MAI-Code-1-Flash

Full Guide

MAI-Code-1-Flash is a product or capability from Microsoft documented by first-party sources. GitHub made Microsoft’s MAI-Code-1-Flash coding model generally available to Copilot Business and Copilot Enterprise on June 26, 2026.

What it does

Microsoft introduced MAI-Code-1-Flash on June 2 as an in-house model designed for fast, adaptive coding assistance in GitHub Copilot. The June 26 enterprise release requires plan administrators to enable the MAI-Code-1-Flash policy before users can select it, and GitHub lists the model for fast, iterative coding workflows.

Availability and pricing

The model is generally available for Copilot Business and Enterprise and is billed at provider list pricing under GitHub’s usage-based billing. Access depends on plan, administrator policy, supported Copilot surfaces, and current model availability; GitHub’s model and pricing documentation should be checked before rollout.

Who it is for

Developers, engineering teams, Copilot administrators, and enterprise users comparing fast coding models for iterative or high-volume workflows.

What teams should review

Model behavior can change with new checkpoints, Microsoft and GitHub publish the performance claims, and teams still need to compare quality, latency, usage cost, security, and repository fit on their own tasks.
