Free AI APIs & Sites

This repository is a showcase of AI APIs and Websites that offer free usage of some/many AI models.

A better overview is now available on our website! Check it out here https://cas.zukijourney.com

To be added, your API must be of clean record, >100 members, stable, and support at least all chat & image generation functionalities in the OpenAI format, as displayed here

Overview of APIs

^{*: This list solely covers all providers I (@zukixa) was able to collect metrics in. Any mistakes are not my responsibility, as I am either banned, or not aware of x API.}

Note

A lot of the services also support specific models or higher usage rates for donators (such as us, zukijourney!), but we are just including the free tier here. Some of these services give you rewards over time etc., but I'm assuming here that you only have ~10 mins of time.

*1: CablyAI only provides this service either in limited, occasional free trials or after having you invite 10 more members.
