LLMs available free through a gateway

378 models are served at zero cost by at least one tracked gateway. Free here means a gateway publishes a price of zero — not that it is unmetered, unlimited, or free forever.

Showing the top 50 of 378. Search the full catalog to go further.

How this is measured. Includes any model where at least one tracked gateway publishes an input price of exactly zero, or flags the model as free. It says nothing about rate limits, daily caps, or how long the offer lasts — those are the gateway's terms, not something a catalog publishes. A model with no published price is not counted as free.
