DeepSeekとは？

DeepSeek is an AI platform developed by Hangzhou DeepSeek Artificial Intelligence Basic Technology Research Co., Ltd. It offers a suite of large language models (LLMs) such as the DeepSeek-V series, R1, and Coder, along with web, app, and API access. The platform is designed as a general-purpose AI assistant capable of natural language understanding and generation, extended context handling, reasoning, and code generation. It aims to compete with leading global AI models in both performance and cost efficiency.
