Model list
Official model names, the models listed now and how to see which ones your key can use.
Relayvia takes official model names, so there are no aliases to learn. This page lists the models available now.
Official names
Set model to the name the model's maker uses, for example claude-opus-5, gpt-5.5 or gemini-3.6-flash. Responses show the same name you sent.
Models available now
Prices, context length and capabilities of each model are in the model catalog and on the pricing page.
The model list could not be loaded. See the model catalog for every listed model.
Models your key can use
A key belongs to a group and can be limited to some models. GET /v1/models returns exactly the models that key can call. A model that is not listed returns 404 model_not_found; a listed model the key may not use returns 403 forbidden.
