Uncertain chunks remain in a cache rather than being discarded. Across the reported DeepSearch benchmarks and models, QRAE improved task success by 2.35 percentage points on average while reducing latency by 30 percent and token use by 45 percent. The gains describe the tested systems, including one near 100 billion parameters.",
