Structured Memory for Edge Language Models: Persistent Context and Corpus Retrieval via O(1) SSM State Injection
arXiv cs.AI · Published · 3 min read
In 30 seconds
- What happened
- Researchers introduced PRECOG, a retrieval method for edge language models using State-Space Models that reduces prefill latency from 27 seconds to under 6 milliseconds by pre-encoding document corpora as fixed hidden states.
- Why it matters
- Engineers building retrieval systems for resource-constrained devices or edge hardware need interactive response times and want to avoid the memory overhead of transformer KV-caches.
- Watch out
- The approach is demonstrated on a single 1.2B-parameter SSM model; generalization to other architectures, larger models, and real-world retrieval quality at scale remain unvalidated.
