It's interesting you say that because o3, while being a considerable improvement over OpenAI's other models, still doesn't match the performance of Opus 4 and Gemini 2.5 Pro by a long shot for me. However, o3 resides in the ChatGPT app, which is still superior to the other chat apps in many ways, particularly the internet search implementation works very well.
What languages do you use it with and IDE? I use it in Cursor mainly with Max reasoning on. I spent around $300 on token based usage for o3 alone in May still only accepting around 33% of suggestions though. I made a post on X about this the other day but I expect that amount of rejections will go down significantly by the end of this year at the rate things are going.
I think my coding model ranking is something like Claude Code > Claude 4 raw > Gemini > big gap > o4-mini > o3
