Overview
DeepSeek is a Chinese AI lab whose fully free chat app and open-weight models shook the AI market. The V3 series handles general chat while R1 models specialize in reasoning and expose their full chain of thought; a DeepSeek-V4 preview promising stronger agent abilities has been announced. The models excel at coding and math, API pricing is a fraction of comparable GPT or Claude rates, and the weights are openly published on GitHub for self-hosting. The app is free on web, iOS and Android. Main caveats: data is stored on servers in China, and there is no built-in image or video generation.
