I've been using Gemini 3.1 Pro, mostly because I'd gotten used to Gemini in general, but it seems to be a relatively mediocre coder at best; it struggles, for example, on a ~600 LoC JS file, introducing approximately one new bug for every fixed one. That feels really unacceptable for a frontier model today, judging by all the praise I've been reading for Claude Code and Codex.
If you've tried a few different frontier LLMs for coding recently, do you have any strong recommendations?
