OpenAI launched its latest o3 mini AI model last week as promised. The new model has improved reasoning abilities, especially in math and science.
O3-mini Release “advances the boundaries of what small models can achieve” Openai Saysand it appears to respond 24% faster than o1 mini model it is replacing. External testers have found that o3 mini answers are preferred to o1 mini answers 56% of time and contain 39% less mistakes.
Like o1 mini, this reasoning AI model shows its workings above the responses so you can check its ‘thought processes’ involved. This reasoning can be combined with web searches, but this integration is still in the early stages.
The release comes after a turbulent week in AI. China’s DeepSeek models, which were offered free, attracted millions of users because of their speed and accuracy. Now OpenAI is attempting to reclaim some of that limelight (and traffic).

OpenAI o3 mini is now available on ChatGPT, the API and for Pro users. Plus & Team users have tripled the rate limits compared to o1-mini. Clicking the reason in the text input field will allow users to download o3-mini for free until January 31, 2025. OpenAI has not specified the limits of its use, but they are likely to be similar to current restrictions on GPT-4o – a few queries per hour.
Paying users can select o3 mini from the model picker at the top left corner. If you have a Plus, Team, or Pro plan, you can access o3 Mini 150 times per day. The Pro plan gives you unlimited access for just $200 (about PS160 / AU$320).
ChatGPT users who pay also have access to the o3 mini-high model, which applies the same reasoning but takes longer to respond and think. If you don’t mind a few seconds of extra waiting, it can boost performance even more.
