The work addresses compute and memory bottlenecks that limit autoregressive large language models (LLMs) and standard masked diffusion models.", "body_md": "arXiv:2607.24841v1 Announce Type: new\nAbstract: Autoregressive (AR) large language models (LLMs) are inherently inefficient at inference time because each generated token requires accessing the full set of model parameters, leading to low operational intensity and high energy consumption. Masked diffusion language models (MDLMs) partially address this limitation for memory-bound settings by allowing multiple tokens to be generated per parameter access. In order to further enhance inference efficiency on modern platforms with extensive in-chip memory, this work proposes neuromorphic MDLMs (N-MDLMs), which integrate block diffusion with spike-based neuromorphic computation to jointly improve throughput and energy efficiency. While block diffusion increases token throughput by producing multiple tokens per parameter access, spike-induced sparsity reduces effective parameter traffic and computations by skipping inactive channels. To analyze the synergistic effect of sparsity and diffusion, we develop a token-level roofline-inspired model that captures the combined impact of block-parallel generation and spike sparsity on decoding efficiency. Experimental results on translation tasks show that, thanks to spike-induced sparsity, N-MDLMs achieve substantial improvements in energy efficiency and throughput even in compute-bound platforms for which MDLMs would fail to improve over AR-LLMs.", "url": "https://wpnews.pro/news/neuromorphic-diffusion-language-models-addressing-compute-and-memory-bottlenecks", "canonical_source": "https://arxiv.org/abs/2607.24841", "published_at": "2026-07-29 04:00:00+00:00", "updated_at": "2026-07-29 04:26:16.462639+00:00", "lang": "en", "topics": ["artificial-intelligence", "large-language-models", "neural-networks", "ai-research"], "entities": ["arXiv"], "alternates": {"html": "https://wpnews.pro/news/neuromorphic-diffusion-language-models-addressing-compute-and-memory-bottlenecks", "markdown": "https://wpnews.pro/news/neuromorphic-diffusion-language-models-addressing-compute-and-memory-bottlenecks.md", "text": "https://wpnews.pro/news/neuromorphic-diffusion-language-models-addressing-compute-and-memory-bottlenecks.txt", "jsonld": "https://wpnews.pro/news/neuromorphic-diffusion-language-models-addressing-compute-and-memory-bottlenecks.jsonld"}}
