Anecdotally, I find Composer 2.5 to be useless. I do use light LLMs like Claude Haiku and some of Cursor's older free models, but Composer is negative productivity for me.
Same here, maybe I'm underusing it a bit, because for anything that is a bit more complex i tend to err on the safe side and go with anthropic, but i wonder if thats just a placebo effect because i pay more for it.
I do feel that they've really upped their game with composer this year though.
