DeepSeek: A Cost-Effective Open-Source LLM Challenging ChatGPT

DeepSeek, an open-source large language model (LLM) developed by a Chinese AI research company, is challenging ChatGPT with its unique Mixture of Experts (MoE) architecture. Its efficiency comes from activating only necessary parameters, resulting in faster speeds and lower costs. Features like multi-head attention and multi-token prediction enable superior performance in long conversations and complex reasoning. Despite concerns about its data sources, DeepSeek's cost-effectiveness and direct output style make it a compelling alternative to ChatGPT.
