Frequently Asked Questions about DeepSeek
- What are the differences between DeepSeek and ChatGPT?
- Research Background and Technical Features: DeepSeek is developed by the Chinese DeepSeek team and employs a Mixture of Experts (MoE) architecture, combining the advantages of multiple expert models to dynamically select the most suitable expert model for processing, making it suitable for complex tasks. ChatGPT, developed by OpenAI, is based on the Transformer architecture, supports multimodal input, and has powerful natural language processing capabilities to simulate human dialogue.
- Functions and Application Scenarios: DeepSeek performs well in vertical fields such as finance, healthcare, and code generation, supports private deployment, and can integrate with corporate knowledge graphs, making it suitable for enterprise-level applications. ChatGPT is suitable for a wide range of text generation and dialogue tasks, providing creative inspiration and supporting functions such as voice recognition, and is widely used in education, customer service, and other fields.
- Chinese Processing Capability: DeepSeek has been deeply optimized for the Chinese context and can better understand Chinese grammar and cultural background, making it more suitable for Chinese users. Although ChatGPT supports multiple languages, its Chinese processing is not as idiomatic as DeepSeek.
- Cost and Deployment: DeepSeek has lower training and inference costs, supports local deployment, and reduces hardware requirements by 60%, making it suitable for resource-limited enterprises. ChatGPT has high training costs and requires powerful computing support, making it suitable for users and organizations with ample resources.
- Open Source and Ecosystem: DeepSeek's open-source strategy has attracted many developers to participate in optimization and customization, promoting the popularization and application of technology. ChatGPT is mainly led by OpenAI and covers global developers and enterprise users through APIs and ecosystem cooperation.
- What is the training cost of DeepSeek?
- DeepSeek uses FP8 mixed-precision training to significantly reduce GPU memory requirements and storage bandwidth pressure during the training process. For example, when training DeepSeek-V3, using FP8 precision compared to traditional FP16 or FP32 precision can reduce GPU memory usage by about 50%. Additionally, its efficient training mechanism allows the model to complete pre-training in less than two months.
