Lesson 6: Behind the Scenes
Local AI Models
When you use an AI like Lumen or ChatGPT, your question travels to a massive data centre on the other side of the world.
There is another way to run LLMs right on your own device. These are called local models.
To run a model locally you need to be able to download it. This is why all local models are also open weight.
Not all open source models are local; you can run an open weight model on a cloud server.
Llama is the most famous local LLM but there is also Gemma by Google, Phi by Microsoft and Mistral and DeepSeek.
