RIFT improves KV cache compression for speculative decoding in LLMs

Researchers have introduced RIFT, a novel KV cache compression strategy designed to improve the efficiency of speculative decoding in large language models. RIFT addresses the issue of "decode staleness" where compression methods lose relevance over long output generations. By balancing prefill information with recently generated tokens and employing an adaptive refresh strategy, RIFT enhances draft model quality while managing decode latency. This approach, combined with compressibility-driven training, allows the Qwen3.5-4B model to draft for Qwen3.5-122B while retaining over 98% of its full-cache acceptance length on substantial inputs and outputs. AI

IMPACT Enhances efficiency and cost-effectiveness for long-context generation in large language models.
