Following a weighted analysis balancing human opinion and backend performance, a new leaderboard was generated, with Sonnet 46 and Gemini 3 Pro leading, followed by GPT 5.5. Recommendations were made per task: GPT 5.5 for PRDs, Sonnet 46 for prototyping and conversational tasks, and Opus 48/Sonnet 5 for codebases.
“At the top of the list, Sonnet 46. Who would have thunk? And Gemini 3 Pro. Followed by what I think is my favorite 55. And at the bottom, poor brand new Sonnet 5 and really expensive 48.”
“Model by task. If you're writing a PRD, use GPT 5.5 because it will give you something comprehensive and clear. If you are prototyping, guess what? Sonnet 46. Pretty good. And if you want to chit chat with a model, again, Sonnet 46 has good vibes.”
