OpenCode | Ollama 日本語

OpenCode is an open-source coding agent that runs in your terminal, reads your project, edits files, and runs commands.

Ollama configures OpenCode to use local and cloud models.

Get started

Launch OpenCode with Ollama:

ollama launch opencode

Capabilities

Models

Choose a model with enough context for your repository.

Note

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

Manual setup

1. Install OpenCode

macOS / Linux

Windows

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.

See OpenCode's config precedence.
