Top Generative AI Interview Questions
1. What is Generative AI?
A: Generative AI is a branch of artificial intelligence that creates new content such as text, images, code, music, and videos by learning patterns from existing data.
2. How is Generative AI different from traditional AI?
A: Traditional AI mainly predicts or classifies information, whereas Generative AI creates entirely new content based on learned patterns.
3. What is a Large Language Model (LLM)?
A: An LLM is an AI model trained on massive amounts of text data to understand and generate human-like language.
Examples include GPT, Claude, Gemini, and Llama.
4. What are foundation models?
A: Foundation models are large pre-trained AI models that can be adapted for multiple downstream tasks through prompting or fine-tuning.
5. What is prompt engineering?
A: Prompt engineering is the process of designing effective prompts to obtain accurate, relevant, and high-quality responses from AI models.
6. What is tokenization?
A: Tokenization is the process of breaking text into smaller units called tokens before sending it to an AI model.
7. What is the difference between supervised learning and Generative AI?
A: Supervised learning predicts outputs from labelled data, whereas Generative AI learns patterns to generate entirely new content.
8. What are transformers?
A: Transformers are deep learning architectures that use attention mechanisms to understand relationships between words in a sentence.
9. What is self-attention?
A: Self-attention helps the model determine which words are most important while understanding the context of a sentence.
10. What is fine-tuning?
A: Fine-tuning is training a pre-trained model on a domain-specific dataset to improve performance for particular tasks.
11. What is Retrieval-Augmented Generation (RAG)?
A: RAG combines external knowledge retrieval with Large Language Models to provide more accurate and up-to-date responses.
12. Why is RAG preferred over fine-tuning in many projects?
A: RAG allows models to access current information without retraining, making it more scalable and cost-effective.
13. What is a vector database?

Examples include Pinecone, ChromaDB, Weaviate, and FAISS.
14. What are embeddings?
A: Embeddings are numerical vector representations of text or images that capture semantic meaning.
15. What is hallucination in Generative AI?
A: Hallucination occurs when an AI model generates incorrect or fabricated information while presenting it confidently.
16. How can hallucinations be reduced?
A: Hallucinations can be minimized using RAG, better prompting, fact verification, grounding with trusted data, and human review.
17. What is a context window?
A: The context window defines the amount of information an AI model can process in a single interaction.
18. What is temperature in AI models?
A: Temperature controls the randomness of responses. A low temperature produces more accurate answers, while a high temperature generates more creative responses.
19. What is zero-shot prompting?
A: Zero-shot prompting is a technique where you ask an AI model to complete a task using only instructions, without giving it any examples.
20. What is few-shot prompting?
A: Few-shot prompting includes a few examples before asking the model to perform a similar task.
21. What is chain-of-thought prompting?
A: Chain-of-thought prompting encourages the model to reason through complex problems step by step before producing an answer.
22. What is multimodal AI?
A: Multimodal AI can process multiple types of data such as text, images, audio, video, and documents simultaneously.
23. What is AI inference?
A: Inference is the process where a trained AI model generates predictions or responses for new inputs.
24. What is model fine-tuning versus prompt engineering?
A: Prompt engineering improves results by changing prompts, while fine-tuning updates the model's parameters using additional training data.
25. What are the most popular Generative AI frameworks?
A: Some widely used frameworks include:
- LangChain
- LlamaIndex
- Hugging Face Transformers
- OpenAI APIs
- CrewAI
- AutoGen
- Semantic Kernel
- LangGraph
