Meta AI researchers, in collaboration with Stanford University, have introduced Mixture-of-Transformers (MoT), a novel sparse multi-modal transformer architecture designed to significantly reduce pretraining computational costs. MoT incorporates modality-specific parameters, optimizing text, image, and speech processing without the need for additional model components. This method has demonstrated remarkable improvements in efficiency, reducing computational resources by up to 55.8% while maintaining performance across multiple tasks, and achieving notable reductions in pretraining and training times.
