DeepSeek AI is an advanced research company and developer of a family of powerful large language models (LLMs), many of which are available open-source. DeepSeek's primary focus is achieving high performance in areas such as code generation and understanding, mathematical reasoning, and instruction following. The company has released two main model lines: DeepSeek-LLM (general-purpose models for dialogue and text generation) and DeepSeek-Coder (models specifically trained on a vast corpus of code and mathematical data). DeepSeek-Coder models, trained on 2 trillion tokens of code and text, demonstrate outstanding results on coding benchmarks like HumanEval and MBPP, often surpassing other open-source and even some closed-source models. They support a wide range of programming languages and are capable of generating code, completing it, explaining it, and assisting with debugging. The general-purpose DeepSeek-LLM models also show strong performance in general tasks and dialogue. A key advantage is the open-sourcing of many models (e.g., DeepSeek Coder 33B, DeepSeek LLM 67B) under permissive licenses (Apache 2.0 or a custom license allowing commercial use), enabling the community to freely use and fine-tune them. Models are available for download via Hugging Face and other platforms. DeepSeek also offers access to its models through its own API platform with competitive pay-as-you-go pricing. DeepSeek models are used for building AI coding assistants, chatbots, data analysis tools, and other applications requiring powerful language capabilities.
