DeepSeek, founded in 2023, is dedicated to researching the world's leading underlying models and technologies of general artificial intelligence and challenging the cutting-edge challenges of artificial intelligence. Based on self-developed training frameworks, self-built intelligent computing clusters, and tens of thousands of computing cards and other resources, the DeepSeek team has released and open-sourced multiple large models with hundreds of billions of parameters in just half a year, such as the DeepSeek-LLM general large language model and the DeepSeek-Coder code large model. And in January 2024, it was the first to open source the first domestic MoE large model (DeepSeek-MoE). The generalization effects of each major model outside the public evaluation list and real samples have all performed outstandingly, surpassing models of the same level.
