UnverifiedRecall quality affects the final output more than model size; index granularity, update timing, and fragment ordering all directly change the usability of the generated results.80% similarVerifiedThere is a fundamental trade-off between low-cost data collection and data quality; cheap but excessively noisy data may actually harm final model performance.79% similarUnverifiedIgnoring error correlation causes the combined variance to be underestimated, and the underestimation factor grows with group size; this factor accurately predicts the degree of coverage failure.78% similarUnverifiedUnder VRAM-constrained conditions, the model quantization level has a greater impact on performance than the KV cache quantization level.77% similar
