AI is the broad field of building systems that perform tasks normally requiring human intelligence. Generative AI is one specific capability within that field — producing new content. Every generative AI system is AI; most AI systems are not generative.
The Umbrella Relationship
Artificial Intelligence (AI)
└── Machine Learning (ML)
└── Deep Learning (DL)
└── Generative AI
├── LLMs (text)
├── Diffusion models (images)
└── Speech models (audio)This nesting matters — it's the basis for the next two comparison notes (vs ML and vs DL).
Non-Generative AI — Real Examples
| System | Task | Generative? |
|---|---|---|
| Spam filter | Classify email as spam/not spam | No — discriminative |
| Fraud detection model | Score a transaction's risk | No — discriminative |
| Recommendation engine | Rank products by relevance | No — discriminative/ranking |
| ChatGPT | Produce a written response | Yes — generative |
| Chess engine (e.g. traditional minimax-based) | Select the best move | No — search/decision-based, not content generation |
Why This Distinction Matters Practically
"We're adding AI to our product" is vague. "We're adding an LLM-based summarization feature" tells you the actual engineering tradeoffs: cost per request, latency, hallucination risk, prompt design — none of which apply the same way to a simple classification model. Precision in this vocabulary avoids miscommunication with engineering teams and stakeholders.
Common Mistakes
- Calling any AI-powered feature "generative AI," even when it's a classifier or recommender under the hood
- Assuming generative AI is a strict upgrade over other AI approaches — for tasks like fraud scoring or ranking, a discriminative model is usually more accurate, cheaper and faster
Interview Relevance
"Is a recommendation system generative AI?" is a good screening question — the correct answer is no (it ranks/selects from existing items rather than producing new content), and explaining why signals real conceptual clarity.
Practice Question
A company says they use "AI" for three features: résumé screening, an internal chatbot, and search-result ranking. Which, if any, are generative AI?
