GPT-5.4 vs GPT-4.1 Mini for Data Analysis

Which AI model is better for data analysis? We compare GPT-5.4 and GPT-4.1 Mini on the criteria that matter most - with a clear verdict.

Why your data analysis LLM choice matters

Data analysis LLMs must reason correctly about numbers, generate accurate and executable code, and translate raw data into clear, actionable narrative. Unlike writing errors that are easy to spot, quantitative mistakes can go undetected - making model reliability and confidence calibration especially critical for data workflows.
