Yesterday, OpenAI released o3-mini and o3-mini-high and it’s available now in ChatGPT and the API.

o3-mini is fast at advanced reasoning, while o3-mini-high is great at coding and logic.

Here’s the amazing part: o3-mini-high’s coding average on LiveBench is 82.74. Other models don’t come even close: o1 (69.69) claude 3.5 sonnet (67.13), deepseek-r1 (66.74).

o3-mini-high is the best model for coding right now. Period.

What makes things better is that even free users can try o3-mini in ChatGPT (selecting the Reason button). Plus and Team users have a limit of 150 messages per day with o3-mini, while Pro users have unlimited access to o3-mini and o3-mini-high.

Let’s explore how you can use o3-mini for coding and take a closer look at how well it performs compared to other models

I just used o3-mini and o3-mini high for my engineering proposal. Compared to ds r1 they suck. Not good at all

Open AI generated angular 17 instead of angular 19 style template code. I guess the models struggle when a new release of a language introduces new features or concepts.
