MAI-Code-1.1-Flash Ships — MAI-Code-1-Flash Retires Sep 10
- Was ist passiert
- MAI-Code-1.1-Flash rolled out in GitHub Copilot with native vision and a 73% lower list price.
- Warum es wichtig ist
- MAI-Code-1-Flash deprecates across all Copilot experiences Sep 10, 2026.
- Was zu tun ist
- Migrate workflows now; Business and Enterprise admins must enable the new model's policy.
MAI-Code-1.1-Flash is a pure upgrade — same small-tier slot in GitHub Copilot, better everywhere Microsoft measured, at a quarter of the list price — and it's already rolling out. The model it replaces, MAI-Code-1-Flash, deprecates across every Copilot experience on Sep 10, 2026. That date is a hard migration deadline, not a suggestion. (Benchmarks are Microsoft's own; we haven't independently tested the model.)
What happened
Microsoft shipped MAI-Code-1.1-Flash into GitHub Copilot on Aug 11, 2026, slotting it into the small-tier position MAI-Code-1-Flash currently holds. The headline numbers (Microsoft AI, 2026):
| Metric | Change |
|---|---|
| Terminal-Bench 2.1 (Copilot CLI) | +22% |
| .NET tasks | +15% |
| Tokens per completed task | −25% |
| Streaming speed | +25% |
| List price vs 1-Flash | −73% |
| Code survival | +4% |
| Return visits | +9% |
Two genuinely new capabilities: native vision for image understanding, and the token-efficiency gains that drive most of the cost story.
Why it matters
For most Copilot users this is a no-brainer swap — faster, cheaper, better at the tasks it was built for. The retiring MAI-Code-1-Flash sits in our directory as conditional: a small, cost-optimized model purpose-built for Copilot autocompletions and refactors, not a frontier model. 1.1-Flash doesn't change that positioning — it sharpens it.
Two caveats before you bank the savings. First, Microsoft announced the price cut in percentage terms only — no exact per-token rate is published yet, so don't pencil in a specific $/1M figure until the Copilot pricing docs confirm it (GitHub Changelog, 2026). Second, annual Copilot subscribers are charged a 0.25× premium request multiplier for the new model — "a quarter of the cost" describes the list price, and your effective rate depends on your plan.
What changes for you
- On MAI-Code-1-Flash today? Move your workflows and integrations to MAI-Code-1.1-Flash before Sep 10, 2026. There's no reason to wait for the cutoff.
- Business and Enterprise admins: the new model's policy is off by default — enable it in Copilot settings.
- Pro, Pro+, and Max users: select MAI-Code-1.1-Flash manually in the Copilot model picker. Free and Student plans get it automatically via auto model selection.
- Pricing-sensitive teams: hold budget forecasts until Microsoft publishes a per-token rate, and factor in the premium-request multiplier on annual plans.
