AI Development Concepts

The smallest unit of text that an LLM processes, roughly equivalent to three-quarters of a word in English or 3 to 4 characters of code. Tokens determine context window capacity, output length, and per-request cost.

The foundational feature of AI coding tools that predicts and suggests code as you type, ranging from single-line tab completions to multi-line block suggestions based on the surrounding file and project context.

A neural network trained on massive text and code datasets that predicts and generates text token by token, forming the engine behind every AI coding tool from autocomplete to autonomous agents.
