Claims

C1strongest claim

on challenging benchmarks such as AIME 2025, DeepConf@512 achieves up to 99.9% accuracy and reduces generated tokens by up to 84.7% compared to full parallel thinking.

C2weakest assumption

That model-internal confidence signals reliably indicate the quality or correctness of individual reasoning traces, allowing effective dynamic filtering without additional training or tuning.

C3one line summary

DeepConf filters low-quality reasoning traces using model-internal confidence signals, reaching up to 99.9% accuracy on AIME 2025 while reducing generated tokens by up to 84.7% versus full parallel sampling.
