# Available models and pricing

> Discover all available LLM models and their pricing through the ATXP LLM Gateway

The ATXP LLM Gateway provides access to models from multiple providers with transparent, pay-per-use pricing. You can discover all available models and their current pricing through the API.

## View available models

Query the `/models` endpoint to see all available models and their pricing:

```bash theme={null}
curl -X GET "https://llm.atxp.ai/v1/models" \
  -H "Authorization: Bearer $ATXP_CONNECTION_STRING"
```

<Info>
  When using a model in your API calls, use the model `id` without the company prefix. For example, to use the `gpt-4.1` model via the LLM Gateway, pass `gpt-4.1` as the model parameter, not the full ID of `openai/gpt-4.1` returned from the models endpoint.
</Info>

## Model categories

The LLM Gateway provides access to models across different categories:

* **GPT models**: OpenAI's latest models including GPT-4, GPT-3.5, and more
* **Claude models**: Anthropic's Claude models for advanced reasoning
* **Open source models**: Llama, Qwen, and other open-source alternatives
* **Specialized models**: Models optimized for specific tasks and use cases

## Pricing

All models use transparent, pay-per-use pricing based on tokens consumed. Pricing is automatically calculated and charged to your ATXP account balance. You can view current pricing for any model through the `/models` endpoint.
