Decide on Retrieval Based on Reasoning Steps
bigaiguy · x · 2026-07-11
This proposes Retrieval Timing Control: instead of retrieving just once at the start of a task, the system should evaluate at every reasoning step whether additional context is needed.
The agent first asks itself, "Do I have enough information to answer this sub-question?" If yes, it skips retrieval; if no, it initiates a new search. The author claims this single optimization reduced average token usage on multi-hop questions by 41%.
