Subscription limits

Hi again,
in my dashboard it is written:


You've used


requests out of your


monthly fast requests quota.

**You may use unlimited slow requests. These may run slower at times of peak demand.**


You've used


fast requests of this model. You have no monthly quota.

The part in bold what does it mean? There are such a thing as gpt4 slow requests If so can I choose when to use them not to consume my gtp4 credits?

Thank u in advance

I don’t think you can choose when to use fast requests for GPT4.
You have 500 fast requests and then you have “slow” requests.
