opencode uses the AI SDK and Models.dev to support for 75+ LLM providers and it supports running local models.

Most popular providers are preloaded by default. If you've added the credentials for a provider through opencode auth login, they'll be available when you start opencode.

Learn more about providers.

Once you've configured your provider you can select the model you want by typing in:

/models

There are a lot of models out there, with new models coming out every week.

:::tip Consider using one of the models we recommend. :::

However, there are a only a few of them that are good at both generating code and tool calling.

Here are the ones we recommend with opencode:

• Claude Sonnet 4
• Claude Opus 4
• Kimi K2
• Qwen3 Coder
• GPT 4.1
• Gemini 2.5 Pro

To set one of these as the default model, you can set the model key in your opencode config.

{
  "$schema": "https://opencode.ai/config.json",
  "model": "lmstudio/google/gemma-3n-e4b"
}

Here the full ID is provider_id/model_id.

If you've configured a custom provider, the provider_id is key from the provider part of your config, and the model_id is the key from provider.models.

When opencode starts up, it checks for the following:

1. The model list in the opencode config.

   {
     "$schema": "https://opencode.ai/config.json",
     "model": "anthropic/claude-sonnet-4-20250514"
   }

   The format here is provider/model.

2. The last used model.

3. The first model using an internal priority.
