Twenty-four AI models are free, and nobody is using them
There is no catch in the pricing column. There is a catch somewhere else, and it is the oldest one there is.

On a single price list of 446 models, twenty-four are priced at zero. Not a free trial, not a limited tier. Zero, in the column that says what a million tokens cost.
That is a genuine offer, and it is worth understanding why it exists.
Who pays for free
Running a large model costs real money — electricity, hardware, and a building full of graphics cards. Nobody absorbs that out of generosity at any scale.
So a free model is paid for in one of four ways:
As marketing. A lab releases a capable model at no cost to get developers using its tools and its format. The free model is an advertisement that happens to answer questions.
As a loss leader. A platform offers free access to one model to get you onto its platform, where the paid models sit one click away. You are the product being acquired.
For the data. The most direct arrangement, and the one to read the terms about. Free access in exchange for your conversations being used to improve future models. This is frequently disclosed, and frequently unread.
Because it is cheap to run. Some zero-cost models are genuinely tiny. Another company's electricity bill for serving them is close enough to nothing that giving them away costs less than advertising them.
What the catch actually is
It is rarely the model. It is usually what happens to your text after you send it.
A free tier that trains on your conversations means everything you paste — client documents, code, medical details, drafts — becomes training material. That is not a conspiracy. It is the stated price, and it is a fair trade if you understood it.
It also means free tiers are rate-limited in ways paid ones are not, which matters the moment you try to do something at volume.
How to use them well
Free models are the right choice for a great deal of work:
- Learning what a model can do, at no cost and with no commitment
- Bulk work on material that is not sensitive — public documents, your own notes, anything you would happily email a stranger
- Prototyping, where you need to find out whether an approach works before paying for it
- Comparing models, since a free tier is the cheapest way to find out which one suits your task
And the rule that covers the rest:
If you would not be comfortable seeing it in a training dataset, do not paste it into a free tier. That is a two-second test and it is right nearly always.
The part worth noticing
The existence of 24 free models is not generosity and it is not a trick. It is a market so competitive that giving away something expensive has become a rational way to buy attention.
Take the free models. Read the terms. Keep your private material off them.

Everyone calls it the same thing: using an AI model. The price list says these are not remotely the same product.
The two biggest AI models cost exactly the same
OpenAI's newest flagship and Anthropic's newest flagship are priced identically, to the cent. That is not a coincidence, and it tells you something about where the market has gone.
The Great Salad Oil Swindle
Inspectors measured the tanks with a tape dipped in water. Oil floats. One man used that fact to borrow against $150 million of soybean oil that did not exist.
