ARKV: Adaptive and Resource-Efficient KV Cache Management under Limited Memory Budget for Long-Context Inference in LLMs
🤖AI Summary
Researchers propose ARKV, a new framework for managing memory in large language models that reduces KV cache memory usage by 4x while preserving 97% of baseline accuracy. The adaptive system dynamically allocates precision levels to cached tokens based on attention patterns, enabling more efficient long-context inference without requiring model retraining.
Key Takeaways
- →ARKV reduces KV cache memory usage by 4x while maintaining ~97% of baseline accuracy on long-context benchmarks
- →The framework uses adaptive precision allocation based on per-layer attention dynamics and token importance scoring
- →System works without requiring model retraining or architectural modifications to existing LLMs
- →Experiments on LLaMA3 and Qwen3 models show minimal throughput loss compared to full-precision baselines
- →ARKV significantly outperforms uniform quantization approaches on mathematical reasoning tasks like GSM8K
