More words in How it works
- World modelAn AI's internal sense of how the world works, which lets it predict what will happen next. Seen as important for robots.
- Agent harnessThe software wrapped around a model that lets it act as an agent. It manages the to-do list, the tools, the memory and the permissions.
- AttentionThe trick inside modern AI that lets it weigh which words in a sentence matter most to each other, so it keeps track of meaning.
- BackpropagationThe way a neural network learns from its mistakes: it works out how wrong it was, then nudges its internal dials to be less wrong next time.
- Chain of thoughtWhen an AI works through a problem step by step before giving its answer, which usually makes it more accurate.
