Anthropic released a developer guide for teams moving to Claude Sonnet 5.5. It lays out five breaking changes and says the old setting for turning thinking off and forced tool calls now return 400 errors.
Anthropic released Sonnet 5.5, the second model in the Claude 5.5 family. It generates output more than 30% faster than Sonnet 5, costs up to 30% less per task, and comes close to Opus 5.5 on several benchmarks.
Nvidia has released the Open Agent Safety Platform, which pairs OpenShell, a runtime that draws an agent's boundary on the CPU, with Sentry, a watchdog that monitors agents from a DPU. More than 100 organizations, including Anthropic, SpaceXAI and Salesforce, are taking part.
In an interview, NASA creative director David Rager cited brand trust as the reason the agency does not use AI imagery. A 67-year brand history, from the 1959 meatball to the 1975 worm, carries that trust principle into the AI era.
After OpenAI fixed an image-encoding bug in GPT-6 Sol and Luna, Luna's visual grounding score rose from 28.8% to 60.0%. OpenAI advised developers who use image inputs to rerun their evaluations.

Codex web, the API, the CLI and the VS Code extension all went down at once in a full outage. OpenAI restored usage limits for every paid user 13 minutes after recovery, but the cause has not been disclosed.

The official Claude account gathered things people built with Opus 5.5 into a thread. From a lens lab to a dental CT viewer, every piece was drawn in code.
When it hits the 5-hour limit, Claude Code no longer stops mid-edit; it tidies up the work until it reaches a good place to pause. The allowance it uses to finish comes out of the weekly limit.
The federal appeals court in Washington, D.C., ruled 2-1 that excluding Claude from the supply chain was lawful. The dissent argued that the majority read a single word in the statute, manipulate, far too broadly.
At the site of the Bundibugyo Ebola outbreak in the Democratic Republic of the Congo, the WHO Regional Office for Africa, CEPI and the DRC's National Institute of Biomedical Research are using Claude. A situation report that took a full day now takes under an hour, and in a fight against a disease with no vaccine, what does that time change?
