Openai Makes O3 Mini Free For All Chatgpt Users Plus Users Get O3 Mini High

Earlier, OpenAI was serving the much smaller “GPT-4o mini” to free ChatGPT users, with some GPT-4o usage as well. Now, all ChatGPT users can access the ‘o3-mini’ model which was announced in December, last year. The o3 series models were hailed as a breakthrough because o3 at the highest compute setting, cracked the hallowed ARC-AGI benchmark.
Talking specifically about the ‘o3-mini’ model which will be available to free users, its reasoning effort is set to “medium”. In AIME 2024 (a competitive math benchmark), o3-mini nearly matches the performance of the much larger o1 model.
In Codeforces (a competitive coding benchmark), o3-mini again performs better than o1. In terms of latency too, o3-mini is almost on par with GPT-4o. OpenAI says the o3-mini model delivers exceptional performance in science, math, coding, and reasoning problems.
As for ChatGPT Plus users, OpenAI has released the ‘o3-mini-high’ model which is even more powerful and the most capable AI model out there for coding. o3-mini-high scores much better than o1 in math and coding benchmarks including AIME 2024, Codeforces, and SWE-bench Verified. Only in GPQA Diamond (PhD-level Science Questions), o1 performs better than o3-mini-high. Both o3-mini and o3-mini-high models are rolling out to free and paid ChatGPT users, starting today. Of course, there is a rate limit for free users, but OpenAI has not disclosed it. However, OpenAI has tripled the rate limit for ChatGPT Plus users.
If you are a paid subscriber, the rate limit has been increased to 150 messages per day with o3-mini. Note that ChatGPT Pro users who are subscribed to the $200-per-month plan will have unlimited access to both o3-mini and o3-mini-high models.
All in all, for the first time, free ChatGPT users will have access to a far superior model, thanks to DeepSeek’s entry into the AI race. To use the o3-mini model, just select the “Reason” button in ChatGPT and start asking your questions.
