Confusing take - Gemini 2.5 is probably the best general purpose coding model right now, and before that it was Sonnet 3.5. (Maybe 3.7 if you can get it to be less reward-hacky.) OpenAI hasn't had the best coding model for... coming up on a year, now? (o1-pro probably "outperformed" Sonnet 3.5 but you'd be waiting 10 minutes for a response, so.)
