KhuyenTran16 · x · 2026-11-12
PydanticAI released v2.57.0 with Harness ApprovalReviewer: a second model screens approval-required tool calls, auto-clearing harmless ones before they reach humans — combating approval fatigue that trains people to blindly click Approve. The release also adds a MetaProvider for Meta Muse models, MCP Apps tool-result forwarding to AG-UI/Vercel AI frontends, Skills invocation controls, and session-core-managed realtime history for GPT-Live/Gemini Live.
