Agent harness comparison

With the same model, GitHub Copilot CLI and Claude Code showed no significant difference. Model choice matters more.

Area: Developer tools. Status: GA. Developer relevance: medium. Airtime: 1 min across 1 video.

Status evidence

  • Nothing said about status; launch event convention: generally available unless stated otherwise.

Where they talk about it

Quotes

  • 4:57 "So the choice of models probably matter more than the choice of agent harness at least using our data set." - Design guidance: pick the model carefully, the harness matters less.

Caveats mentioned

  • Conclusion applies to the BC-Bench data set

Documented features match

  • No documented item matched. BC-Bench not documented

Docs checked on 2026-10-02: the match is against Microsoft's what's new pages for the wave as they were on that date. Microsoft keeps filling the documentation, so "no documented item" can go stale. The wider product documentation on learn.microsoft.com was searched for this feature on the same date; the feature's data lists an article when one was found.
