Can you build your own AI model? The answer depends on who it’s for. Let’s understand what it really takes — from a home setup to massive data centers.

In Day 7 of our 100-Day Free AI Learning Challenge, we answer this common question.

If you want a small model with fewer parameters — for personal use or a small community — yes, you can even build it at home by buying a GPU. But if you want a model the whole world can use, that’s a different story. It needs not one or two, but thousands of GPUs.

This session explains why big AI models require massive data centers — with special cooling systems (because thousands of GPUs generate huge heat), enormous electricity, and GPUs that cost lakhs of rupees each. You’ll understand the real infrastructure and cost behind building large-scale AI. Simple Hinglish explanation for beginners..
