Summary
Mixture-of-Thoughts is a curated dataset of 350k verified reasoning traces distilled from [DeepSeek-R1](https://huggingface.co/deepseek-ai/DeepSeek-R1). The dataset spans tasks in mathematics, coding, and science, and is designed to teach language models to reason step-by-step. It was used in the Open R1 project to train [OpenR1-Distill-7B](https://huggingface.co/open-r1/OpenR1-Distill-7B), an SFT model that replicates the reasoning capabilities of [deepseek-ai/DeepSeek-R1-Distill-Qwen-7B](https://huggingface.co/deepseek-ai/DeepSeek-R1-Distill-Qwen-7B) from the same base model.
