# Models and Pricing

> Supported model IDs and endpoint pricing for LLMLayer.

## Supported Answer Models

| Model                | Pricing style               | Best for                     |
| -------------------- | --------------------------- | ---------------------------- |
| `llmlayer-web`       | Flat `$0.007 × max_queries` | Default web-grounded answers |
| `llmlayer-fast`      | Flat `$0.009 × max_queries` | Fast answers                 |
| `openai/gpt-4o-mini` | Token priced + LLMLayer fee | Budget token-priced answers  |
| `openai/gpt-5.1`     | Token priced + LLMLayer fee | Premium reasoning            |

<Note>
  The `openai/gpt-5.1` backend mapping is intentionally left for your later backend update.
</Note>

## Provider Keys

`provider_key` is accepted for backward compatibility but currently ignored; provider usage is not billed to the user's provider account.

Use LLMLayer response fields and the dashboard ledger as the billing source of truth.

## Answer Pricing

### LLMLayer flat-price models

```text theme={null}
llmlayer-web  = $0.007 × max_queries
llmlayer-fast = $0.009 × max_queries
```

### Token-priced models

```text theme={null}
total = ($0.004 × max_queries)
      + model input token cost
      + model output token cost
      + optional image search cost
```

Current token prices:

| Model                |               Input |               Output |
| -------------------- | ------------------: | -------------------: |

## Cost Control

* Start Answer requests with `llmlayer-web` and `max_queries=1`.
* Use Web Search + Scraper when you need to select sources before asking an LLM.
* Use Extract only for fields you actually need.
* Request one scrape format unless you need multiple outputs.
* Read `cost`, `llmlayer_cost`, and `model_cost` from responses when present.
