TeaCache can speedup Lumina-T2X 2x without much visual quality degradation, in a training-free manner. The following image shows the results generated by TeaCache-Lumina-Next with various rel_l1_thresh values: 0 (original), 0.2 (1.5x speedup), 0.3 (1.9x speedup), 0.4 (2.4x speedup), and 0.5 (2.8x speedup).
