Enterprise DNA reported on Microsoft's unveiling of MAI-Code-1-Flash at Build 2026 on June 2, 2026, describing it as Microsoft's first coding AI model built entirely in-house without OpenAI's technology or data. The article details that it is a 5-billion-parameter coding model trained directly on GitHub Copilot's produ The same article reports that Microsoft is rolling out MAI-Code-1-Flash inside GitHub Copilot's model picker in Visual Studio Code, including the default auto-picker, meaning most Copilot users will get the new model automatically on their next task. The piece frames this as a strategic signal of Microsoft building in-

Microsoft's AI Superintelligence team introduced MAI-Code-1-Flash on June 2, 2026 as a coding model built for fast, efficient, everyday developer workflows. The model was trained from scratch on clean, traceable, enterprise-grade data without distillation from third-party models, and is rolling out to GitHub Copilot in The launch post emphasizes that MAI-Code-1-Flash was designed to maximize value per token through adaptive solution length control, allowing it to deliver useful output sooner on simpler tasks while reserving deeper reasoning for harder problems. During training, checkpoints were evaluated on core software-engineering

GitHub has officially deprecated MAI-Code-1-Flash across all Copilot experiences as of September 10, 2026, according to a first-party changelog entry on github.blog. The deprecation covers Copilot Chat, inline edits, ask and agent modes, and code completions, meaning the model is no longer a supported option for develo GitHub instructs affected customers to migrate to MAI-Code-1.1-Flash, which is the suggested alternative explicitly named in the changelog. Copilot Enterprise administrators may need to enable access to the replacement through their model policies in Copilot settings, after which the successor appears in the Copilot Ch

GitHub announced in its official Changelog that MAI-Code-1-Flash, Microsoft's latest small-tier coding model, is rolling out in GitHub Copilot starting with VS Code. The post explicitly names the model and frames it as Microsoft's first in a new wave of purpose-built coding models, designed and tuned specifically for G According to the same Changelog entry, MAI-Code-1-Flash availability is beginning across Copilot Free, Student, Pro, Pro+, and Max plans (with Student added on June 5, 2026 via editor's note), starting with a limited set of users and expanding gradually over the coming weeks.
