# Introducing Friendli Model APIs

> Get started with Friendli Model APIs to access popular AI models via API. No infrastructure setup or GPU management required.

Friendli Model APIs let you access frontier open-source models through a ready-to-use API endpoint—no deployment required, and you pay only for what you use.

## What Are Friendli Model APIs

Friendli Model APIs provide instant access to a curated set of models, powered by [Friendli Engine](https://friendli.ai/why-friendliai) for high-performance, cost-efficient inference. With Friendli Model APIs, you can:

* **Access popular models instantly**: Use state-of-the-art models without downloading, hosting, or optimizing them yourself.
* **Integrate in a few lines of code**: Connect through the [Friendli Python SDK](/sdk/python-sdk) or any OpenAI-compatible client.
* **Pay per token, not per GPU**: You are billed only for what you use, with no idle GPU cost. See [Pricing](/guides/model-apis/pricing) for details.
