## FAQ

### Where do these prices come from?

From the open-source LiteLLM price list, refreshed every 4 hours and, for providers with an automatic check, compared field by field with the provider's official pricing page. Each model page shows what was verified.

### Why is a model missing?

We list first-party chat and reasoning models with published per-token prices. Audio, image, realtime, fine-tuned and third-party-hosted models are out of scope; deprecated models move to the retired list. Missing or wrong entries can be reported on the feedback board.
