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.}

^{1: Last Updated 9/30/24}

Tier 1 -- Established, Premium-Service AI API Leaders:

Service	# of Users1	NSFW/RP Ok?	Open Source?	Owner(s)	Models	Other Notes
zukijourney	5511	Use /unf/chat... not /v1/	✅, Here	Our Team	Models	Largest & Oldest GPT-4 API still continuously around. Offers other popular AI-related Bots too.
HentAI	1125	All models with free_nsfw_access set to true. Dono-only otherwise	✅, Here	ThatLukinhasGuy	Models	Stable alternative API made by one of the Zukijourney devs.
NagaAI	3236	Forbidden	❌	ZentixUA	Models	Honorary successor to ChimeraGPT, the largest API in history (15k users).
FresedGPT	733	Forbidden	❌	Fresed	Models	Small API maintained by a surprisingly commited dev. Good quality.

Tier 2 -- Standard, Basic AI API Services:

Service	# of Users1	NSFW/RP Ok?	Open Source?	Owner(s)	Models	Other Notes
Oxygen	1139	Donator-Only	❌	TornadoSoftware	Models	Current Frontpage UI is stolen from Here, Dashboard UI from Here. Service stable and alive for a long time already otherwise.
Shard	832	Only OSS-Models	❌	Puzzy	Models	'Edgiest' API with a controversial/questionable environment. Normal service nowadays.
KrakenAI	735	Allowed	❌	PaniniCo	Models	Small, long-term stable API. Runs on https://poe.com

Tier 3 -- Experimental, Unstable, Open-Access AI APIs:

Service	# of Users1	NSFW/RP Ok?	Open Source?	Owner(s)	Models	Other Notes
ZanityAI	603	💰	❌	Voidii	Models	new api made by voidi (zj dev), fairly experimental but good.
ElectronHub	518	Use /nsfw/ instead of /v1/	❌	snowby666	Models	Created by the new poe-api-wrapper maintainer. Alleged KrakenAI copy.
Skailar	438	Forbidden	✅, Here	Aquadraws	Models	Ancient API at seemingly affordable cost. Service stability & maintainer interest is uncertain.
ShadowJourney	432	Forbidden	❌	ichatei	Models	Very weird owner. Unstable service & stability, when present, is questioned by supposed fake models. Use at own risk.
HeckerAI	237	Forbidden	❌	Hecker	Models	Solid API. Owner suffered from "Indecision to Keep Maintaining Syndrome" for a long time.
HareProxy	143	Allowed	✅, Here	yongdong	Models	A notorious pedophile holds a high ranking in the server. Good service otherwise.

Tier 3.5 -- Caution Advised: Questionable AI API Offerings:

Service	Why Potentially Misleading?	# of Users1	NSFW/RP Ok?	Open Source?	Owner(s)	Models
ClashAI	Conducted a coordinated raid on another AI API server.. API Owner is very petty (parked the entry of every api here) & begs for providers.	875	Allowed	❌	InvalidSian	Models
Stable, inc.	Conducted a coordinated raid on another AI API server.	849	Allowed	❌	alphast101	Models
AnyAI	Most influential person in the server is a terrible being.	1175	Allowed	❌	Meow18838	Models
CablyAI	Most influential person in the server is a terrible being.	674	Allowed	❌	CablyAI	Models

Tier 4 -- Potentially Misleading AI API Offerings:

Service	Why Potentially Misleading?	# of Users1	NSFW/RP Ok?	Open Source?	Owner(s)	Models
ShuttleAI	Now mainly focuses on own fine-tuned models, ignores "all other ones."	3635	Allowed	❌	tristandevs	Models
WebraftAI	Repeatedly accused of faking the top-tier models by even close associates to the owner. API Owner is MIA for weeks now. Service unavailable.	1207	Forbidden	❌	ds_gamer	Models
Pawan	Does not provide OpenAI models. Only provides own RP-Models.	108378	Allowed	❌	pawanosman	Models

Non-Tiered -- Non-API AI Servers:

Service	# of Users1	What does it provide?	Other Notes
FreeGPT4	4827	Ancient community of gpt-4-free individuals. Plenty good AI-related content.	Ran by @lomusire
g4f.ai	13339	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.
