Researchers have developed a method to optimize the placement of large lookup tables for LLMs like DeepSeek-V4.1 by utilizing per-layer prefetch deadlines. This approach allows for tables to be stored on slower storage like NVMe or even remote memory, significantly reducing host memory requirements without a substantial performance penalty. The study demonstrates that by intelligently managing read times and leveraging techniques like session reuse, memory usage can be drastically cut, freeing up resources for other critical functions like KV caching, which in turn boosts throughput and reduces latency.
