🚀 Generative AI Interview Questions with Answers (Part 3)
1️⃣1️⃣ What is a Context Window in an LLM?
👉 A context window is the amount of input and output text (measured in tokens) that an LLM can consider within a single interaction.
Example:
💡 A larger context window allows a model to work with more text, such as long documents or conversations.
---
1️⃣2️⃣ What is Temperature in Generative AI?
👉 Temperature is a parameter that controls the randomness of a model's output.
🔹 Lower Temperature → More predictable output
🔹 Higher Temperature → More varied output
Example:
💡 The ideal value depends on the task and model.
---
1️⃣3️⃣ What is Top-P in LLMs?
👉 Top-P, also called nucleus sampling, controls which candidate tokens are considered when generating text.
Instead of considering every possible next token, the model selects from a group of tokens whose combined probability reaches a specified threshold.
📌 Lower Top-P → More focused choices
📌 Higher Top-P → More diverse choices
💡 Temperature and Top-P are both generation controls, but they influence sampling in different ways.
---
1️⃣4️⃣ What is Zero-Shot Learning in Generative AI?
👉 Zero-shot learning means asking an AI model to perform a task without providing an example of the desired task in the prompt.
Example:
No translation example is provided.
💡 The model relies on patterns and capabilities learned during training.
---
1️⃣5️⃣ What is Few-Shot Learning?
👉 Few-shot learning means providing the AI model with a small number of examples in the prompt before asking it to perform the task.
Example:
The model can infer the expected pattern from the examples.
📌 Zero-Shot → No examples
📌 Few-Shot → Few examples

🚀 Generative AI Interview Questions with Answers (Part 4)
1️⃣6️⃣ What are Parameters in an AI Model?
👉 Parameters are the internal values learned by an AI model during training. They help the model learn patterns and relationships from data.
For example, neural networks learn parameters such as:
🔹 Weights
🔹 Biases
📌 Training Data → Learning → Parameters → Trained Model
💡 Generally, a larger number of parameters can allow a model to represent more complex patterns, but it also increases computational requirements.
---
1️⃣7️⃣ What is the Difference Between Fine-Tuning and RAG?
👉 Fine-Tuning changes a model's learned parameters by training it further on task-specific data.
👉 RAG keeps the model's parameters unchanged and provides relevant external information as context during generation.
📌 Fine-Tuning → Changes model behavior
📌 RAG → Provides external knowledge
Example:
Fine-Tuning: Teach a model a specific response style or task.
RAG: Let a chatbot answer questions using a company's latest documents.
---
1️⃣8️⃣ What is RLHF?

Basic process:
💡 Human feedback can help models produce responses that are more useful, relevant, and aligned with desired behavior.
---
1️⃣9️⃣ What is AI Safety?
👉 AI Safety focuses on designing and deploying AI systems in ways that reduce harmful, unreliable, or unintended behavior.
Important areas include:
🔹 Preventing harmful outputs
🔹 Protecting user data
🔹 Reducing bias
🔹 Improving reliability
🔹 Human oversight
🔹 Responsible deployment
💡 AI safety becomes especially important when AI systems are used in high-impact applications.
---
2️⃣0️⃣ What are AI Guardrails?
👉 AI Guardrails are rules, filters, validation mechanisms, or controls designed to keep an AI system's inputs and outputs within defined boundaries.
Examples:
🔹 Content Filtering
🔹 Input Validation
🔹 Output Validation
🔹 PII Protection
🔹 Tool Access Controls
🔹 Policy Enforcement
📌 User Input → Guardrails → AI Model → Guardrails → Output
💡 Guardrails help make AI applications more controlled, reliable, and safer.
