Overview

• SRT (Self-Calibration with Repeated Trials) improves large language model outputs
• Works by using model's own confidence to decide when to do more sampling
• Achieves 90% of full sampling performance with just 30% of compute
• Compatible with existing decoding methods like best-of-N
• Maintains accuracy while reducing computational costs
• No fine-tuning required; works at inference time

Plain English Explanation

Language models like ChatGPT generate varying answers when asked the same question multiple times. Sometimes they're right, sometimes they're wrong. This inconsistency creates a challenge: how do we get the best answer without wasting resources?
