The rise of DeepSeek in China introduces a strong alternative to ChatGPT, challenging OpenAI with its cost-efficient and open-source model. This new AI assistant is gaining attention for its significant capabilities, particularly in mathematical domains, making it a great option for students handling homework, projects, and coding tasks. In contrast, ChatGPT remains the more versatile choice, excelling in writing, creative ideas, and daily conversations. Both models have unique strengths, but their performance, cost, and accuracy vary depending on the use case. Users must compare the features, explore distinct ways they tackle problems, and consider which AI tool best suits their needs in real-world scenarios. Whether for problem-solving, research, or learning, each has a position in the growing AI landscape, shaping the future of natural language processing.

Features Comparison Between DeepSeek and ChatGPT
Writing Assistance
ChatGPT and DeepSeek both excel in content creation but serve different needs. DeepSeek is ideal for technical writing, offering precise, formal documentation with technical specifications, while ChatGPT is more engaging, conversational, and great at explaining complex data concepts to non-technical stakeholders with rich context. For creating outlines, drafts, articles, blogs, and stories, both generate structured content. A Prompt Example, “Write a blog post on the advantages of eating healthy,” shows their differences—DeepSeek provides a logical flow, list, and bullet points, while ChatGPT adds contextual, detailed insights with self-insertions and rolls. In ranking the best history of players, DeepSeek responded in seconds with a top list, including summarised position, clubs, and achievements, featuring non-Scottish players like Rangers legend Brian Laudrup (Danish) and Celtic hero Henrik Larsson (Swedish) for their impact. ChatGPT ranked names like King Kenny at the top, offering a detailed, briefly, and accurately written response, showing how the game has changed over decades, yet the impact of these greats remains timeless. This fun test proved DeepSeek a comparable competitor in AI.
Coding and Technical Queries
For coders, DeepSeek offers efficient code generation, a modular approach for building, writing, and debugging, while ChatGPT excels in assistance, explanations, and guidance. Many developers use both AI models for coding challenges, from generating a WordPress plugin with PHP, JavaScript, and CSS to refining a snippet in a theme or adjusting the position on the web. The difference is clear—DeepSeek is cheaper, while ChatGPT ensures correctness with a plugin-free experience. During a ChatGPT outage, posts on X showed user reliance. AI researchers from Samsung Medical Center in Seoul, South Korea, tested their capabilities, pushing them to the limit with complex problems. On LinkedIn, experts like Chrome Developer Experience head at Google have echoed that DeepSeek and Anthropic’s Claude Sonnet, a hybrid model Amazon has invested in, are strong alternatives to OpenAI’s o1 for engineers.
A Unique Look at Their Capabilities
Both ChatGPT and DeepSeek have distinct strengths in handling data-driven projects. ChatGPT excels at generating diverse possibilities in seconds, while DeepSeek follows a single, well-developed approach, diving deep into detail. This makes ChatGPT ideal for quick brainstorming, while DeepSeek provides structured solutions with a refined strategy.
For a story about a boy on the moon, ChatGPT quickly responded with multiple summarised ideas, including one where Oliver follows the sounds of an orchestra of aliens. DeepSeek, however, delivered a longer response, which comprised a detailed journey of a curious character. While ChatGPT helps flourish early-stage concepts, DeepSeek is more useful for depth and refinement, making it an impressive choice for focused work.
Learning and Research
AI chatbots handle learning and researching differently. My history teacher once explained the First World War, where a complex situation among European powers led to conflict, sparked by the assassination of Archduke Franz Ferdinand in 1914. When tested, ChatGPT used a tutorial-style approach, breaking down complex topics into digestible explanations, making it great for understanding concepts in depth. DeepSeek, however, prioritizes precision, conciseness, and quick reference, making it ideal for fact-checking and data projects that require technical accuracy. While ChatGPT provides a detailed account with key factors, events, and a synopsis, DeepSeek offers a brief overview for clarity. Even Google’s Gemini assistant pulls from reputable sources like the Imperial War Museum in the UK, yet DeepSeek competes well with US competitors, proving useful for different methodologies and researching needs.
Differences Between DeepSeek and ChatGPT
DeepSeek-R1 uses Mixture-of-Experts (MoE) for resource-efficient processing, while ChatGPT 40 relies on a transformer-based approach with distinct strengths and weaknesses.
Model Architecture
DeepSeek uses a Mixture-of-Experts (MoE), activating a subset of its 671 billion parameters per request for better efficiency and performance. ChatGPT, with its traditional transformer, ensures consistency but is less resource-efficient.
Performance Strengths
DeepSeek excels in technical tasks, especially mathematics, with a 90% accuracy rate, making it valuable for working on complex problems. ChatGPT is stronger in understanding context, offering nuanced responses across a broader range of topics, using human-like reasoning and chain-of-thought problem-solving with minimal reliance on supervised datasets.
Customization and Ease of Use
DeepSeek offers extensive customization options but has a steeper learning curve and requires technical expertise. In contrast, ChatGPT prioritizes user-friendliness, providing a polished experience that is more accessible. While DeepSeek follows a monolithic 1.8 trillion-parameter design, ChatGPT is optimized for versatility, language generation, and creative tasks.
Accessibility and Cost
DeepSeek is open-source, freely available, and customizable by the community. ChatGPT follows a freemium model, with basic features free, but a subscription is needed for advanced capabilities. DeepSeek was trained in 55 days on 2,048 Nvidia H800 GPUs at a cost of $5.5 million, just 1/10th of ChatGPT’s expenses.
Pros and Cons of DeepSeek & ChatGPT
