This technical report describes DeepSeek-V3, a large language model with 671 billion parameters (think of them as tiny knobs controlling the model's behavior). DeepSeek-V3 uses a clever "Mixture-of-Experts" (MoE) approach, where only 37 billion parameters are active for processing each word, making it efficient and affordable to train. It's like having a team of experts where only the most relevant ones chime in for each task! DeepSeek-V3 excels in understanding and responding to instructions, performing well in tests like MMLU and DROP. It also shows remarkable abilities in math and coding challenges, beating other open-source models and sometimes even matching top closed-source models like GPT-4. The report explains the model's unique design and training process ...
