## Quickstart

### Installing and running VT Code

Install globally with Cargo:

```shell
cargo install vtcode
```

Alternatively, with Homebrew:

```shell
brew install vinhnx/tap/vtcode
```

Then simply run `vtcode` to get started:

```shell
vtcode
```

<details>
<summary>You can also download pre-built binaries from <a href="https://github.com/vinhnx/vtcode/releases/latest">GitHub Releases</a>.</summary>

Available for:

-   **macOS**: Apple Silicon (`aarch64-apple-darwin`) and Intel (`x86_64-apple-darwin`)
-   **Linux**: x86_64 and ARM64 architectures
-   **Windows**: x86_64 architecture

Each archive contains the executable - extract and rename to `vtcode` if needed.

</details>

### Configuration

Set your API key for your preferred provider:

```shell
export OPENAI_API_KEY="your_key_here"
# or
export ANTHROPIC_API_KEY="your_key_here"
# or
export XAI_API_KEY="your_key_here"
# or
export GEMINI_API_KEY="your_key_here"
# or
export OPENROUTER_API_KEY="your_key_here"
```

Alternatively, create a `.env` file in your project directory:

```shell
# .env file
OPENAI_API_KEY=your_openai_key_here
ANTHROPIC_API_KEY=your_anthropic_key_here
XAI_API_KEY=your_anthropic_key_here
GEMINI_API_KEY=your_gemini_key_here
OPENROUTER_API_KEY=your_openrouter_key_here
```

**Automatic API Key Inference**: VTCode automatically uses the correct environment variable based on your provider setting in `vtcode.toml`:

-   `provider = "openai"``OPENAI_API_KEY`
-   `provider = "anthropic"``ANTHROPIC_API_KEY`
-   `provider = "gemini"``GEMINI_API_KEY`
-   `provider = "xai"``XAI_API_KEY`
-   `provider = "deepseek"``DEEPSEEK_API_KEY`
-   `provider = "openrouter"``OPENROUTER_API_KEY`

VT Code supports advanced configuration via `vtcode.toml`. See [Configuration](docs/project/) for details.

### Using OpenRouter models

OpenRouter support unlocks any hosted model by ID, including the latest Grok and Qwen3 coding releases.

```shell
vtcode --provider openrouter --model x-ai/grok-code-fast-1 chat
```

Or persist the configuration in `vtcode.toml`:

```toml
[agent]
provider = "openrouter"
default_model = "qwen/qwen3-coder"
```

Custom model IDs are accepted as long as they match your OpenRouter account access. Streaming and tool-calling work out of the box
using the OpenAI-compatible Responses API.
