Models

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

Providers

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.

Recommended 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

Set a default

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

opencode.json

{
  "$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.

Loading models

When opencode starts up, it checks for the following:

1. The model list in the opencode config.

   opencode.json

   {
     "$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.
