Under the Hood.
Ever nod along when someone says "API key" or "tokens" while quietly having no idea? Same. This is the back-end stuff nobody explains without making you feel dumb — models, APIs, tokens, what AI actually costs, and the difference between BYOK and a subscription. By the end it'll all feel obvious, and you'll never overpay (or get surprised by a bill) again.
By the end, you'll be able to
- Explain what a model, an app, and an API actually are
- Say what a token is — and why your long chats cost more & get dumber
- Get an API key and keep it safe
- Read how you're billed and dodge surprise charges
- Choose between free / BYOK / hosted like a pro
- Earn your Back-End Baddie certificate
