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

Warning

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 APIs¹

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

Tier 1 — Established, Premium-Service AI API Leaders

Service	# of Users	NSFW/RP Ok?	Open Source?	Owner(s)	Models	Other Notes
zukijourney	6,588	✅ Allowed	✅ Here	ZJ Team	Models	The undisputed leader of the AI APIs, the largest & oldest of its kind still running. Offers other popular AI-related bots too.
ElectronHub	1,851	✅ Use /nsfw/ instead of /v1/	❌	snowby666	Models	Developed by the maintainer of the poe-api-wrapper. Very RP-friendly. Did not ban 'his friend' who generated CP with his bot.
ZanityAI	985	💰 Paid models only	❌	Voidii	Models	A roleplay-friendly API led by the Zukijourney CMO. Ran on a stolen ZJ codebase for a pretty long time.

---

Tier 2 — Standard, Basic AI API Services

Service	# of Users	NSFW/RP Ok?	Open Source?	Owner(s)	Models	Other Notes
NagaAI	3,363	❌ Forbidden	❌	ZentixUA	Models	Honorary successor to ChimeraGPT, the largest g4f API in history (16k users).
HelixMind	1,279	❌ Forbidden	❌	faer1x	Models	Subscription-based service that 'just about' fits into the g4f principles definition with its free tier.
WebraftAI	1,268	❌ Forbidden	❌	ds_gamer	Models	Recovered from 5-month downtime due to the owner's health issues. Some instability in current service.

---

Tier 3 — 'Inconsistent' APIs

Service	# of Users	NSFW/RP Ok?	Open Source?	Owner(s)	Models	Other Notes
XET	1,167	✅ Allowed	✅ Here	alphast101	Models	Conducted a coordinated raid on another AI API server.
ClashAI	1,004	❌ Forbidden	❌	Sian	Models	API that came back after 'teasing' its re-release for multiple months.
NexeonAI	190	❌ Forbidden	❌	Sakuya	Models	API with an inconsistent maintainer commitment and mental health.

---

Tier 4 — Experimental, Unstable, Open-Access APIs

Service	# of Users	NSFW/RP Ok?	Open Source?	Owner(s)	Models	Other Notes
Skailar	463	❌ Forbidden	✅ Here	Aquadraws	Models	One of the oldest APIs. Stability and maintainer involvement are questionable.
VoidAI	305	✅ Limited	❌	acatto	Models	An odd api with historically some other ai-related projects. Now focused on just APIs it seems.
HareProxy	261	✅ Allowed	✅ Here	yongdong	Models	Offers unique endpoints for each model type. Owner self-proclaimes to be unable to code.

Tier 5 -- Caution Advised! Questionable AI API Offerings

Service	# of Users	NSFW/RP Ok?	Open Source?	Owner(s)	Models	Why Potentially Misleading?
ShadowJourney	797	❌ 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.
KrakenAI	731	✅ Allowed	❌	KrakenAI	Models	Owner has an odd agenda against me (zukixa). Multiple of my accounts are banned from the server, so I cannot reliably confirm how good the service is, but I am ware of it existing.
CablyAI	602	✅ Allowed	❌	CablyAI	Models	De-Facto Owner is a subhumanely terrible being.

Non-Tiered -- Non-API AI Servers:¹

Service	# of Users	What does it provide?	Other Notes
g4f.ai	12,597	Hub of the github repository that started it all.	Not very active, nor really moderated.
NexusAI	5,033	Continuation of an older project. Provides UIs for image and ai text generation.	Moonman/Pushkar is a known credit card fraudster and self-advertised his projects in many places before.
FreeGPT4	4,832	Ancient community of gpt-4-free individuals. Plenty good AI-related content.	Ran by @lomusire
SpyrkAI	661	The first "g4f" AI Labs. Slow at work, but may produce cool things at some point.	Also a very inactive server.
Personality.GG	46	Upcoming ai character roleplay website.	The new project of ex-Tier-1 API (Shard)'s owner.

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.
