Choosing between language models like DeepSeek and ChatGPT has become an important question for developers, researchers, and businesses in 2025. Both offer advanced capabilities, but their architectures, costs, and applications differ significantly. In this article, we explore these differences through a technical lens, highlighting key considerations for decision-making.
1. Architecture and Computational Efficiency
The foundation of any AI model lies in its architecture. DeepSeek, developed by a Chinese startup, uses a Mixture-of-Experts (MoE) architecture with 671 billion parameters, of which only 37B are activated per task. This enables dynamic specialization, reducing memory and energy consumption. Additionally, its training with mixed precision optimizes GPU usage, processing 14.8 trillion tokens at a cost 18 times lower than GPT-4o.
ChatGPT, based on GPT-4, is a dense model with 1.8 trillion parameters, designed for generalization. Its architecture prioritizes contextual coherence and conversational fluency, but demands significantly greater computational resources, with training in FP16.
Technical verdict:
- DeepSeek is ideal for specialized tasks (e.g., coding) with budget constraints.
- ChatGPT offers versatility for general use, but at a higher cost.
2. Performance on Specific Tasks
Coding and Mathematics
DeepSeek excels in technical scenarios. In benchmarks such as MATH 500 and Codeforces, it outperforms ChatGPT in precise code generation and complex mathematical problem-solving. A practical test with Node.js and isolated-vm showed that DeepSeek provided detailed solutions with IO constraints, while competing models failed to offer practical guidance.
Text Generation and NLP
ChatGPT maintains an advantage in creativity and narrative coherence. In article writing tests, although DeepSeek provides more concrete data, ChatGPT produces more structured texts that better adapt to vague instructions. Additionally, its support for 200 million context tokens (vs. 130k for DeepSeek) makes it superior for extended dialogues.
Case Study
To evaluate the performance of both tools, we conducted a series of standardized tests that included specific information retrieval and synthesis tasks. These tasks consisted of searching for data on the internet within a predetermined time window and then creating a concise, informative summary of the main news related to the requested topic.
A practical example was the prompt: "Summarize the main sports news published in August 2024." In this case, the tools needed to access up-to-date sources, identify the most relevant events (such as the Paris Olympics, football and basketball highlights, and controversies involving athletes) and organize the information in a clear, structured manner. This approach allowed us to compare not only the accuracy of responses but also the contextualization ability and the efficiency in delivering relevant content.
As a result of the comparative tests, we observed significant differences in approach and response style between the two tools. In the example provided, ChatGPT more strictly followed the instruction to produce a concise, direct summary, focusing on synthesizing information clearly and objectively. Its response was structured in well-defined topics, emphasizing the most relevant events succinctly, such as the main achievements at the Paris Olympics and some focus on Brazilian athletes.
On the other hand, DeepSeek presented a more comprehensive and detailed response, going beyond a simple summary. It included additional context, such as analyses of the impact of sporting events, technical data on broken records, and even information about the infrastructure and sustainability of the Olympics.

Summary of Major Sports News from August 2024 August 2024 was marked by high-impact sporting events, headlined by the Paris Olympic Games, along with international competitions across various disciplines. Here are the highlights:
1. Paris Olympics: Historic Achievements and Controversies Simone Biles solidifies her legacy: The American gymnast, widely regarded as the greatest of all time, won two gold medals (team and individual), reaffirming her supremacy after her withdrawal in Tokyo 2020. Her journey was highlighted as a symbol of mental resilience. Leon Marchand shines in swimming: The 22-year-old Frenchman won four gold medals, becoming a national legend. His victories were celebrated with chants from fans in packed pools. Innovative opening ceremony: For the first time, the opening ceremony took place on the Seine River, with delegations parading on boats and a controversial show featuring the "Blue Man" (Philippe Katerine), criticized by religious groups for allusions to Christian iconography. New sports and records: Breakdancing debuted as an Olympic sport, with Canadian Phil Wizard winning gold. China dominated table tennis and diving, claiming all eight available gold medals. Controversies: Algerian boxer Imane Khelif faced questions about her gender eligibility after winning a bout in 46 seconds. Additionally, Chinese swimmers were involved in doping allegations, sparking debates about transparency in investigations.
2. Basketball and Football: Gold for the USA Men's basketball: The US team, featuring stars like LeBron James and Steph Curry, defeated France (98-87) in the final, securing their fifth consecutive gold. Curry was decisive with three three-pointers in the final minutes. Women's football: The Americans beat Brazil (1-0) in the final, with a goal from Mallory Swanson. Goalkeeper Alyssa Naeher was instrumental, while Marta retired without an Olympic gold.

3. Cost and Accessibility
- DeepSeek: With a training cost of US$5.5 million (vs. US$100 million for ChatGPT), it is a budget-friendly option. Its open-source code allows customization, attracting developers seeking integration into specific systems.
- ChatGPT: Offers a limited free plan, but premium features (e.g., ChatGPT Plus) cost US$20/month. Its plug-and-play infrastructure facilitates rapid adoption, though with less flexibility for technical adjustments.
4. Transparency and Ethical Considerations
- DeepSeek: Its open-source nature promises transparency, but has raised controversies. Reports indicate that the DeepSeek-V3 model occasionally identifies itself as "ChatGPT," possibly due to training on GPT-4-derived data. This raises concerns about violation of OpenAI's terms of service and propagation of hallucinations.
- ChatGPT: Follows strict ethics and privacy guidelines, even allowing users to disable conversation history. However, its closed-source code limits independent audits.
