ChatGPT, developed by the U.S. company OpenAI, is a conversational system based on the GPT (Generative Pre-trained Transformer) architecture. Since its release in 2022, ChatGPT has rapidly gained popularity and become a global tool. The GPT-4 model of ChatGPT excels in language understanding and creative generation. Its training costs are relatively high, with GPT-3 costing around $1.4 million and GPT-4 ranging from $2 million to $12 million. Additionally, ChatGPT’s annual operational cost in 2023 was about $475 million.<\/p>\n\n\n\n
DeepSeek vs ChatGPT: Core Technical Comparison<\/h2>\n\n\n\n
DeepSeek and ChatGPT differ significantly in terms of their technical capabilities, resulting in distinct user experiences.<\/p>\n\n\n\n
Model Architecture & Efficiency<\/h3>\n\n\n\n
DeepSeek uses a Mixture-of-Experts (MoE) architecture, where only a subset of specialized experts is activated for each task, making it more efficient in terms of computational resources and cost. It activates fewer parameters (about 37 billion out of 671 billion) for each query, resulting in lower energy usage<\/strong>. However, this type of model means that DeepSeek may not be as flexible or stable as ChatGPT when handling very complex or cross-domain tasks.<\/p>\n\n\n\n In contrast, ChatGPT uses a transformer architecture<\/a> where the entire model is activated for every task, ensuring consistent performance but with higher resource consumption and operational costs. This makes ChatGPT less efficient compared to DeepSeek, especially for tasks that don\u2019t require the full power of the model.<\/p>\n\n\n\n Compared to ChatGPT, DeepSeek gives you a more accurate and direct answer in technical tasks.<\/p>\n\n\n\n With the MoE architecture and large data train, DeepSeek is highly specialized in coding, math, and reasoning. In coding, DeepSeek is pre-trained on 2 trillion tokens in more than 80 programming languages, including Python, Java, C++, etc. This enormous training pool helps DeepSeek gain higher accuracy than ChatGPT.<\/p>\n\n\n\n On the other hand, ChatGPT is a versatile AI with strong general-purpose capabilities. It can be considered as a teacher who tries to make you learn about the principle. While it can finally give you an accurate answer, you might think it talks too much.<\/p>\n\n\n\n Both DeepSeek and ChatGPT are good at writing. However, DeepSeek is slower than ChatGPT in answering. I give the same prompt to DeepSeek R1 and ChatGPT 4o, and 4o responds in 1 second while R1 thinks for about a half minute. Meanwhile, ChatGPT doesn\u2019t finish the story at once; it will ask you what the end you want. But both the R1 and 4o models\u2019 stories are good.<\/p>\n\n\n\n As for multimodal abilities, DeepSeek can only analyze an image and a text file. However, it doesn\u2019t support creating images. ChatGPT can analyze and create audio, images, and texts.<\/p>\n\n\n\n According to DeepSeek\u2019s official news<\/a>, its 6 small models are open-source and free. Users can experience them on Chat.DeepSeek.com<\/a> and its app version.<\/p>\n\n\n\n ChatGPT, accessible via web UI and API, offers a free version suitable for everyday use. The ChatGPT Plus version costs $20 per month, unlocking GPT-4 for faster performance and more capabilities. The Pro version is $200 per month, providing even more advanced features. While the free version is sufficient for basic tasks, the paid versions offer more efficient and professional tools, especially for complex tasks and creative needs.<\/p>\n\n\n\n Related:<\/strong> Gemini vs ChatGPT: Which One Is Better?<\/a><\/p>\n\n\n\n Is DeepSeek better than ChatGPT? For now, DeepSeek still has some ground to cover before fully catching up with ChatGPT. However, it has proven to be highly capable in technical fields, as reflected in its global user base and reviews.<\/p>\n\n\n\n Both DeepSeek and ChatGPT are widely recognized AI tools that have garnered significant attention. DeepSeek, being open-source and free, is especially popular among developers and researchers in China. It excels in specialized fields such as finance and biomedical research, often surpassing ChatGPT in accuracy. However, concerns about data security and privacy, particularly when handling sensitive information, remain a topic of discussion.<\/p>\n\n\n\n On the other hand, ChatGPT has built a strong global presence thanks to its ability to generate smooth, natural conversations. It performs exceptionally well in general tasks and everyday interactions, but may not be as precise as DeepSeek in highly technical areas.<\/p>\n\n\n\n Community discussions, particularly on Reddit, highlight this divide\u2014while the majority of users still favor ChatGPT for its versatility and ease of use, some technical users find DeepSeek better suited to their specific needs.<\/p>\n\n\n\n Tip:<\/strong><\/p>\n\n\n\n If you worry about the safety of using an AI tool, try LightningX VPN<\/a>.
