DeepSeek, an AI company spun off from the Chinese hedge fund High-Flyer in 2023, has gained attention for its unconventional open-source approach. Unlike major US AI firms like OpenAI and Google, which guard their models as trade secrets, DeepSeek builds powerful AI models cheaply and makes them openly available for developers to use, modify, and run on local servers. This challenges the belief that open-source AI lags behind proprietary models, positioning DeepSeek as a disruptive force in the AI landscape.
