Moving the Mean Toward the Known Good, Not Beyond It: What Inference-Time Interventions and Weight Consolidation Buy in Open-Ended Generation
AI InsightThe study shows that training on value-filtered self-generated data shifts the mean of open-ended generation toward known good values (excess reduced by 1.7-3.1 points) but does not surpass classic heuristics; three replications confirm consistent means (-2.0, -1.8, -1.9). This implies a ceiling for self-improvement, with gains from reducing poor outputs rather than exceeding limits.Key TakeawayCompared with prior emphasis on self-improvement surpassing limits, this experiment shows convergence toward a known good mean.Why It MattersQuantifies self-training gains as mean improvement not extreme breakthrough, providing evidence for expectations in generative self-improvement.Who's Affected- AI ResearchersCalibrates expectations of self-improvement ceiling, focusing on mean rather than extreme evaluations.
