Cursor lets you bring your own OpenAI-compatible endpoint. Point it at GMI Cloud and any model in the GMI catalog becomes available inside Cursor, chat, inline edits, and Composer all work.

​
Prerequisites

  • Cursor Pro: the “Override OpenAI Base URL” setting is gated behind the Pro plan. Free-plan accounts can’t follow this guide.
  • A GMI Cloud account at console.gmicloud.ai
  • Cursor installed
  • About 5 minutes

​
Step 1. Get your GMI API key

  1. Sign in to console.gmicloud.ai.
  2. Open API Keys → Create API Key.
  3. Copy the key now, it won’t be shown again.

​
Step 2. Open Cursor’s model settings

In Cursor, open Settings → Models (or ⌘ , then search “Models”).

​
Step 3. Add the GMI base URL

Scroll to API Keys.
  1. Enable OpenAI API Key and paste your GMI API key into the field (Cursor uses the OpenAI key slot for any OpenAI-compatible provider).
  2. Enable Override OpenAI Base URL.
  3. Set the URL to: 
    https://api.gmi-serving.com/v1
That’s the only base-URL change you need.

​
Step 4. Add the models you want

In the Models list at the top of the settings page:
  1. Click Add or search model.
  2. Type the GMI model ID (e.g. anthropic/claude-opus-4.7, zai-org/GLM-5.1-FP8, moonshotai/Kimi-K2.6, deepseek-ai/DeepSeek-V4-Pro).
  3. Toggle the new model on.
Repeat for each model you want to expose. Cursor will route requests to GMI under these names. Browse model IDs in the Text models catalog.

​
Step 5. Use it

Open any chat or Composer panel and select one of your GMI-routed models from the dropdown. Inline edits and ⌘ K work too.

​
Tips

  • Mixing providers. You can keep Cursor’s built-in models on (Composer 2.5, Sonnet 4.6, etc.) and add GMI models alongside them. Cursor only uses the GMI base URL for models you added manually.
  • Bad model name. If a request 404s, the model ID is wrong. GMI model IDs always include the provider prefix (e.g. openai/gpt-5.5, not gpt-5.5).
  • Pro required. The OpenAI API Key field alone doesn’t change routing, both toggles (key + base URL override) must be on.
