Cursor

Use LLMRPM as a custom OpenAI-compatible model in Cursor.

Configuration

Setting	Value
API shape	OpenAI-compatible
Base URL	`https://llmrpm.com/api/v1`
Auth	`Authorization: Bearer llmrpm_...`

Open the Cursor command palette and choose Open User Settings (JSON).
Add cursor.general.openAIBaseURL with https://llmrpm.com/api/v1.
Add cursor.general.openAIAPIKey with your LLMRPM API key.
Alternatively use Settings → Models, fill Base URL, API Key, and a public model ID.

Example

settings.json

{
  "cursor.general.openAIBaseURL": "https://llmrpm.com/api/v1",
  "cursor.general.openAIAPIKey": "llmrpm_YOUR_KEY"
}

Cursor UI

Open Cursor Settings
Models > Add custom model
Provider: OpenAI Compatible
Base URL: https://llmrpm.com/api/v1
API Key: llmrpm_YOUR_KEY
Model: claude-sonnet-5

Recommended models

Any public ID from the model list works. Common picks:

claude-sonnet-5— strong model for reasoning, refactors, and coding agents.
claude-haiku-4.5— fast option for autocomplete, small questions, and lightweight tasks.
deepseek-v4-pro— alternative based on your active catalog and plan.

Troubleshooting

Symptom	Cause & fix
Authentication error	Check that the API key has no extra spaces and has not been revoked in the dashboard.
Model rejected	Use a public model ID returned by GET /api/v1/models; do not use display names or aliases.
Connection issue	Confirm the configured base URL is exactly the one shown above and that your network allows HTTPS to llmrpm.com.

Notes

Prefer a strong model for chat and a faster one for lightweight edits.
Cursor may require toggling off other built-in providers to route through the custom base URL.
