Comparison of ChatGPT (with Web Search) and DeepSeek for Document Processing and Advising Under Uncertain Situations
1. Document Processing
ChatGPT with web search enabled has strong natural language understanding and can process complex documents, including legal, financial, and technical materials. It can summarize, analyze, and extract key insights from PDFs, Word documents, and other text formats. Additionally, it can generate structured outputs like executive summaries, risk assessments, or compliance reports.
DeepSeek also supports document analysis but is more optimized for retrieving information from web-based sources. It is effective in summarizing technical documents and research papers, particularly in Chinese-language content. However, its ability to deeply interpret legal and financial documents may not be as refined as ChatGPT’s.
2. Advising Under Uncertainty
ChatGPT with web search combines historical data with real-time updates, making it well-suited for forecasting trends, assessing risks, and advising on complex decisions. It can generate structured responses such as scenario analyses, decision trees, and Monte Carlo simulations. This makes it valuable for business strategy, crisis management, and policy analysis.
DeepSeek, with its web integration, excels in tracking fast-changing topics, such as government policies, financial regulations, and geopolitical shifts. It is particularly effective in retrieving and synthesizing the latest news, but its ability to provide structured, in-depth analysis on uncertain situations may be more limited compared to ChatGPT.
3. Web Search Capability
Both ChatGPT (with browsing enabled) and DeepSeek integrate web search, allowing them to pull real-time data. ChatGPT, however, processes this information with more advanced reasoning, ensuring that insights are contextualized rather than just retrieved. This makes it more reliable for in-depth advising.
DeepSeek, on the other hand, prioritizes real-time retrieval, making it faster at delivering breaking news, government policy updates, and recent market trends. It is particularly strong in web-based research, though it may require additional validation for decision-making in uncertain scenarios.
4. Quantitative Analysis
ChatGPT is highly capable of assisting with numerical modeling, forecasting, and risk assessment. It can generate and debug Python or R scripts, helping with statistical analysis, econometrics, and financial modeling. This makes it more suitable for advising in data-driven uncertainty, such as market forecasting or macroeconomic analysis.
DeepSeek has a more retrieval-based approach, meaning it is better at finding external datasets rather than performing deep quantitative computations. While it can assist with data discovery, its ability to directly generate structured financial models or simulations is more limited.
5. Legal and Policy Analysis
ChatGPT is strong in legal and policy reasoning, capable of analyzing contracts, summarizing regulatory changes, and evaluating policy implications. It can generate structured legal arguments and compliance strategies based on both historical precedents and real-time updates.
DeepSeek is useful for retrieving the latest legal and policy developments, particularly in regulatory environments like China’s. However, its depth of legal reasoning may not be as advanced as ChatGPT’s when handling complex legal interpretations.
6. Scientific and Technical Document Processing
Both ChatGPT and DeepSeek can summarize academic papers, patents, and technical documents. ChatGPT provides deeper contextualization and structured analysis, including the ability to generate LaTeX for mathematical content. DeepSeek is strong in retrieving recent research papers and technical documentation but may not provide as structured a breakdown as ChatGPT.
7. Business and Financial Uncertainty Analysis
ChatGPT is more effective for structured economic and financial forecasting. It can generate risk assessments, perform market scenario planning, and assist in financial strategy formulation. It is particularly useful for long-term economic trend forecasting and structured business advising.
DeepSeek is better suited for tracking real-time financial updates, such as stock movements, central bank decisions, and corporate developments. While it is useful for short-term insights, its ability to structure long-term financial forecasts is more limited compared to ChatGPT.
8. Multilingual Capabilities
ChatGPT has strong multilingual support, making it effective for cross-border policy and market research. It performs well in both English and Chinese, as well as many other languages.
DeepSeek is particularly strong in Chinese-language processing, making it ideal for analyzing China-focused research, government policies, and financial reports. It may have an advantage in retrieving China-specific data but could be less effective in broader multilingual research compared to ChatGPT.
Conclusion
ChatGPT with web search enabled is the better choice for deep analysis, structured advising, and document-heavy workflows. It is particularly strong in quantitative analysis, legal reasoning, and long-term forecasting.
DeepSeek is more effective for real-time policy and financial tracking, especially in China-related topics. It is useful for retrieving the latest news but may require additional interpretation for structured decision-making.
