Question 1

What is AGI?

Accepted Answer

A hypothetical type of AI that can understand, learn, and apply knowledge across any intellectual task a human can perform.

Question 2

What is AI Agent?

Accepted Answer

An autonomous AI system that can perceive its environment, make decisions, and take actions to accomplish specific goals.

Question 3

What is API?

Accepted Answer

A set of rules and protocols that allows different software applications to communicate with each other.

Question 4

What is Chain-of-Thought?

Accepted Answer

A prompting technique that encourages a language model to break down complex reasoning into intermediate steps before arriving at a final answer.

Question 5

What is Deep Learning?

Accepted Answer

A subset of machine learning that uses neural networks with many layers to learn complex patterns from large amounts of data.

Question 6

What is Diffusion Model?

Accepted Answer

A type of generative AI model that creates images by learning to reverse a gradual noising process. DALL·E, Midjourney, and Stable Diffusion all use this approach.

Question 7

What is Embedding?

Accepted Answer

A numerical representation of text, images, or other data as a dense vector in a high-dimensional space. Embeddings capture semantic meaning.

Question 8

What is Fine-Tuning?

Accepted Answer

The process of taking a pre-trained AI model and further training it on a smaller, task-specific dataset to improve its performance.

Question 9

What is Foundation Model?

Accepted Answer

A large AI model trained on broad, diverse data that can be adapted to a wide range of downstream tasks. GPT-4, Claude, Llama, and Gemini are all foundation models.

Question 10

What is GPT?

Accepted Answer

A family of large language models developed by OpenAI that generate text by predicting the next token in a sequence.
