# Cursor

[Cursor](https://cursor.com) is an AI IDE. Through its bring-your-own-key (BYOK) settings, you can configure an OpenAI API key and a Base URL override so Cursor chat can run on ScitiX models.

Two product boundaries from Cursor's own docs are important:

* Custom API keys only work with chat models. Tab completion and other features built on Cursor's own models continue using Cursor's built-in models.
* BYOK requests are sent through Cursor's backend to the configured endpoint, and Cursor's Zero Data Retention policy does not apply to BYOK usage.

## Configure

Create an API Key on the [API Keys](https://console.scitix.ai/model-inference/api_keys) page, then open **Cursor Settings → Models**.

1. In the model list, uncheck the pre-configured models.

   Pre-configured models route through Cursor's own channels, not your key.

2. Click **Add Custom Model** and add `DeepSeek-V4-Flash`.

   Do not add `glm-5.2` here. Cursor's built-in catalog already contains a *GLM 5.2* entry, so the duplicate name is rejected. The built-in entry uses Cursor's official channel, not your key. Pick ScitiX model IDs that do not collide with [Cursor's built-in list](https://cursor.com/docs/models), such as `DeepSeek-V4-Pro` or `DeepSeek-V4-Flash`.

3. Scroll to **API Keys → OpenAI API Key** and paste your ScitiX API Key.

4. Enable **Override OpenAI Base URL** and set it to:

   ```text theme={null}
   https://api.scitix.ai/model-api/v1
   ```

5. Turn the **OpenAI API Key** toggle on.

<Info>
  The Base URL override is no longer described in Cursor's official documentation, and its UI location may change between versions. As of late July 2026, it lives under **Cursor Settings → Models → API Keys**.

## Verify

Open Chat (`Cmd/Ctrl+L`), select the model you added in the picker, and send a message. A normal reply confirms that the connection works.

Since these model IDs only exist on ScitiX, a reply is proof that the override is in effect. You can also see the calls on the ScitiX console's usage page.

## FAQ

* **Selecting a built-in model gets no reply** when only your BYOK key is configured. Built-in entries, such as the catalog's GLM 5.2, do not route through the Base URL override. Use the models you added through **Add Custom Model**.
* Tab completion not working on ScitiX models is expected. It is a product limitation of custom keys, not a configuration error.
