Ever wondered how AI replies in just seconds? Let’s understand the real engine behind its speed — the GPU.

In Day 6 of our 100-Day Free AI Learning Challenge, we explain how AI achieves its incredible speed.

Using a simple shop analogy, this session shows how an LLM’s patterns are kept in permanent storage — the “basement.” But answering directly from there would be slow. So when the AI runs, its patterns move from the basement into the GPU’s fast memory (VRAM) — like moving stock to a busy market shop.

You’ll learn what a GPU (Graphics Processing Unit) really does, why it can perform thousands of calculations at once, and how this makes AI generate answers almost instantly. Simple Hinglish explanation for beginners.
