Hi @burnt dawn. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:
The usage limits for GPT-4o depend on the type of user you are.
If you are a Free tier user, you can use GPT-4o only a limited number of times within a three-hour window. Once you've reached the limit, you'll be notified and invited to continue your conversation using GPT-3.5 or to upgrade to ChatGPT Plus. When you hit your limit for GPT-4o, you won't be able to use GPTs until your rate limit resets. The exact number of messages/prompts you can generate within a fixed amount of time is not specified, but it's noted that it can be adjusted dynamically based on load[^1^][^2^].
If you are a ChatGPT Plus user, as of May 13th 2024, you will be able to send up to 80 messages every 3 hours on GPT-4o[^3^][^4^]. Please note that unused messages do not accumulate (i.e., if you wait 6 hours, you will not have 80 messages available to use for the next 3 hours on GPT-4o)[^3^][^4^].
In addition to these limits, there are also separate usage rate limits for certain tools, including data analysis with ChatGPT, file and image uploads, and browsing with ChatGPT[^2^].
If you're hitting your usage limit frequently, you might want to consider upgrading your usage tier to increase your rate limits[^5^].
