Limitations on the OpenAI o-series reasoning models on ChatGPT

https://help.openai.com/en/articles/9824962-openai-o3-o4-mini-and-o3-mini-usage-limits-on-chatgpt-and-the-api

If you have a ChatGPT Plus, Pro, Team, or Enterprise account, you can select o3 or o4-mini in the model selector at the top of the page, but it is rolling out.

With a ChatGPT Plus, Team or Enterprise account, you have access to

50 messages a week with OpenAI
150 messages a day with OpenAI o4-mini
50 messages a day with o4-mini-high

The ChatGPT Pro plan offers near unlimited access to our o3, o4-mini, and 4o models. However, usage must adhere to Terms of Use, which prohibits, among other things.

ChatGPT Plus, Pro, and Team users will see o3, o4-mini, and o4-mini-high in the model selector starting today, REPLACING o1, o3-mini, and o3-mini-high.

ChatGPT Enterprise and Edu users will gain access in one week.
Rate limits across all plans remain unchanged from the prior set of models.

We expect to release o3-pro in a few weeks with full tool support. For now, Pro users can still access o1-pro in the model picker under ‘more models.’

I think there is a mistake:

The page FAQ needs a correction:

What is the word “OpenAI” here, is it o3 on FAQ?

50 messages a week with OpenAI

The post on X is saying “Rate limits across all plans remain unchanged from the prior set of models.

If o1 replace to o3, probably it should be “50 messages a week with o3”.

Also second word “OpenAI” is not necessary in content like “with OpenAI o4-mini”. “with o4-mini” is OK.

Hi, welcome to the community!

Thanks for your sharing, but there are no longer o1, o3-mini, and o3-mini-high models on ChatGPT anymore. Also , 2025 April 30 is the last day for GPT-4.

Model selector starting today, REPLACING:

New Model Old Model
o3 o1
o4-mini o3-mini
o4-mini-high o3-mini-high

I don’t know why they remove the o1 model from ChatGPT plus the o3 model is not good as the model o1 model I subscribe ChatGPT plus because of the o1 model now it’s remove from the ChatGPT plus
