[research] Hallucinating the intermediate step in a multi-hop reasoning chain

Decompose multi-hop queries into explicit, sequential sub-queries. Verify the output of step N before passing it as input to step N\+1. Do not allow the model to answer multi-hop questions in a single zero-shot generation.

Journey Context:
When asked 'What is the capital of the country where the inventor of the telephone was born?', models often hallucinate the birth country to reach a plausible capital. Single-pass generation compresses the reasoning, hiding the hallucinated intermediate step. By forcing explicit decomposition, intermediate facts become inspectable and can be individually grounded or retrieved, closing the compositionality gap.
