Dolphin-R1 is a dataset created by the Cognitive Computations team in 2025 to provide high-quality samples for training inference models similar to DeepSeek-R1. The dataset contains about 800,000 samples, and the data sources include 200,000 samples provided by DeepSeek-R1, Gemini Flash, and Dolphin Chat. These samples are mainly used to improve the performance of the model in reasoning tasks, covering complex tasks such as mathematics, logic, and coding.
