Microsoft agentically ports Copilot runtime to Rust for $120K
The Rust compiler remains unperturbed by the antics of the LLM
Microsoft has recently rewritten the runtime for its popular AI-powered coding assistant, GitHub Copilot, using Rust. This transition was largely automated by AI agents, with the project costing around $120,000 and spanning 14.5 weeks. The shift from TypeScript to Rust resulted in a significant performance improvement, with the Rust implementation being 15.9 times faster than the original TypeScript runtime.
The rewritten runtime is now integrated into various Microsoft products, including VS Code, the GitHub Copilot CLI, and several Microsoft Office applications. Microsoft Distinguished Engineer Stephen Toub emphasized that while Rust's performance benefits are noteworthy, there are hidden challenges in using the language, as the compiler does not guarantee the correctness of the code.
