Since Cursor is a fork of VS Code, you can install the Qwen Code Companion extension directly from the Marketplace, but for the most powerful experience (using the latest Qwen 2.5/3 Coder models), you should configure them as a custom model within Cursor’s core settings.
Option 1: Native Extension (Easiest)
This adds the specific Qwen sidebar and features to Cursor.
Open Cursor and go to the Extensions view (Ctrl+Shift+X or Cmd+Shift+X).
Search for “Qwen Code Companion” (published by QwenLM).
Click Install.
Open the Qwen panel from the editor title bar icon or via the Command Palette (Cmd+Shift+P → Qwen Code: Open).
I cannot get openrouter to work with qwen3. if anyone can help, let me know. thanks!
Hey, OpenRouter isn’t officially supported by Cursor, so compatibility issues with models like Qwen3 are expected.
Supported BYOK (Bring Your Own Key) providers are OpenAI, Anthropic, Google, Azure OpenAI, and AWS Bedrock. You can set them up in Cursor Settings > Models. More details here: API keys documentation
Qwen isn’t available through any of these supported providers, so right now there’s no reliable way to use it via Cursor’s built-in AI features.
As for the Qwen Code Companion extension, it’s a third-party VS Code extension and works independently from Cursor’s AI features. We can’t support its setup, but you can try contacting the extension developers (QwenLM) if you run into issues.
