Model Architecture: The Brain Behind the AI
The architecture of an AI model determines how it processes information and generates responses. ChatGPT and DeepSeek take different approaches in this regard:
ChatGPT: The Power of a Dense Model
ChatGPT, based on OpenAI’s GPT-4, follows a dense model approach. This means that every time it generates a response, it utilizes all its parameters, resulting in highly coherent and well-structured outputs.
The GPT-4 architecture boasts around 1.8 trillion parameters, making it one of the largest AI models to date.
DeepSeek: A Smarter Mixture-of-Experts (MoE) Model
DeepSeek, on the other hand, employs a Mixture-of-Experts (MoE) architecture. This model consists of 671 billion parameters, but only 37 billion are actively used during any given query.
MoE models divide tasks among different “expert” networks, making DeepSeek more efficient and cost-effective compared to dense models like ChatGPT.
👉 Key Takeaway: ChatGPT relies on sheer power for performance, while DeepSeek uses a more selective approach to optimize efficiency.
Training and Computational Costs
AI models require enormous computational resources to train, and the costs can vary dramatically. Let’s compare how ChatGPT and DeepSeek differ in this aspect.
ChatGPT: Expensive and Resource-Intensive
ChatGPT was trained using around 8,000 Nvidia H100 GPUs, with an estimated cost of over $100 million. This makes it one of the most resource-hungry AI models in the industry.
The dense model structure requires massive hardware and electricity, making it costly for both OpenAI and users who pay for premium access.
DeepSeek: A Budget-Friendly Competitor
DeepSeek, in contrast, was trained using only 2,048 Nvidia H800 GPUs, with a total cost of approximately $5.5 million. This lower training cost is due to its MoE architecture, which reduces the need for extensive computational power.
👉 Key Takeaway: ChatGPT demands more computing power and costs significantly more to train, while DeepSeek achieves competitive performance at a fraction of the cost.
ChatGPT vs. DeepSeek: Performance and Capabilities
The ultimate test of an AI model is how well it performs across various tasks. ChatGPT and DeepSeek excel in different areas, depending on their architectural design.
ChatGPT: Superior in General Language Tasks
ChatGPT is widely recognized for its creative writing, conversational abilities, and general knowledge. It can generate well-structured responses, making it an ideal choice for customer service, blogging, and content creation.
DeepSeek: A Stronger Choice for Math and Coding
DeepSeek outperforms ChatGPT in structured reasoning tasks, math, and coding. For example, in AIME 2024 (Advanced Math Problem-Solving), DeepSeek scored 79.8, while ChatGPT scored just 9.3. In coding challenges on Codeforces, DeepSeek achieved a rating of 2,029, compared to ChatGPT’s 759.
👉 Key Takeaway: ChatGPT is more versatile for general use, while DeepSeek excels in technical and structured problem-solving.

AI Philosophy: Research vs. Commercialization
The motivations behind the development of ChatGPT and DeepSeek reveal stark differences in corporate philosophy and long-term goals.
OpenAI: A Business-First Model
OpenAI, the company behind ChatGPT, has adopted a commercial approach, focusing on profitability, premium subscriptions, and enterprise solutions. It relies heavily on investment funding and aims to scale AI for widespread business applications.
DeepSeek: Research-Driven Innovation
DeepSeek, led by Liang Wenfeng, prioritizes AI research and technological advancements over immediate commercial gain. The company focuses on building models that advance AI knowledge rather than pushing for mass-market adoption.
👉 Key Takeaway: OpenAI is driven by monetization, while DeepSeek is more focused on long-term AI research.
ChatGPT vs. DeepSeek: Market Impact and Competition
The rise of DeepSeek has shaken up the AI industry, forcing competitors to rethink their strategies.
DeepSeek’s Disruption
DeepSeek’s cost-effective model has led to shifts in AI hardware stock prices and caused concern among established players. Companies that invested heavily in GPUs and expensive AI models now face competition from a more affordable yet powerful alternative.
Response from Other AI Players
Following DeepSeek’s launch, other tech giants like Baidu announced their own cost-effective AI models. Baidu’s Ernie X1 was introduced as a cheaper alternative to DeepSeek, offering similar capabilities at an even lower cost.
👉 Key Takeaway: DeepSeek has disrupted the AI market, leading to a race for cheaper, smarter AI solutions.
Content Moderation and Ethical Considerations
AI models must balance openness and ethical responsibility, but different companies have different approaches to moderation.
ChatGPT: Moderation with Some Flexibility
ChatGPT follows OpenAI’s content moderation policies, designed to prevent misinformation, bias, and inappropriate content. However, it allows discussions on most global topics within reasonable guidelines.
DeepSeek: Stricter Controls, Especially on Sensitive Topics
DeepSeek operates under China’s AI regulations, meaning it avoids politically sensitive topics like Taiwan or censorship issues. While this ensures compliance with local laws, it may limit the model’s usability in certain discussions.
👉 Key Takeaway: ChatGPT offers broader topic coverage, while DeepSeek follows stricter content regulations based on regional policies.
Future Developments: What’s Next?
Both OpenAI and DeepSeek have ambitious plans for their AI models, setting the stage for future advancements.
OpenAI’s Roadmap
OpenAI continues to enhance ChatGPT’s capabilities, with improvements in reasoning, multimodal understanding, and contextual awareness. The company is also developing new models to expand AI applications in business and productivity tools.
DeepSeek’s Vision for AGI
DeepSeek aims to push AI beyond its current limitations, with plans for DeepSeek R2 and V4. These versions will further enhance reasoning, problem-solving, and efficiency, potentially moving closer to Artificial General Intelligence (AGI).
👉 Key Takeaway: OpenAI is expanding ChatGPT’s business applications, while DeepSeek is pushing AI research toward AGI.
