There's a huge price difference between o3-mini and o1 ($4.40 vs $60 per million output tokens), what trade-offs in performance would justify such a large price gap?

Are there specific use cases where o1's higher cost is justified anymore?

How would you rate it against Claude ? Didn’t test it yet, but o1 pro didn’t perform as good

I've been trying out o3 mini in Cursor today, it seems "smarter" but overall tends to overthink things and if it's not provided with perfect context it's prone to hallucinate. Overall I prefer Sonnet still. It has a certain magic of always making reasonable assumptions and finding simple solutions.

As n occasions user and fan of Cursor, it would be good if they could explain what the models are and why the different models exist.

There’s no obvious answer of why one should switch to any of them!
