[TeaCache](https://github.com/LiewFeng/TeaCache) can speedup [Lumina-Image-2.0](https://github.com/Alpha-VLLM/Lumina-Image-2.0) without much visual quality degradation, in a training-free manner. The following image shows the experimental results of Lumina-Image-2.0 and TeaCache with different versions: Lumina-Image-2.0 (~25 s), TeaCache (0.2) (~16.7 s, 1.5x speedup), TeaCache (0.3) (~15.6 s, 1.6x speedup), TeaCache (0.5) (~13.79 s, 1.8x speedup), TeaCache (1.1) (~11.9 s, 2.1x speedup).
