GitHub Copilot retires Gemini, Kimi and Claude models on 2 October, and one replacement costs three times as much
Read the full description of this diagram
Diagram mapping each model GitHub Copilot retires on 2 October 2026 to its named replacement, with input rates per million tokens from our own table beside each row: Gemini 3.5 Flash at $1.50 to Gemini 3.8 Flash at $0.75, marked the rate halves; Kimi K2.7 Code at $0.95 to Kimi K3 at $3.00, marked the rate triples; Gemini 3.6 Flash to Gemini 3.8 Flash and Claude Opus 4.7 to Claude Opus 5 at $5.00, with each retired model shown as no row on our table and its direction left unpriced. Below, a timeline runs from the changelog on 3 September 2026 to the retirement date of 2 October 2026 across every Copilot surface, with a box between them for the administrator who must enable the replacements in model policy on Business and Enterprise plans, or the picker simply empties.
Google's Gemini 3.5 Flash and 3.6 Flash, Moonshot's Kimi K2.7 Code and Anthropic's Claude Opus 4.7 go, and GitHub's reference still lists them as available.
