Important**:** there is only one person working on NeuroAPI and all related projects at the moment. I don't have an established team, so I have to do everything on my own. Various problems can arise due to this, especially within the free usage.
{% endhint %}

## **About the project**

[**NeuroAPI**](https://neuroapi.host/) was created to offer free API access to ChatGPT-3.5, ChatGPT-4, and other language models (LLMs).

In addition to API access, we provide:

* PC client: [NeuroGPT](https://github.com/Em1tSan/NeuroGPT)
* Online chat: [NeuroAPI Chat](https://chat.neuroapi.host/)

To get started, you need to generate an API key. Follow the [Instructions for generating an API key](https://github.com/Em1tSan/NeuroGPT/wiki/Obtaining-an-API-Key) to create your key.
