Oops, Wait: Discourse Tokens Matter in Reasoning Model

arXiv:2601.17421v2 Announce Type: replace Abstract: Recent studies suggest that even data-efficient training with ($\simeq$1K) reasoning trajectories can induce non-trivial reasoning capabilities in large language models through post-training. Such training corpora often contain iconic tokens such as "wait", "so", and "alternatively", which frequently appear in reasoning trajectories and may play a role in this process. This paper focuses on characterizing observable token-level patterns in post-training and a case study of how data-efficient supervised fine-tuning (SFT) differs from, and fall

Why this matters
Why now

The paper builds on recent discoveries that data-efficient training can induce reasoning capabilities in large language models, focusing on specific linguistic elements observed in these training processes.

Why it’s important

Understanding the role of discourse tokens can lead to more efficient and effective training methodologies for reasoning in AI models, impacting the development trajectory of advanced AI.

What changes

This paper highlights specific token-level patterns, such as 'wait' or 'so', directly influencing AI reasoning capabilities through post-training, potentially refining current fine-tuning practices.
