Report #57919

[research] When asked a question requiring combining two facts, the model fabricates the intermediate step rather than retrieving both facts

Decompose multi-hop queries into explicit, sequential sub-queries. Execute the first query, extract the specific answer, and use that extracted string as the input for the second query.

Journey Context:
LLMs struggle with latent multi-hop reasoning. If the intermediate entity is not highly prevalent in the training data, the model will guess or hallucinate it, leading to a cascading factual error. By forcing the model to output the intermediate result and feed it back in \(Iterative Retrieval / ReAct pattern\), you ground each step independently, preventing the cascade.
