ProSparse: Introducing and Enhancing Intrinsic Activation Sparsity within Large Language Models

COLING 2025main

Activation sparsity refers to the existence of considerable weakly-contributed elements among activation outputs, serving as a promising paradigm for accelerating model inference. Nevertheless, most large language models (LLMs) adopt activation functions without intrinsic activation sparsity (e.g.,…

SpaceServe: Spatial Multiplexing of Complementary Encoders and Decoders for Multimodal LLMs

NeurIPS 2025poster

Recent multimodal large language models (MLLMs) marry modality-specific vision or audio encoders with a shared text decoder. While the encoder is compute- intensive but memory-light, the decoder is the opposite, yet state-of-the-art serving stacks still time-multiplex these complementary kernels, id…
