    Tips & Tricks

    • You don't need to code to understand AI — focus on concepts and mental models
    • Think of neural networks as pattern-recognition machines, not 'brains'
    • The transformer architecture is behind nearly every modern AI tool — understanding it is key
    • AI 'training' is like teaching by example — the more quality examples, the better the model
    • Every AI tool you use (ChatGPT, Midjourney, etc.) is built on these same fundamentals
