Question 1

Which Hugging Face library provides pre-trained transformer models and tokenizers ready for fine-tuning or inference?

Accepted Answer

Transformers

Answer

The Hugging Face Transformers library provides thousands of pre-trained models and tokenizers for NLP, vision, and multimodal tasks.

Question 2

A developer needs to run inference on a 70B parameter model with limited GPU memory. Which technique reduces memory usage by representing weights in fewer bits?

Accepted Answer

Quantization

Answer

Quantization reduces the precision of model weights (e.g., from 16-bit to 4-bit), dramatically cutting memory requirements with minimal accuracy loss.

Question 3

What is the function of a 'system prompt' in chat-based LLM APIs like GPT-4?

Accepted Answer

It sets the model's behavior, persona, and constraints for the conversation

Answer

The system prompt in chat APIs provides initial instructions that define the model's role, tone, and rules for the entire conversation.

Question 4

Which cloud AI service allows consultants to deploy, version, and monitor custom ML models without managing underlying infrastructure?

Accepted Answer

AWS SageMaker

Answer

AWS SageMaker is a fully managed MLOps platform for building, training, deploying, and monitoring machine learning models.

Question 5

In the context of AI agents, what is the purpose of a 'tool' or 'function call' capability?

Accepted Answer

It enables the model to invoke external APIs or perform actions beyond text generation

Answer

Tool/function calling lets an LLM agent invoke external services, run code, or query databases, extending its capabilities beyond static text generation.
