Copilot Coding Agent Now Starts Work 50% Faster
GitHub has cut the Copilot coding agent's startup time in half. Whether you're assigning an issue directly to Copilot, spinning it up from the Agents tab, or tagging @copilot in a pull request comment, the agent now reaches its cloud-based dev environment, runs tests, and pushes its first changes significantly sooner than before. GitHub frames the improvement as creating a "faster feedback loop" for teams that have started delegating real tasks to the agent — and that framing is exactly right.
Startup latency has consistently been one of the most-cited friction points in early agentic coding workflows. When delegation feels like waiting, developers default back to doing the work themselves. A 50% reduction in spin-up time is a meaningful threshold shift — it's the difference between an agent that feels like a tool and one that feels like a teammate. For the broader AI coding landscape, this also sets a new baseline expectation. As OpenAI continues building out Codex's own agent capabilities, users will now arrive with a concrete benchmark in mind for what "fast enough" actually means in a production agentic loop.
