o3:

The bad news: it's extremely expensive.
The good news: cheaper than o1 while being much more performant.
o4 mini is a disappointment. Worse than Gemini 2.5 pro while costing 3 times more.
OpenAI still has big problems with cost. They released o1 back in Sept of 2024. It took them a long while to release o3 (they skipped o2 for copyright reasons). OpenAI has a slow release cadence in addition to being expensive, even if they are still competing for the performance crown. Deepseek is rumored to release R2 within weeks, so this is a big opportunity for them.
