# Supported Text Models

> Text model list supporting both Chat Completions and Responses API formats

> [!NOTE]
>
> **Note for users in mainland China:** Please use `https://toapis.cn` as the API endpoint (Base URL). Replace `https://toapis.com` with `https://toapis.cn` in the examples in this document.

The platform provides two API formats. Use the `model` parameter to switch models:

| API Format | Endpoint | Description |
| - | - | - |
| **Chat Completions** (default) | `POST /v1/chat/completions` | Classic chat API, compatible with OpenAI SDKs. [View docs](https://docs.toapis.com/docs/en/api-reference/chat/chat.md) |
| **Responses** (new) | `POST /v1/responses` | Newer OpenAI agentic API with function calling, built-in tools, and server-side multi-turn context. [View docs](https://docs.toapis.com/docs/en/api-reference/chat/responses.md) |

> [!TIP]
>
> Models marked as `Responses Only` only support the Responses API and do not support Chat Completions. Other models are called through Chat Completions by default.
