# Firmware

Firmware provides a unified AI subscription that gives you access to models from Anthropic, OpenAI, Google, xAI, and DeepSeek via a single API key and OpenAI-compatible endpoint. One subscription enables all supported models.

## Setup

**Best for:** unified access to multiple model providers with one subscription.

Get your API key from https://app.firmware.ai

### CLI setup

```bash
moltbot onboard --auth-choice firmware-api-key
# or non-interactive
moltbot onboard --firmware-api-key "$FIRMWARE_API_KEY"
```

### Config snippet

```json5
{
  env: { FIRMWARE_API_KEY: "fw-..." },
  agents: { defaults: { model: { primary: "firmware/gpt-5.2" } } }
}
```
