# Models

> Browse the model catalog, and tell confidential models from standard ones.

The platform serves a large catalog through a single endpoint, from open-weight models to proprietary
ones like GPT and Claude.

## Model ids

Each model has a `provider/model` id, such as `openai/gpt-5` or `qwen/qwen3-30b-a3b-instruct-2507`.
Pass it as the `model` field in a request. The same model may be offered under more than one id.

## Confidential and standard models

Some models run **confidentially**: inside a TEE, on a provider whose enclave the gateway verifies
before forwarding your prompt. Others are **standard** models from a third-party provider that is not
attested. Both are served through the attested gateway, but only a confidential model extends that
protection to the model itself.

A model's `is_tee` flag marks which kind it is, and the [receipt](/confidential-ai/receipts) proves
how a given response was served. See [Confidential models](/confidential-ai/confidential-models).

To confine an application to confidential models only, call the
[TEE-only endpoint](/guides/tee-endpoint) at `https://tee.redpill.ai` instead of the default base
URL.

## Choosing a model

Models differ in context length, accepted inputs, price, and supported parameters. The
[`GET /v1/models`](/api-reference/models) response carries these details for each model, so you can
match a model to what your application needs before you call.
