Manual setup

1. Install OpenCode

```shell macOS / Linux curl -fsSL https://opencode.ai/install | bash ```

npm install -g opencode-ai

2. Configure Ollama as a provider

Add an Ollama provider to opencode.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"
        }
      }
    }
  }
}

3. Run OpenCode

opencode

To configure OpenCode with Ollama without starting an interactive session:

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.
