Keen to try this out. Composer 2 is a reliable workhorse and much cheaper than the frontier models. Yes it may be based on Kimi, but it is good, really good. My workflow:
- If its simple/obvious - give it to composee 2 immediately
- If its complex either work on a plan with ChatGPT (pro mode is insane) or create a plan with GPT 5.5 or GPT 5.3 codex, and then implement with composer
I continue to be surprised at how good Anthropic are at getting people to promote an agent harness that doesn't have a decent UI. Cursor has as good (arguably better) coding agent AND a decent UI. Yes its forked from VS Code, but who cares it's good. I tried Zed the other day, but can't really see the advantage - on a decent mac performance is the same, and Cursor is more polished. Anthropic may be winning the PR battle but I think cursor is laughing all the way to the bank.
Presumably the RL for coding is better as that's literally what Composer is. I also assume Cursor subsidizes it to make people want to use it more, but I think the age of AI API wrappers is over as the AI companies themselves can just subsidize much more compute than what a wrapper could pay for, like Claude Code or Codex limits being way higher than their monthly price would imply.
