On 3 September 2026 GitHub said it will retire Gemini 3.5 Flash, Gemini 3.6 Flash, Kimi K2.7 Code and Claude Opus 4.7 from every GitHub Copilot surface on 2 October 2026, naming Gemini 3.8 Flash, Kimi K3 and Claude Opus 5 as the replacements. The changelog lists Copilot Chat, inline edits, ask and agent modes and code completions as the surfaces affected, and tells Business and Enterprise administrators they may have to enable the replacement models in their own model policies first. Read on 6 September 2026, GitHub's supported-models reference still listed all four as generally available and its retirement-history table still had no row for any of them. Sources. GitHub Copilot changelog, 3 September 2026, where the retiring models and the retirement date are named: https://github.blog/changelog/2026-09-03-upcoming-deprecation-of-selected-github-copilot-models (read 6 Sep 2026) GitHub's supported-models reference, including its model retirement history table: https://docs.github.com/copilot/reference/ai-models/supported-models (read 6 Sep 2026) Why it matters. A suggested replacement is not a like-for-like swap, and our own price table says so in both directions. Gemini 3.5 Flash sits at $1.50 per million input tokens and Gemini 3.8 Flash at $0.75, both checked on 5 September 2026, so that substitution halves the rate for the rest of 2026 only: the $0.75 is promotional and Google's pricing page returns it to $1.50 on 1 January 2027, which leaves the Gemini swap costing what the model it replaced costs today. Kimi K2.7 Code sits at $0.95 and Kimi K3 at $3.00 on the same check, so that one triples it. If Copilot is the only place you meet these models the swap costs you nothing, because the seat price does not itemise them. If you also call them directly, the retirement is a nudge toward a rate card you did not choose, and it is worth pricing your own traffic before 2 October rather than after.
