# Cursor

> Use ShuYou models in Cursor IDE via OpenAI or Anthropic-compatible settings.

# Cursor

Use **ShuYou** as the model backend in [Cursor](https://cursor.com/) for AI-assisted coding in the editor.

ShuYou supports both OpenAI-compatible and Anthropic-compatible protocols. Cursor settings vary by version; use the path that matches your Cursor build.

## Prerequisites

1. Install [Cursor](https://cursor.com/download).
2. Create a ShuYou API key in the [console](https://shuyou.ai/signin).

## Option A: OpenAI-compatible (Chat Completions / Responses)

Best for GPT and other models exposed via ShuYou's OpenAI protocol.

1. Open **Cursor Settings → Models**.
2. Enable **Override OpenAI Base URL** (or equivalent custom endpoint option).
3. Set:
   * **Base URL:** `https://api.shuyou.ai/v1`
   * **API Key:** your ShuYou API key
4. Add or select a model slug from the [ShuYou model catalog](https://shuyou.ai/models), for example `openai/gpt-4o`.

## Option B: Anthropic-compatible (Claude models)

Best for Claude-family models on ShuYou.

1. Open **Cursor Settings → Models**.
2. Configure the Anthropic / Claude provider override if available:
   * **Base URL:** `https://api.shuyou.ai`
   * **API Key:** your ShuYou API key
3. Choose a model slug that supports **Anthropic API Compatible** on ShuYou, for example `anthropic/claude-sonnet-4.5`.

Reference: [Create Messages](/en/api-reference/language-series/anthropic/create-messages).

## Verify

1. Open a project in Cursor.
2. Start an inline chat or Agent session with your configured model.
3. Confirm responses return without `401` / `403` errors.

## FAQ

**Model not found:** Use the exact slug from [shuyou.ai/models](https://shuyou.ai/models), including provider prefix when required.

**401 / 403:** Verify the API key, billing balance, and that the model is available on your plan.

**Wrong protocol:** OpenAI slugs need base URL `https://api.shuyou.ai/v1`; Anthropic slugs need `https://api.shuyou.ai`.

<Tip>
  Cursor UI labels change between releases. If you cannot find override fields, check Cursor's latest docs for "custom API" or "bring your own key" settings.
