Local AI

Local AI is an AI model that runs on your own computer or phone instead of on a company's servers. Your data stays with you, and it often works without internet too.

With local AI, the AI model runs on your own device: a laptop, a mini computer or a phone. Your questions then do not have to go to a company's servers. It is like cooking at home instead of having a meal delivered: you need the kitchen yourself, but nobody else is looking over your shoulder.

How does it work?

An AI model is basically just a large file of numbers. If the model is open, anyone can download it and run it on their own hardware. The problem is size. The strongest models take up hundreds of gigabytes and normally only run in a data centre.

That is why models are often shrunk. A common way is quantisation: the numbers in the model are rounded off, so that the file becomes much smaller. This costs some accuracy. In addition, smaller models are made that are intended for a laptop or phone from the start.

Why it matters

Local AI gives control. Researchers, small companies and hospitals can use a model without sending their data elsewhere. And it also works when there is no internet. The company Gradium, for instance, released Phonon openly: small models that read text aloud in a natural voice, entirely on a phone, laptop or in the browser (link).

Ever larger models are coming within reach. DeepSeek's open model is well over 500 gigabytes, but the company Unsloth made a heavily shrunk version of it that runs on a powerful laptop or mini computer with 128 gigabytes of memory (link). The answer does come more slowly than from a chatbot in a data centre. There is something for the laptop when it comes to programming, too: the AI company Recursive released Flint, a free model that helps with coding. According to the company, its own research AI did a large part of the development work (link).
