OpenCode is an open-source AI coding assistant that runs in your terminal.

## Install

Install the [OpenCode CLI](https://opencode.ai):

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

<Note>OpenCode requires a larger context window. It is recommended to use a context window of at least 64k tokens. See [Context length](/context-length) for more information.</Note>

## Usage with Ollama

### Quick setup

```bash
ollama launch opencode
```

To configure without launching:

```shell
ollama launch opencode --config
```

<Note>`ollama launch opencode` passes its configuration to OpenCode inline via the `OPENCODE_CONFIG_CONTENT` environment variable. OpenCode deep-merges its config sources on startup, so anything you declare in `~/.config/opencode/opencode.json` is still respected and available inside OpenCode. Models declared only in `opencode.json` won't appear in `ollama launch`'s model-selection menu.</Note>
