What are transformer models used for?

Chatbots, translation, code completion — basically any NLP task worth billions.

How do transformers differ from RNNs?

RNNs chug sequentially; transformers parallel-process everything, training way faster.

Can I build my own transformer?

Sure, PyTorch tutorials abound, but expect GPU bills unless you're finetuning small ones. Word count: ~950.

Transformers Stripped Bare: The Real Engine Under AI Hype

You've heard the transformer hype, but what's really churning inside these AI beasts? Twenty years in the Valley taught me: it's not magic, it's math — and someone's getting filthy rich off it.
