Free AI APIs & Sites

This repository is a showcase of AI APIs and Websites that offer free usage of AI models under g4f principles.

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

I, @zukixa, am the queen of zukijourney, but I am also the only one to actively maintain this list. We are not endorsing any of the listed services! Some of them might be considered controversial. We are not responsible for any legal, technical or any other damage caused by using the listed services. Data is provided without warranty of any kind. Use these at your own risk!

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.}

Tier 3 — 'Inconsistent' APIs

Tier 5 -- Caution Advised! Questionable AI API Offerings

Service	# of Users1	NSFW/RP Ok?	Open Source?	Owner(s)	Models	Why Potentially Misleading?
AnyAI	1,817	✅ Allowed	❌	Meow18838	Models	Most influential person in the server is a terrible being.
CablyAI	1,240	✅ Allowed	❌	CablyAI	Models	Most influential person in the server is a terrible being.
ShadowJourney	680	❌ Forbidden	❌	ichatei	Models	Admitted privately to DDOS competition. Very weird owner. Stability is often questioned due to supposed fake models. Use at your own risk.

Non-Tiered -- Non-API AI Servers:

Service	# of Users1	What does it provide?	Other Notes
g4f.ai	12,837	The OG server. Hub of the github repository that started it all.	Inactive

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.
