NEW YORK, NEW YORK, UNITED STATES, July 1, 2025 -- A new research report from Marketscience provides the first comprehensive comparison of how leading generative AI models perform on practical marketing data challenges as organizations struggle with increasingly fragmented data across CRMs, social platforms, and analytics tools.
The report "Streamlining Marketing Data Management with Generative AI” benchmarks how large language models (LLMs) like ChatGPT, Claude, and DeepSeek are able to automate core marketing data tasks like data cleaning, transformation, and integration – and identifies where AI can deliver efficiency gains and where human oversight remains essential.
“Many businesses know their data is underused, but they don’t know where to begin,” said Sebastian Shapiro, Partner at Marketscience. “This research helps executives see how AI tools actually perform on the work marketers do every day.”
Key Reseach Findings
Marketscience tested ChatGPT, Claude, and DeepSeek across four common use cases:
- Data Processing & Cleaning
- Cross-Table Data Recognition
- Time Series Analysis
- Code Generation for ETL Pipelines
Claude consistently delivered the strongest results, offering well-documented code, error handling, and useful clarifications before executing complex tasks. ChatGPT was accurate and intuitive but sometimes made assumptions without flagging ambiguous inputs. DeepSeek struggled with consistency and depth, underperforming on interpretability and reuse.
Strategic Implications for Marketing Leaders
The guide emphasizes that while generative AI can dramatically reduce manual effort, it’s not a silver bullet. Models often require detailed instructions, and logical reasoning can still fall short—especially in ambiguous scenarios. Human oversight is still essential in many workflows.
