A new study on arXiv investigates the gap between simulated and real-world developer behavior for proactive coding assistants. Researchers collected data from 1,246 industry developers using a custom Visual Studio Code extension over three days. Their findings indicate that simulated traces do not accurately reflect real development patterns, potentially overestimating the performance of current AI assistants. The study also introduces ProCodeBench, a benchmark based on real-world data, and suggests that while simulated data can complement real data, it cannot replace it for training and evaluation. AI
