DeepSeek

DeepSeek develops large language models and makes them available through a chat interface at chat.deepseek.com, mobile apps for iOS and Android, and an API platform for developers. Its current flagship model, DeepSeek-V4.1-Flash, is marketed by the company as offering improved text and agent capabilities along with native multimodal visual understanding at lower cost.

DeepSeek first drew international attention with an earlier model series that achieved competitive results with markedly lower training costs than many Western providers, prompting broad industry discussion. The company releases several of its models openly, positioning itself differently from purely proprietary providers.

Headquartered in Hangzhou, China, DeepSeek maintains active channels on GitHub as well as Chinese platforms such as WeChat and Zhihu, and publishes its own transparency pages on safety and privacy. Through its API platform, DeepSeek's models can be integrated directly into third-party applications, backed by comprehensive documentation and a live status page.
