Models

Choose a model with enough context for your repository.

<CardGroup cols={2}> <Card title="Cloud models" icon="cloud" href="https://ollama.com/search?c=cloud"> Use larger models without downloading them. </Card> <Card title="Local models" icon="hard-drive" href="https://ollama.com/search?c=tools"> Choose a model and set a 64k+ context window. </Card> </CardGroup>

<Note>OpenCode requires a context length of 64k or higher. See Context length for more information.</Note>

Manual setup

<p className="manual-step-title">1. Install OpenCode</p> <CodeGroup>

shell

curl -fsSL https://opencode.ai/install | bash

powershell

npm install -g opencode-ai

</CodeGroup> <p className="manual-step-title">2. Configure Ollama as a provider</p>

Add an Ollama provider to opencode.json:

json

{
  "$schema": "https://opencode.ai/config.json",
  "provider": {
    "ollama": {
      "npm": "@ai-sdk/openai-compatible",
      "name": "Ollama",
      "options": {
        "baseURL": "http://localhost:11434/v1"
      },
      "models": {
        "qwen3.5": {
          "name": "qwen3.5"
        }
      }
    }
  }
}

<p className="manual-step-title">3. Run OpenCode</p>

shell

opencode

To configure OpenCode with Ollama without starting an interactive session:

shell

ollama launch opencode --config

Configuration precedence

ollama launch opencode starts OpenCode with an inline config for the selected Ollama model. It does not overwrite ~/.config/opencode/opencode.json; existing OpenCode settings still apply.

Models defined only in opencode.json do not appear in the ollama launch model picker.

See OpenCode's config precedence.
