OpenAI appears to have increased the rate limits for its recent o1 models, including o1 mini. Users can now send up to 50 messages per day on both models, whereas previously this was a weekly limit. Additionally, there are user reports suggesting that o1 mini is appearing in their drop-down menus, indicating that this model may soon become available to free users.

> We appreciate your excitement for OpenAI o1 and we want you to be able to use it more.  
>  
> For Plus and Team users, we have increased rate limits for o1-mini by 7x, from 50 messages per week to 50 messages per day.  
>  
> o1-preview is more expensive to serve, so we’ve increased the rate…

In case you missed it, o1 features advanced reasoning capabilities and is currently the [latest OpenAI model available on the market](https://www.testingcatalog.com/openai-released-o1-series-ai-models-with-enhanced-reasoning/).

Furthermore, it seems that the knowledge cutoff date for 4o has been updated to September 2024\. This update has occasionally appeared to users and has been confirmed by OpenAI employees, highlighting that this updated model was already available for testing on the Lmsys Arena.

> Excited to share that our September GPT-4o release is at #1 on lmsys arena!  
>  
> We quietly shipped an update to 4o in the dynamic API and in ChatGPT earlier this month. It's a big improvement for writing, coding, and multi-turn conversations, hope you try it out! [pic.twitter.com/z0ub2yaPTA](https://t.co/z0ub2yaPTA?ref=testingcatalog.com)

Lastly, [Perplexity](https://x.com/i/bookmarks/all?post%5Fid=1835874778768625683&ref=testingcatalog.com) has also integrated o1 in beta mode with very strict rate limits of 10 messages per day. It appears as a new separate focus mode but currently doesn't support search capabilities.
