TeaCache4CogVideoX1.5

TeaCache can speedup CogVideoX1.5 1.8x without much visual quality degradation, in a training-free manner. The following video shows the results generated by TeaCache-CogVideoX1.5 with various rel_l1_thresh values: 0 (original), 0.1 (1.3x speedup), 0.2 (1.8x speedup), and 0.3(2.1x speedup).Additionally, the image-to-video (i2v) results are also demonstrated, with the following speedups: 0.1 (1.5x speedup), 0.2 (2.2x speedup), and 0.3 (2.7x speedup).

Usage

You can modify the rel_l1_thresh to obtain your desired trade-off between latency and visul quality, and change the ckpts_path, prompt, image_path to customize your identity-preserving video.

For T2V inference, you can use the following command:

cd TeaCache4CogVideoX1.5

python3 teacache_sample_video.py \
    --rel_l1_thresh 0.2 \
    --ckpts_path THUDM/CogVideoX1.5-5B \
    --prompt "A clear, turquoise river flows through a rocky canyon, cascading over a small waterfall and forming a pool of water at the bottom. The river is the main focus of the scene, with its clear water reflecting the surrounding trees and rocks. The canyon walls are steep and rocky, with some vegetation growing on them. The trees are mostly pine trees, with their green needles contrasting with the brown and gray rocks. The overall tone of the scene is one of peace and tranquility." \
    --seed 42 \
    --num_inference_steps 50 \
    --output_path ./teacache_results

For I2V inference, you can use the following command:

cd TeaCache4CogVideoX1.5

python3 teacache_sample_video.py \
    --rel_l1_thresh 0.1 \
    --ckpts_path THUDM/CogVideoX1.5-5B-I2V \
    --prompt "A girl gazed at the camera and smiled, her hair drifting in the wind." \
    --seed 42 \
    --num_inference_steps 50 \
    --output_path ./teacache_results \
    --image_path ./image/path \
