The AI stack
When you press send in a chat app, your question passes through at least five companies' worth of technology before a word comes back. Which layers are they, and which one will you build?
In this lesson you'll learn to
- Name the layers of the AI stack, from hardware to product, and what each one does.
- Say who builds each layer, and which layers AI engineers spend their time in.
- Weigh calling a model through an API against running an open-weight model yourself.
- Estimate how much GPU memory a model needs from its size, and explain why that pushes most teams to APIs.
