Bypassing inference bottlenecks: Accelerating complex AI search with Retrieve-for-Train
Retrieve-for-Train moves reward-guided query exploration offline, then distills it into a 53.9M-parameter diffusion retriever that generates a complete target set in one non-autoregressive pass.
Why it matters: For production search, the framework shifts expensive reward-guided exploration out of the user-facing inference path. The article reports sub-second to a few seconds for Retrieve-for-Train-Diffusion at scale, versus nearly 50 seconds for autoregressive fan-out under large context batches.
