Learn about AI
Begin with the basics, then explore how today's AI systems are trained and used.
Understand the Basics
Start here to learn what AI is, how models work and where their limits lie.
What is artificial intelligence?
A starting point: what people mean by AI, what it can do and what it cannot do.
About 6 minutes
What is an AI model?
How a model turns an input into an output, using familiar examples rather than technical maths.
About 8 minutes

Training data, tokens, patterns and prediction — and why learning is not the same as human understanding.
About 10 minutes
Why AI matters
Where AI may be useful, where it can cause harm and why people should be able to question its use.
About 8 minutes
Skills, tools and agents
A practical comparison of an AI capability, a tool it can use and an agent that can take several steps.
About 7 minutes
Mistakes, bias and uncertainty
Why AI can be confidently wrong, repeat unfair patterns or give a different answer the next time.

Context, memory and retrieval
How an AI assistant uses the current conversation, saved information and retrieved documents.
About 10 minutes
How an AI model can be adapted
The difference between prompting, adding reference material and further training a model.
