Cursor on Layer X1.

Cursor's models settings accept an OpenAI-compatible override — point the OpenAI base URL at the gateway, paste your key, and add lx1 model names.

Configure

In Cursor Settings → Models:

Enable Override OpenAI Base URL and set it to:

https://api.layerx1.in/v1

Paste your lx1_ key into the OpenAI API Key field.
Under model names, add a custom model for each catalog id you want to use — e.g. lx1-gpt-oss-120b, lx1-glm-5, lx1-sonnet-4.6.
Click Verify — Cursor sends a probe to /v1/chat/completions and should turn green.

Troubleshooting

Verify fails? The base URL must end in /v1 and at least one custom model name must be a valid catalog id — Cursor verifies with the model currently selected.
Model "not found"? Model names are exact — lx1-glm-5, not glm-5. Copy ids from the catalog page.
Built-in models stopped working?Expected: overriding the OpenAI base URL points Cursor's OpenAI slot at Layer X1. Toggle the override off to switch back.

Note

Cursor uses its own accounts for some built-in features; the override governs the chat/composer models you add by name. Every lx1 model you add is included in your plan — pick per task, not per budget.
