ChatGPT thinking models are very good; the instant model is bad. Gemini is always desperate to find an answer, and will give you one no matter what.

I have access to the ChatGPT account of my boss and it is unusable sycophancy slop, horrible to read because every information is buried under endless emojis and the like. And it is almost indistinguishable if the LLM is wrong or right, every answer looks the same, often with a "my final answer" at the end. It's a mess.

I'm using Claude Opus 4.6 and it is much calmer, or "professional" in tone and much more information and almost no fluff.
