Some companies give you artificial intelligence only through their own door, for money every time. Others hand out the whole machine for free: you download it to your own computer and do whatever you want with it. The difference is called open and closed model, and behind it stands not generosity, but a calculation about power.
The Owner's Door
OpenAI (the company behind ChatGPT), Anthropic (the company behind Claude) and Google give access to their strongest models in one way: through their own website or their own programming interface. You pay for every query. The model never sits on your computer. You don't see what's inside, you can't take it apart, you can't copy it and take it elsewhere.
It's like a table in someone else's restaurant. You sit down, you order, you get used to the taste. But the kitchen isn't yours. The owner can raise the price tomorrow, change the menu, tell you he no longer serves your line of business. You have access to the table, not to the kitchen.
The Recipe for Free
The other path is different. Meta (the company behind Facebook and Instagram) publishes its Llama model and anyone can download it from the internet. The Chinese company DeepSeek does the same. So does Alibaba, owner of the model Qwen. You download the files, run them on your own machine or a rented server, and from then on you owe no one anything for each query. You can change it, train it on your own documents, lock it behind your own door, and your customers might not even find out whose model is underneath.
It's like a cook who gives you the recipe for the dish as a gift. Not a restaurant. He gives you the recipe itself. You cook it yourself, with your own ingredients, in your own kitchen. No one comes to check what you're cooking inside.
Why Someone Gives Away Blueprints for Free
This is the moment a question mark lights up for you too, and rightly so. Why would a company that spent money building something expensive then give it away? The answer is a plain calculation about position in the race.
Meta doesn't sell access to artificial intelligence as its main business. It sells advertising. It's more profitable for the world to build on its blueprints than on the blueprints of OpenAI or Google. The more developers get used to Llama, the harder it will be for them to switch to a competitor. That's why the license is free with one agreed exception: if your product passes seven hundred million monthly users, you have to negotiate separately. In other words: you give it away to everyone except the ones who'd become big enough to compete with you.
DeepSeek and Alibaba have a different calculation. They're chasing Google and OpenAI from outside, not from inside. They can't win the battle by the rules the US sets. So they change the game: they make theirs free and available everywhere, including offline, including in places where Western models are banned or expensive. If the whole world gets used to building on their foundations, the American advantage becomes less significant, even if they haven't sold a thing.
Here's the Difference
To me, which model is open isn't a moral question about good and bad companies. I see it as a race for whose infrastructure becomes the default. Just like one accounting program became the standard - because everyone around you was already using it and it was cheaper for you not to break away, not because it was the best.
Both kinds hide something. The closed one hides how the machine thinks. The open one hides what data it was trained on. No one gives that up, even when handing out everything else. So "open" here doesn't mean transparent. It just means you can keep it with you, without running a tab in someone else's restaurant every month.
For a small company this is a real choice with real consequences, not a philosophical debate. If you put a closed model at the base of an important process, you depend on someone else's kitchen: someone else's price, someone else's menu, someone else's rules going forward. If you put in an open one, you take on a different responsibility. You cook it yourself, you guard the recipe yourself, and you answer for it yourself if something burns. Freedom with no restaurant behind your back, but also no cook who comes running when something goes wrong.
