Artificial Intelligence (AI) is a broad field focused on building systems that can perform tasks that usually require human intelligence: recognizing patterns, making predictions, optimising decisions, and learning from data.
To understand where AI is today, it's important to learn how we got here:

Many people use "AI" to mean generative AI tools like ChatGPT, but that's only one small part of AI. These are large language models (LLMs) and similar generative systems: they create text, images, and video based on patterns learnt from data. AI is broader: it includes many techniques that don't generate content at all and may run quietly in the background, making predictions, detecting anomalies, optimising decisions, or recognising images.
The diagram below shows the hierarchy of AI's different areas. AI has many more fields, but we focus on the main ones related to LLMs and ML:
A simplified overview:
A great introductory video to understand the history of AI and what is Machine learning, deep learning and LLMs in a very high level.

LLM stands for Large Language Model, a type of artificial intelligence system trained on vast amounts of text data to understand and generate human-like language. In HackYourFuture , you'll learn how to use LLMs as tools to assist in your learning.
3Blue1Brown offers an excellent explanation of how LLMs work. We hope it will give you more insight into how tools like ChatGPT can answer any question you ask.

Around minute 4:30, the video becomes technical about "Transformer models". Don't worry if you don't fully understand all the details.

Here are some of the most commonly used AI tools across different categories.
ChatGPT was the first widely available AI chatbot, but many other companies have since launched their own versions. We encourage you to explore different chatbots to find which one works best for you. Here are the current market leaders for high-quality chatbots:
Measuring the performance of an LLM is very difficult. Experts are actively researching this challenge. Some websites like Stanford's HELM leaderboard and LMArena try to collect statistics, but the task is incredibly difficult.
There is no single best LLM - it depends largely on your preferences and workflows.
