Xiaomi released MiMo-V2.6-Pro and Flash as open weights (MIT) plus a Distill-Qwen-9B research model, claiming Pro leads open models on Artificial Analysis at 46 while still trailing Claude Fable 5.1 and GPT-6 Astra. The drop also includes 7,000+ RL task environments, an end-to-end RL framework, and mini-harnesses for multi-harness agent training.
Claude Opus 5.5 is rolling out in GitHub Copilot for Pro+, Max, Business, and Enterprise across VS Code, JetBrains, Copilot CLI, the coding agent, and more. Early tests matched Opus 5 on task resolution with fewer steps and tokens; Enterprise/Business admins can gate it via model policy…
Anthropic says nearly 950 Claude agents spent 21 hours and 210 million tokens scanning DNA data before flagging a previously uncharacterized bacteriophage enzyme system for human review. The company compares the find to CRISPR machinery but says practical uses are still unclear; it’s the first result from its new wet lab…
Appwrite’s official Codex/ChatGPT plugin now ships a hosted MCP at https://mcp.appwrite.io/ with OAuth (no local API keys) plus 13 skills for SDKs, CLI, Sites, and Functions. Install from the ChatGPT desktop Plugins sidebar or Codex CLI /plugins in the OpenAI Curated marketplace…

It’s off by default; turn it on in project settings or with /sandbox on , and sessions fail closed if the OS can’t enforce the policy…
Claude Code’s AGENTS.md fallback sat behind a remote feature flag that failed when telemetry or nonessential traffic was disabled, so the local file was skipped with no warning. An Anthropic engineer said the gate was a rollout kill switch and is fixed in v2.1.281…
