Microsoft Research's 'Fork-and-Flush' method reduces idea basins and improves long-running AI agents

Microsoft Research shows that growing chat context can trap autonomous 'autoresearch' agents in suboptimal 'idea basins' during long-running tasks. Their Fork-and-Flush approach forks agents into parallel branches that inherit workspaces but flush chat history; across 13 tasks (using GPT-5.6-terra and GPT-5.5 via GitHub Copilot CLI) it raised the min-max-normalized average score to 0.78 versus 0.47 for single runs, improving consistency as well.

GitHub rewrote the Copilot agent runtime in Rust with Copilot agents

GitHub migrated the Copilot agent runtime from a TypeScript/Node.js/V8 implementation to over 800,000 lines of production Rust. Most of the Rust code was authored by AI agents via the GitHub Copilot app and CLI across 128 pull requests; the migration shipped incrementally, reportedly improving runtime performance by orders of magnitude and reducing startup and memory overhead for many Microsoft/GitHub products that share the runtime via the Copilot SDK.
