Cursor

Use ShuYou as the model backend in Cursor 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.
2. Create a ShuYou API key in the console.

​

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, for example openai/gpt-4o.

Reference: Create Chat Completion.

​

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.

3. Confirm responses return without 401 / 403 errors.

FAQ

Model not found: Use the exact slug from 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.
