Faithfulness
The property of a generated answer whose every claim is supported by the retrieved context — regardless of whether those claims are true of the world.
-
Query Rewriting
Transforming the query the user typed into one or more different queries before searching, because the original is often a poor search input.
-
Context Window
The maximum amount of text, measured in tokens, that a language model can process in a single request — input and output together.
-
Reranking
A second scoring pass that reorders an already-retrieved candidate set using a slower, more accurate model that reads query and document together.
-
Hallucination
Model output that is presented as fact but is not supported by the supplied sources or by anything else — fluent, confident, and unfounded.
-
Grounding
Tying a model's output to specific supplied source material, so each claim in the answer traces back to text the system provided rather than to training.
-
Token
The unit of text a language model actually processes — a word, word-fragment, or character sequence produced by that model's tokeniser.
