Overview
LongCoT measures whether models can sustain coherent reasoning across long chains of thought. The… See the full description on the dataset page: https://huggingface.co/datasets/LongHorizonReasoning/longcot.Demeter-LongCoT-400K
Demeter-LongCoT-400K
Demeter-LongCoT-400K is a high-quality, compact chain-of-thought reasoning dataset curated for tasks in mathematics, science, and coding. While the dataset spans diverse domains, it is primarily driven by mathematical reasoning, reflecting a major share of math-focused prompts and long-form logical solutions.

MathSmith-HC-Solution-Generation-LongCoT-Qwen3-30B-A3BMathSmith: Towards Extremely Hard Mathematical Reasoning by Forging Synthetic Problems with a Reinforced Policy
Overview
This dataset is part of the MathSmith-HC Problem-Synthesizer collection, containing both questions and sampled answers (LongCoT setting).
It contains synthetically generated mathematical reasoning problems and their corresponding sampled solutions, produced through the reinforced problem generation pipeline described in the MathSmith framework.
