# Using VS Code Language Model API With Roo Code
|
|
|
|
Roo Code includes *experimental* support for the [VS Code Language Model API](https://code.visualstudio.com/api/language-extensions/language-model-access). This API allows extensions to provide access to language models directly within VS Code. This means you can potentially use models from:
|
|
|
|
* **GitHub Copilot:** If you have a Copilot subscription and the extension installed.
|
|
* **Other VS Code Extensions:** Any extension that implements the Language Model API.
|
|
|
|
**Important:** This integration is highly experimental and may not work as expected. It is dependent on other extensions correctly implementing the VS Code Language Model API.
|
|
|
|
## Prerequisites
|
|
|
|
* **VS Code:** The Language Model API is available through VS Code (and is not currently supported by Cursor).
|
|
* **A Language Model Provider Extension:** You need an extension that provides a language model. Examples include:
|
|
* **GitHub Copilot:** If you have a Copilot subscription, the GitHub Copilot and GitHub Copilot Chat extensions can provide models.
|
|
* **Other Extensions:** Search the VS Code Marketplace for extensions that mention "Language Model API" or "lm". There may be other experimental extensions available.
|
|
|
|
## Configuration
|
|
|
|
1. **Open Roo Code Settings:** Click the gear icon (<Codicon name="gear" />) in the Roo Code panel.
|
|
2. **Select Provider:** Choose "VS Code LM API" from the "API Provider" dropdown.
|
|
3. **Select Model:** The "Language Model" dropdown will (eventually) list available models. The format is `vendor/family`. For example, if you have Copilot, you might see options like:
|
|
* `copilot - claude-3.5-sonnet`
|
|
* `copilot - o3-mini`
|
|
* `copilot - o1-ga`
|
|
* `copilot - gemini-2.0-flash`
|
|
|
|
## Limitations
|
|
|
|
* **Experimental API:** The VS Code Language Model API is still under development. Expect changes and potential instability.
|
|
* **Extension Dependent:** This feature relies entirely on other extensions providing models. Roo Code cannot directly control which models are available.
|
|
* **Limited Functionality:** The VS Code Language Model API may not support all the features of other API providers (e.g., image input, streaming, detailed usage information).
|
|
* **No Direct Cost Control:** You are subject to the pricing and terms of the extension providing the model. Roo Code cannot directly track or limit costs.
|
|
* **GitHub Copilot Rate Limits:** When using the VS Code LM API with GitHub Copilot, be aware that GitHub may impose rate limits on Copilot usage. These limits are controlled by GitHub, not Roo Code.
|
|
|
|
|
|
## Troubleshooting
|
|
|
|
* **No Models Appear:**
|
|
* Ensure you have VS Code installed.
|
|
* Ensure you have a language model provider extension installed and enabled (e.g., GitHub Copilot, GitHub Copilot Chat).
|
|
* If using Copilot, make sure that you have sent a Copilot Chat message using the model you would like to use.
|
|
* **Unexpected Behavior:** If you encounter unexpected behavior, it's likely an issue with the underlying Language Model API or the provider extension. Consider reporting the issue to the provider extension's developers.
