Model
A trained system that maps inputs to predictions or outputs; in this glossary, usually a generative language model.
Illustrative conversation
- Can the model open our repository by itself?
- No. The harness must expose a filesystem tool; the model only decides when and how to request it.
Definition
A model is a trained component that maps inputs to outputs. Here the term usually means an autoregressive language model; not all AI models generate text or predict the next token. In an agent, it supplies language understanding, reasoning, and decisions, but it does not provide the whole system: the surrounding harness supplies instructions, context, tools, and permission boundaries.
