AI trends and technical foundations
Why everyone talks about LLMs—and how they actually “read” language.
Students meet chat interfaces daily but rarely separate generative AI from traditional programmes. This unit clarifies the trend, then returns to tokens, training data and why hallucinations appear.
The goal is not jargon drills. Students should say in their own words what an LLM is good at, where it fails, and how to check outputs.
- How generative AI differs from traditional programmes: rules versus probabilistic generation
- Tokens, training data, hallucinations: why AI can be wrong and answers must not be trusted blindly
- From ChatGPT to core large-language-model ideas: shared principles behind the interface
