Plain-Language Definitions
AI Agent
An AI system that decides on its own which tool to call, checks what it gets back, and repeats that loop — planning and acting across multiple steps — rather than just replying once to a single message.
Context Window
The maximum amount of text — measured in tokens, not words — that a model can hold in view at once, including everything you've said in the conversation so far, any documents you've pasted in, and the reply it's generating.
Fine-tuning
Additional training applied to an already-built model, using your own examples, so it consistently adapts to a specific task, tone, or format — different from prompting, which shapes a single response rather than the model's underlying behavior.
Hallucination
When a model states something confidently that isn't true — not because it's lying, but because it always generates the most statistically plausible next words, and plausible isn't always the same as correct.
Large Language Model (LLM)
An AI model trained on an enormous amount of text, built to predict the most likely next word given everything written so far — that single mechanism, repeated, is what produces writing, code, and conversation that reads as fluent and often accurate.
Prompt
The instruction you give a model — in plain language — to tell it what you want produced. It can be a single sentence or several paragraphs, and its wording shapes the output far more than most people expect.
