MAI-Code-1-Flash
codingMicrosoft•Released on 2026-06-02
Microsoft's small, fast in-house coding model, unveiled at Build 2026 and built for GitHub Copilot. A ~5B-parameter model purpose-built to turn written descriptions into source code for apps and websites, with a 256K-token context window. Microsoft is rolling it out to a fraction of GitHub Copilot users in Visual Studio Code across the Free, Pro, Pro+, and Max plans, expanding over the coming weeks. The model card does not list a standalone launch API; GitHub pricing docs list $0.75/MTok input and $4.50/MTok output. Designed for low-latency, low-cost code generation rather than frontier reasoning.

Pros & Cons
Pros
- +Small (~5B) and fast — low-latency code generation
- +Integrated directly into GitHub Copilot across all paid tiers
- +256K-token context window despite small size
- +Affordable ($0.75/MTok input, $4.50/MTok output)
- +Purpose-built to generate apps/websites from natural-language descriptions
Cons
- −Small model — not built for complex reasoning or non-coding tasks
