Six models, gone Sept 1
Copilot removes Gemini 3.1 Pro, Claude Opus 4.5 and 4.6, Claude Sonnet 4.5 and 4.6, and Raptor Mini. Mapped swaps: Opus → 4.7/4.8/5, Sonnet → Sonnet 5, Gemini 3.1 Pro → 3.6 Flash, Raptor Mini → MAI-Code-1-Flash.
Annual plans keep a Sonnet
Individual subscribers on annual plans keep Sonnet 4.6, so a Sonnet option survives. Enterprise admins must enable the replacements in Copilot settings before the cutover, then confirm they appear in the VS Code and github.com model pickers.
Grok 4.6 is the cheap agent pick
Live in Copilot and Cursor since Aug 12: a 500K-token window at $2/$6 per million tokens, tuned to self-verify across long agent runs — roughly half the price of comparable frontier models.
Gemini 3.7 Flash hits GA
Google's coding-and-agent workhorse is generally available at an introductory rate through Dec 31, a ready drop-in for retired Gemini slots. Google cites gains on software engineering and agentic workflows.
Elsewhere: Vercel deploys without stored keys
Vercel for Platforms now takes a temporary GitHub token at deploy time — encrypted and never retained — so multi-tenant hosts can stop storing long-lived credentials.
