Technical Principles and Performance of TeaCache
TeaCache is MultiTalk's dynamic cache optimization system designed for low memory devices. Its core technology is:
- Parameter reuse: Intelligent caching of middle layer parameters by analyzing the structural properties of DIT (Diffusion Transformer) models
- Dynamic offloading: LRU algorithm is used to manage the video memory, temporarily dumping inactive parameters to host memory.
- Quantization compression: 8-bit quantization of feature maps to reduce 40% memory usage with less than 2% quality loss
Actual test data shows that on a RTX 3060 device with 12GB of video memory:
- 2.3x faster video generation with TeaCache enabled
- Supports up to 30 seconds long video generation at 720p resolution
- With the num_persistent_param_in_dit=0 parameter, the minimum video memory requirement can be reduced to 8GB.
