New Autonomy-of-Heads method boosts LLM efficiency without data

Researchers have developed a novel data-free method called Autonomy-of-Heads (AoH) to improve the efficiency of long-context Large Language Models. AoH identifies retrieval and streaming heads by analyzing the spectral geometry of query-key projections, a process that is independent of runtime attention scores. This approach allows for significant reductions in prefill and decode latency, by up to 66.0% and 41.4% respectively, while also cutting KV-cache memory by 50.0% at 256K tokens, all while retaining 96.5% of Full Attention performance at 50% sparsity.

    Autonomy-of-Heads: Data-Free Sparse Attention from Frozen Query-Key Geometry

    arXiv:2608.06849v1 Announce Type: cross Abstract: Long-context LLM inference is bottlenecked by quadratic attention computation and growing KV-cache costs. Existing sparse attention and KV-compression methods typically decide which tokens or heads to preserve from runtime attenti…
