DeepSeek AI: The Rise of Cost-Effective Open Source LLMs

DeepSeek, a Chinese AI company led by entrepreneur Liang Wenfeng, has launched its AI chatbot, DeepSeek R1, which claims superiority over major chatbots like OpenAI's ChatGPT, Meta's Llama, and Google's Gemini Advanced. Notably, DeepSeek's development was significantly more cost-effective, with a reported training cost of $5.6 million compared to the billions spent by American competitors, and its open-source nature allows for broad accessibility and modification. Despite its impressive performance and efficiency, DeepSeek faces criticism for its censorship of politically sensitive topics, although companies like Microsoft have integrated it after removing these restrictions. The launch has caused significant disruption in financial markets, notably impacting NVIDIA's valuation, and its rapid popularity is evident as it became the most downloaded app in the US shortly after its release. DeepSeek uses a "Chain of Thought" model to improve reasoning and transparency, showing its thought process step-by-step, but it has been accused by OpenAI of copying its AI model through distillation. Its use of a Mixture of Experts method makes it efficient and further enhances its cost-effectiveness, making AI more accessible and practical for developers and researchers.
