DeepSeek
FreeChina's open-source AI chatbot offering free access to powerful reasoning and coding models.
What is DeepSeek?
DeepSeek is a Chinese AI company offering free, open-source large language models that rival leading proprietary models at a fraction of the cost. Its web app at deepseek.com provides completely free access to DeepSeek V3 and R1 reasoning models with no subscription required. DeepSeek V3 excels at general-purpose chat and coding, while the R1 model uses chain-of-thought reasoning for complex math, logic, and programming tasks. For developers, the API is pay-as-you-go with some of the lowest token prices in the industry. The open-source nature allows self-hosting for organizations with data privacy requirements, though international data security concerns have been raised.
