HARD-KV framework boosts LLM inference speed by 2x

Researchers have developed HARD-KV, a novel framework designed to optimize long-context Large Language Model (LLM) inference. This system addresses the conflict between head-adaptive compression algorithms, which offer accuracy through dynamic memory budgets, and modern inference engines like vLLM that require static memory patterns for efficiency. HARD-KV introduces a Cascade Cache hierarchy and a Logits Calibration mechanism to unify importance metrics and enable consistent budgeting across different model heads. Experiments show HARD-KV can improve throughput by up to two times while maintaining high-fidelity generation for contexts exceeding 10,000 tokens. AI

IMPACT Improves LLM inference efficiency, potentially enabling faster and more capable long-context applications.

    HARD-KV: Head-Adaptive Regularization for Decoding-time KV Compression

    arXiv:2606.28831v1 Announce Type: cross Abstract: Long-context LLM inference faces a fundamental conflict: head-adaptive compression algorithms (e.g., Top-$p$ nucleus sampling) offer superior accuracy by dynamically fluctuating memory budgets, yet modern inference engines (e.g., …
