## Model Format

Models use the `provider/model-name` format:

anthropic/claude-sonnet-4-20250514
google/gemini-2.5-pro-preview-06-05
deepseek/deepseek-r1
```

## How It Works

<Steps>
  <Step title="Send a request">
    Make an OpenAI-compatible API call to `https://api.eachlabs.ai/v1` with your each::labs API key. That's it.
  </Step>

  <Step title="LLM Router does its thing">
    Validates your request, checks the cache, picks the best provider. All in milliseconds.
  </Step>

  <Step title="Get your response">
    Standard OpenAI-compatible response. Works with any SDK or framework that speaks OpenAI.
  </Step>
</Steps>

## Pricing

You only pay for the tokens you use. Pricing varies per model and we match the original provider's pricing, so you're never overpaying. Check per-model costs on the [Available Models](/llm-router/models) page or in your [dashboard](https://www.eachlabs.ai).
