DeepSeek vs ChatGPT: Key Differences You Should Know
I have been using ChatGPT for a long time, and I’m very impressed with this chatbot—especially its ability to converse like a human and respond with incredible speed. ChatGPT marks the beginning of AI technology, but now, a new chatbot, DeepSeek, has emerged as a strong competitor.
DeepSeek is a large language model with unique capabilities. From my first interaction with it, I was particularly impressed by its exclusive recommendations and suggestions, making me feel valued as a user. In my opinion, the main difference between the two is that DeepSeek is ideal if you require an open-source AI with a focus on coding, enterprise AI, and real-time automation, while ChatGPT is best if you need a well-rounded conversational AI with strong natural language capabilities. Both tools provide valuable information, but they approach the same commands differently. In areas such as coding automation, technical research, and real-time AI applications, DeepSeek overtakes ChatGPT, delivering more specialized, efficient, and cost-effective solutions.
Here’s a detailed comparison to help you understand the key differences between DeepSeek vs ChatGPT, and when to choose one over the other.
What Is Deepseek?
DeepSeek, launched by Lian Wenfeng, is an open-source AI model based in Hangzhou, China, focusing on technical tasks such as coding automation, enterprise AI, and real-time AI applications. It has introduced powerful language models like DeepSeek LLM V2, V3, and R1, the latter being the latest, launched in January 2025. DeepSeek emphasizes cost-efficiency and enhanced reasoning capabilities, excelling in complex coding and mathematical tasks.
What Is ChatGPT?
Developed by OpenAI, ChatGPT is a widely used AI model designed for conversational AI, content generation, and assistance in coding. Since its release in November 2022, it has evolved into versions like GPT-4 and the latest, ChatGPT-01, which was launched in December 2024, designed to handle more complex reasoning tasks using a “Chain of Thought” technique.
Key Differences Between DeepSeek vs ChatGPT:
DeepSeek is optimized for coding, technical tasks, and real-time automation, with a focus on Chinese and English languages. It is open-source, allowing developers to modify it for specific applications.
ChatGPT is more general-purpose, excelling in creative writing, customer service, and natural language processing, with extensive support for multiple languages beyond just Chinese and English.

Deepseek vs ChatGPT 4: Performance Comparison
Coding and Mathematical Capabilities:
DeepSeek excels in coding and mathematical tasks, with its DeepSeek-Coder V2 model outperforming other models, , in benchmark tests. It specializes in coding automation, debugging, and optimization, making it the ideal choice for developers. You can download the DeepSeek-Coder V2 model to access its advanced coding capabilities for more efficient results.
ChatGPT provides code assistance but is not as specialized as DeepSeek in coding tasks. While it supports various programming languages, its focus is broader, encompassing both creative and technical aspects.
Multilingual Support:
One of the major differences when comparing DeepSeek V3 vs ChatGPT 4 is multilingual support.
DeepSeek focuses primarily on English and Chinese, with its models optimized for Chinese-language applications. Using an advanced Transformer architecture, DeepSeek delivers exceptional performance in these two languages. While its training data predominantly consists of English and Chinese content, DeepSeek can process additional languages. However, its proficiency beyond English and Chinese may be limited, with responses in languages like Japanese lacking full naturalness.
On the other hand, ChatGPT supports a wide range of languages, including English, Spanish, French, German, and more. OpenAI has consistently improved ChatGPT’s multilingual capabilities, expanding support for various languages and accents. Recent updates have enhanced the voice mode, allowing for more natural and fluid interactions across different languages.
While both chatbots offer multilingual functionalities, ChatGPT excels in supporting a broader range of languages, while DeepSeek demonstrates superior performance in English and Chinese.
Deployment Options:
DeepSeek offers a range of deployment options, including web access, API integration, and local deployment with various hardware and software configurations. ChatGPT provides web and API access but does not currently support local deployment.
DeepSeek Deployment Options:
Hardware Requirement
Full models require substantial hardware resources, such as GPUs with significant VRAM (e.g., Nvidia RTX 3090 or higher.
Software Tools for Local Deployment
ChatGPT Deployment Options:
Pricing and Accessibility
DeepSeek provides competitive pricing, with costs significantly lower than some competitors. For instance, the DeepSeek R1 model is priced at $0.55 per 1 million tokens for input and $2.19 per 1 million tokens for output. In contrast, OpenAI’s models are priced at $15 and $60 per 1 million tokens for input and output, respectively. This makes DeepSeek’s API approximately 96.4% cheaper than ChatGPT’s API.
