System Efficiency
SparseBalance significantly improves system efficiency by addressing sequence length and sparsity heterogeneity. Its dynamic sparsity tuning (DST) rebalances workload at the layer level, reducing attention budget for bottlenecks and increasing it for non-bottlenecks to exploit pipeline bubbles. Sparsity-aware batching (SAB) provides coarse-grained initial balance.

Model Accuracy
SparseBalance maintains or improves model accuracy. The bidirectional sparsity adjustment in DST, guided by an anchor-guided thresholding mechanism, ensures critical information is preserved. Experimental results show stable training loss and improved long-context capability on benchmarks like LongBench, particularly for QA tasks.
