Solving LLM Repetition Problem in Production: A Comprehensive Study of Multiple Solutions

Researchers from Shenzhen Sunline Tech Co., Ltd. addressed the LLM repetition problem in production financial batch code interpretation by evaluating multiple solutions. Their study found that Beam Search with `early_stopping=True` effectively eliminated repetition, achieving a 0% repetition rate, and that Direct Preference Optimization (DPO) reduced repetition rates from 13-60% to 0-2% across various scenarios, restoring normal processing performance.
