When using Superface with your GPT you may encounter an error similar to this:

The GPT usage cap for GPT-4 error

GPT-4 is currently limited to ~40 messages in a 3 hour window. Unfortunately, this limit is set by OpenAI and is not something that Superface can control.

Your usage limit will typically reset after 2 hours, after which you will be able to continue using your GPT.


This limitation is specific to custom GPTs where the model is already decided. In standard ChatGPT chats, the model will switch to GPT-3.5 if the GPT-4 limit is reached.
