Reduced Inference Costs

The proposed Attention-State Memory (ASM) eliminates the need for repeated attention computation over long prefixes during inference. This results in significant reductions in latency, scaling logarithmically with memory size rather than linearly with prefix length. For enterprises, this translates directly to lower operational costs for LLM applications and faster response times, especially in high-throughput scenarios.

By leveraging precomputed attention states and a lookup-based memory, ASM decouples the memory footprint from inference latency, allowing for more efficient scaling of long-context applications without proportional increases in compute resources.

Enhanced Performance in ICL & RAG

ASM demonstrates superior or comparable accuracy to full-attention models across various benchmarks, including In-Context Learning (ICL) and Retrieval-Augmented Generation (RAG). Specifically, it outperforms ICL at 1K-8K memory budgets and surpasses full-attention RAG performance with only 20% of the memory footprint on the NBA benchmark.

This is achieved by externalizing prefix knowledge into a compact, reusable memory. Unlike methods that suffer from prefix decay, ASM ensures the influence of the prefix remains stable as generation proceeds, leading to more consistent and reliable LLM outputs for complex enterprise tasks like document summarization, code generation, and advanced chatbots.

Training-Free & Scalable Solution

A key innovation of ASM is its training-free construction. The memory is built entirely through forward-only computation, avoiding the resource-intensive and time-consuming gradient-based training required by other internalization approaches. This makes ASM highly adaptable to dynamic prefix updates and new contexts, a critical feature for agile enterprise environments.

The online-softmax identity allows for lossless decomposition and merging of attention states, enabling efficient, chunked construction of memory for extremely long prefixes (e.g., a 16K-token prefix from four 4K-token forward passes). This compositional structure provides significant advantages in managing GPU memory and calibrating the system offline.

Case Study: Financial Compliance Bot

A leading financial institution deployed an LLM-powered compliance bot, requiring it to process thousands of pages of regulatory documents (long context prefix). Initially, using traditional ICL, the bot experienced slow response times and high operational costs due to the LLM re-attending to the entire rulebook for every query. This led to a 1.2x increase in query latency and significant GPU memory strain.

By integrating Attention-State Memory, the institution externalized the regulatory documents into a compact, lookup-based memory. This resulted in a 40% reduction in average query latency and a 75% decrease in memory footprint for prefix handling. The bot's accuracy in correctly interpreting regulations improved by over 8%, demonstrating the effectiveness of ASM in complex, long-context enterprise applications.

This shift allowed the company to scale its compliance operations efficiently, process a higher volume of inquiries, and significantly reduce infrastructure costs, proving ASM's value in real-world, high-stakes environments.
