Lost in the Middle: How Language Models Use Long Contexts

Paper summary

Controlled question-answering and retrieval tasks show that relevant information is used unevenly across long contexts. Performance often falls when the needed material occurs in the middle rather than near the beginning or end.

Relevance to the project

Useful for testing whether F actually uses its bounded histories and slots. Vary relevant signal position instead of equating available capacity with functional access.

Language modelsLong-context processingEvaluation methods

Text-context effects need not transfer unchanged to local recurrent mechanisms.
