How can I switch to the Claude Sonnet model in GitHub Copilot for IntelliJ?

Below is some guidance based on updates from our documentation regarding model names and usage:

IntelliJ Integration vs. VS Code

The VS Code extension provides a visual button for model selection, which is unique to that environment. As of now, there isn’t an equivalent built‑in feature in IntelliJ. In IntelliJ you’ll need to configure your chosen model manually—typically by specifying the API model name in your settings or configuration file when making API calls.

Using Claude Sonnet

If you’re looking to use a Claude Sonnet model, be sure to select the right variant for your needs. For example, if you want the one with the highest intelligence, you might choose the Claude 3.5 Sonnet version. According to our documentation, the API names for this model are:

• Upgraded version:
  claude-3-5-sonnet-20241022
• Previous version:
  claude-3-5-sonnet-20240620

Alternatively, if your work requires a balance of intelligence and speed, you might be considering Claude 3 Sonnet (claude-3-sonnet-20240229).

Workaround Steps

1. Identify Your Integration Method:
   Determine how your IntelliJ project interacts with Anthropic’s API (e.g., via a client library or direct REST calls).

2. Manually Configure the Model:
   Update your configuration or API call to specify the desired API model name. For instance, when setting up your API client, include the appropriate API model name (see examples below).

3. Verify and Test:
   After configuration, test your application to build confidence that the correct model is being used for your interactions.

Example Configuration

If you’re using a JSON-based configuration file for your API client, your file might include an entry like this:

JSONCopied
{
  "api_model": "claude-3-5-sonnet-20241022",
  "api_key": "YOUR_API_KEY_HERE",
  "other_config": "value"
}

If you’re configuring this in code, ensure that the request payload specifies the model accordingly. For example, in a Java REST client, you might see:

JAVACopied
JSONObject requestBody = new JSONObject();
requestBody.put("model", "claude-3-5-sonnet-20241022");
// set other parameters as needed

// then perform your API request using your client of choice

Next Steps

Because there isn’t a built-in IntelliJ interface like the VS Code button, you may consider writing a small helper or plugin to streamline switching models if this is a frequent need. Refer to our API and model documentation for detailed instructions on all supported model options.

This should give you a path forward when using Claude Sonnet in IntelliJ. If you need further assistance with API configuration or integration details, please refer to our documentation or reach out with more specific questions.
