The Vocabulary They Test

Every entry exam starts here. Learn the hierarchy cold:

• AI — the whole field: machines doing things we'd call intelligent (rules, search, learning — all of it)
• Machine learning (ML) — inside AI: systems that learn from data rather than follow hand-written rules
• Deep learning — inside ML: neural networks with many layers
• Generative AI (GenAI) — inside deep learning: models that produce new content — text, images, audio, code

All GenAI is deep learning; all deep learning is ML; all ML is AI. The exams test whether you can sort a claim into the right doll.
