Find out which AI models are free
Plenty of AI gateways give away some of their models, but the lists are scattered across their own pages and keep changing. AIGratis pulls them into one list that updates itself, so you know what you can use without paying today.
Once you outgrow the free tier, this site also lines up per-token prices from every gateway in a single table. The units differ and the currencies are mixed, so comparing them yourself means opening a dozen tabs and doing the arithmetic. That part is our job.
How the numbers are collected
- 01
Pull from the official API
Every 6 hours we call each gateway's model-list endpoint with our own API key. No number here is retyped from a screenshot.
- 02
Normalise the units
Some gateways quote per token, some per thousand, some per million, in USD or in Rupiah. Everything is converted to one unit so the figures are genuinely comparable.
- 03
Merge model names
anthropic/claude-opus-5 and claude-opus-5 are the same model. They are merged into one row so you can see every gateway that serves it at once, including the ones giving it away.
A few gateways do not expose prices through an API. For those we fill the prices in by hand from their official pages and mark them so a sync cannot overwrite them. Prices can change at any time, so always check the gateway's own page before you pay.
Who works on this
Adam Suchi Hafizullah
I build and maintain this site myself. It started as a habit of opening a dozen tabs just to work out which gateway was cheapest for one model. Got feedback, spotted a wrong price, or want a particular gateway tracked? Say hello through the links beside this.
How this is funded
Some sign-up buttons carry our referral code. If you sign up through one, we earn a small commission from the gateway and what you pay stays exactly the same. That is what funds the API keys, the server, and the daily data refresh.
What we do not do: reorder the table for commission. The order is always cheapest first, including for gateways that give us nothing.
