    Interesting work, and thanks for describing how your router works internally. It's definitely a fascinating subject. How would you say this compares to Cursor's auto mode?

      And similarly, Copilot’s Auto mode?

        I haven't tried it as recently but last time I checked they only route once per session (or subagent). Imo this is basically impossible to do correctly. Consider the case where you start with one prompt "rewrite this in rust". Trivial in a 1 day old repo, extremely difficult in e.g. the VSCode repo!

      Absolutely!

      Conceptually very similar to Cursor's auto mode. The key distinctions are:

      - We plug into any harness (e.g. Claude Code, Codex, OpenCode, Pi)

      - We aren't incentivized to route to our own model, we're incentivized to route to the best model whatever it may be
