## Quickstart

### Installing and running LLMX CLI

Install globally with npm:

```shell
npm install -g @valknarthing/llmx
```

Then simply run `llmx` to get started:

```shell
llmx
```

<details>
<summary>You can also go to the <a href="https://github.com/valknarthing/llmx/releases/latest">latest GitHub Release</a> and download the appropriate binary for your platform.</summary>

Each GitHub Release contains many executables, but in practice, you likely want one of these:

- macOS
  - Apple Silicon/arm64: `llmx-aarch64-apple-darwin.tar.gz`
  - x86_64 (older Mac hardware): `llmx-x86_64-apple-darwin.tar.gz`
- Linux
  - x86_64: `llmx-x86_64-unknown-linux-musl.tar.gz`
  - arm64: `llmx-aarch64-unknown-linux-musl.tar.gz`

Each archive contains a single entry with the platform baked into the name (e.g., `llmx-x86_64-unknown-linux-musl`), so you likely want to rename it to `llmx` after extracting it.

### Using LLMX with LiteLLM

LLMX is powered by [LiteLLM](https://docs.litellm.ai/), which provides access to 100+ LLM providers including OpenAI, Anthropic, Google, Azure, AWS Bedrock, and more.

**Quick Start with LiteLLM:**

```bash
# Set your LiteLLM server URL (default: http://localhost:4000/v1)
export LITELLM_BASE_URL="http://localhost:4000/v1"
export LITELLM_API_KEY="your-api-key"

# Run LLMX
llmx "hello world"
```

**Configuration:** See [LITELLM-SETUP.md](./LITELLM-SETUP.md) for detailed setup instructions.

You can also use LLMX with ChatGPT or OpenAI API keys. For authentication options, see the [authentication docs](./docs/authentication.md).

### Model Context Protocol (MCP)

LLMX can access MCP servers. To configure them, refer to the [config docs](./docs/config.md#mcp_servers).

### Configuration

LLMX CLI supports a rich set of configuration options, with preferences stored in `~/.llmx/config.toml`. For full configuration options, see [Configuration](./docs/config.md).
