What is DeepSeek? How Does DeepSeek Compare to ChatGPT in Performance?
What is DeepSeek?
DeepSeek is an emerging AI language model launched in January 2025, designed with a focus on efficiency and specialized technical problem-solving. Built using an innovative Mixture-of-Experts (MoE) architecture, DeepSeek activates only relevant parts of its vast network to reduce computational power while maintaining high-quality, logical responses. It is widely recognized for its strength in data retrieval, in-depth research, coding tasks, and domain-specific applications, offering transparency and customization for advanced users.
What is ChatGPT?
ChatGPT, developed by OpenAI and launched in 2022, is one of the most popular AI language models worldwide. Featuring a dense, transformer-based architecture with 1.8 trillion parameters, ChatGPT excels in producing versatile, conversational, and creative text across many languages. It is widely used for content creation, customer support, coding assistance, and more. ChatGPT offers a polished, user-friendly experience, including features like image generation and voice interaction.
Architectural Differences and Performance
DeepSeek utilizes a Mixture-of-Experts (MoE) model with 671 billion parameters but only activates a fraction during each query, leading to optimized resource use, faster processing speeds, and cost-effectiveness. Its reinforcement learning post-training enhances complex, chain-of-thought reasoning with logical structuring, making it ideal for technical and specialized queries.
In contrast, ChatGPT relies on a massive dense model designed for versatility across general knowledge, creative writing, and conversational applications. It provides rich, natural language output with broad language fluency, supporting multimodal input like text, voice, and images.
