What "per model" and "per IP address" mean
- Per model: the cap applies to each model separately. On Groq, 1,000 requests a day to one model and 1,000 to another are both allowed.
- Per IP address: with no key, the service counts requests from your internet address. Everyone on one network, such as an office or a school, shares it.
- Per project: Gemini counts per Google Cloud project, not per key, so extra keys in the same project share one cap.
Combining free tiers
Using several free tiers together raises the total. The open-source OmniRoute gateway puts several free keys behind one address on your own computer and moves to the next one when a cap is reached. Each service's own terms still apply.
Running a model on your own computer
A model running on your own computer has no request cap; the limit is the computer's speed and memory. Run open models on your own computer covers the tools.
Words to know
- Rate limit: the most requests a service accepts in a minute, hour or day.
- Token: a piece of a word; the unit models read and write. See tokens and context windows.
- API key: the password an app uses to call a model. See what is an API key.
