Two new research papers introduce novel methods for improving the efficiency and structure-awareness of autoregressive decoding in large language models, particularly for handling long contexts and graph-based data. CommunityKV formulates sparse attention as a community detection problem on token graphs, achieving up to 1.71x higher generation throughput than dense attention on Qwen3 and Llama-3.1 models. GraphVQ addresses the challenge of representing graphs as discrete tokens by using a VQ-VAE to quantize node contexts and a structure-aware decoder that conditions on pair features, improving graph generation fidelity and outperforming other methods on several datasets.
