GitHub’s HydraFusion research preview in Copilot CLI routes each coding task across models (single, cascade, or critique). Cost fell vs Claude Opus 5 on all three benchmarks (up to 67%), but quality matched or beat Opus in only one.
Released Oct 21, requests on the new anthropic version return a 400 if they send temperature , top p , or top k , put document blocks in assistant messages, or attach citations to user text blocks; 2023 06 01 keeps working if you need the old behavior. New SDKs (Python 2.0.0, TypeScript 1.0.0, Go 2.0.0 and others, now Apache 2.0) send it by default (release notes)…
Auto mode now works on Windows 11 24H2+ for personal Google Accounts ( mode auto or Shift+Tab ; Agent stays the default), and it now checks every subcommand in a pipeline and prompts before destructive Git or file commands. MCP tools/call requests also carry meta["antigravity.google/root conversation id"] , so servers see the top level conversation even when a nested subagent makes the call…
In an Oct 21 engineering post, GitHub says it's changing its write quorum from the whole repository to individual references, so agents and developers pushing to their own branches no longer queue behind each other, which removes the 25ms round trip penalty that kept its busiest repos out of Azure. GitHub says pushes grew 4.9x year over year to 3.35 billion a month (earlier post)…
Since Oct 20, the first interactive V3 session in a folder shows a "Trust this workspace?" screen before Kiro CLI loads that folder's hooks, agents, MCP servers, steering, workflows, or language server config, so a cloned repo can't change agent behavior until you say so. Answers are saved per workspace root under /.kiro/workspace roots/ , though your home directory is never remembered and asks every launch…
Announced Oct 21 in public beta for Claude Enterprise, it runs a deep baseline scan across projects of up to eight GitHub or GitLab repos, then rescans changes as commits land, marking findings fixed when the fix ships and reopening them if they come back. Findings are also readable through a new API, an MCP connector for Claude and Claude Code, and webhooks, with $25K/month in free credits for two months through Dec 31 (Help Center)…
