# 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](https://relayvia.dev/models) and on the [pricing](https://relayvia.dev/pricing) page.

The model list could not be loaded. See the [model catalog](https://relayvia.dev/models) 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](https://relayvia.dev/docs/api/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`.
