Reasoning Models Can Be Effective Without Thinking

no code implementations14 Apr 2025 Wenjie Ma, Jingxuan He, Charlie Snell, Tyler Griggs, Sewon Min, Matei Zaharia

Building on this observation, we demonstrate that a parallel scaling approach that uses NoThinking to generate N outputs independently and aggregates them is highly effective.

On Distribution Shift in Learning-based Bug Detectors

1 code implementation21 Apr 2022 Jingxuan He, Luca Beurer-Kellner, Martin Vechev

To address this key challenge, we propose to train a bug detector in two phases, first on a synthetic bug distribution to adapt the model to the bug detection domain, and then on a real bug distribution to drive the model towards the real distribution.
