arXiv:2606.02113v1 Announce Type: new Abstract: Post-training has become a primary driver of recent progress in large reasoning models, and reasoning data are often the key variable determining whether this stage succeeds. Work on post-training reasoning data has grown rapidly, yet this literature remains scattered across dataset papers, reinforcement-learning recipes, reward-model studies, benchmarks, and frontier system reports. This paper is the first primer to synthesize over 150 key public studies and system reports on post-training reasoning data. We organize the field around four questi
This paper synthesizes a rapidly growing and scattered body of work on post-training reasoning data, providing a timely overview of best practices and gaps in a critical AI development area.
Understanding how reasoning data shapes large models is crucial for anyone involved in AI development, investment, or policy, as it directly impacts model capabilities and future AI progress.
The publication provides a structured framework for assessing and improving reasoning data, potentially accelerating advancements in AI model performance and application.
