币界网报道：The European Central Bank (ECB) has leveraged OpenAI's ChatGPT to enhance the accuracy of its GDP growth forecasts, according to a recent study. Researchers found that AI-assisted predictions outperformed traditional models, particularly during economic shocks like the COVID-19 pandemic. The ECB team fine-tuned ChatGPT-4 by providing historical GDP data and asking for projections, which yielded results 30% more accurate than conventional methods. The AI excelled in interpreting complex, real-time data such as news reports and social media, offering quicker adjustments to forecasts. However, the study noted limitations, including ChatGPT's tendency to "hallucinate" incorrect figures when data was scarce. The ECB emphasized that AI should complement, not replace, human analysts, as economic forecasting requires nuanced judgment beyond raw data processing. This experiment marks a significant step in central banks' exploration of AI tools for macroeconomic analysis.
