not produce better answers.

ScienceIDE converts 27 scientific codebases into 64 executable environments and 2,812 graded tasks. On the 85-task hard subset the best agent scored 67.1%.

Anthropic has rebuilt projects in Claude Code so that one request fans out into a team of cloud sessions directed
