Microsoft has formally declared that MAI-Code-1.1-Flash has commenced its production phase within GitHub Copilot. When compared to the 1.0 iteration, which was unveiled in June, this latest model boasts notable advancements in code quality, inference speed, and cost-effectiveness. Performance-wise, it has demonstrated a 22% upswing in the GitHub Copilot CLI's Terminal-Bench 2.1 benchmark evaluation, along with a 15% boost in tasks related to .NET. Within real-world production settings, the rate of code adoption has surged by 4%, while the user retention rate has climbed by 9%. In terms of operational efficiency, the model's Token streaming output velocity has accelerated by 25%, the Token count necessary for accomplishing identical tasks has diminished by 25%, and inference expenses have been slashed to a mere quarter of those associated with the 1.0 version. Presently, MAI-Code-1.1-Flash is being progressively deployed across a range of GitHub Copilot services, encompassing VS Code, Visual Studio, and beyond.
