DeepSeek is an AI startup that has recently launched its latest model, DeepSeek-R1. This groundbreaking model demonstrates exceptional performance in mathematics, coding, and reasoning tasks, comparable to leading AI models like GPT-4. Notably, DeepSeek-R1 leverages reinforcement learning and fine-tuning with minimal labeled data to significantly enhance its reasoning capabilities. The most remarkable aspect of this development is that DeepSeek has fully open-sourced the R1 model under the MIT license, making it freely available for both commercial and academic purposes.
