TeaCache4LuminaT2X

TeaCache can speedup Lumina-Image-2.0 2x without much visual quality degradation, in a training-free manner. The following image shows the results generated by TeaCache-Lumina-Image-2.0 with various rel_l1_thresh values: 0 (original), 0.1 (1.05x speedup), 0.2 (1.15x speedup), 0.3 (1.25x speedup).

📈 Inference Latency Comparisons on a 4070 laptop(size 1024 x 1536)

Lumina-Image-2.0	TeaCache (0.1)	TeaCache (0.2)	TeaCache (0.3)
~97.74s	~93.19s	~84.72s	~78.43s

Installation

pip install --upgrade diffusers[torch] transformers protobuf tokenizers sentencepiece
pip install flash-attn --no-build-isolation

Usage

You can modify the thresh in line 113 to obtain your desired trade-off between latency and visul quality. For single-gpu inference, you can use the following command:

python teacache_lumina2.py
