GateSight: Recurrent Memory Anticipates Attention Memory for Query-Agnostic KV Eviction in Hybrid LLMs
TL;DR
GateSight introduces a novel approach to managing key-value (KV) memory in hybrid language models by predicting the future utility of KV entries, significantly improving efficiency. It achieves high accuracy with a reduced KV cache, outperforming existing methods in various benchmarks.
✦ Why It Matters
Implement GateSight to enhance memory efficiency in your hybrid language models today.
Key Takeaways
- Utilize GateSight for efficient KV memory management.
- Reduce KV cache size while maintaining accuracy.
- Leverage multilayer perceptrons for predicting KV utility.
- Test performance improvements on SCBench and RULER-4096.
How It Works
GateSight predicts the future utility of KV entries by analyzing signals emitted from GDN layers during prefill. It uses lightweight multilayer perceptrons to assess which entries are most beneficial for attention layers, allowing for proactive memory management.
