Cross-Model Memory Transfer via Target-Side Reader Adaptation
Engram, cross-model memory transfer, reader adaptation, frozen memory, external knowledge
Introduces Engram: an external, addressable memory table decoupled from model weights Shows frozen memory from one LLM can be reused by another LLM when paired with a compatible or adapted reader Achieves 38.8 average score on QA tasks in controlled cross-model reuse — nearly matching same-model performance
Emphasizes architectural novelty and downstream utility while minimizing discussion of memory fidelity, update mechanisms, scalability limits, or real-world deployment constraints.
Foundational systems innovation enabling modular, auditable, and transferable knowledge storage for LLMs.
Engram enables cross-model memory reuse via lightweight reader adaptation, nearly matching same-model performance on QA tasks.
No discussion of memory update latency or versioning; No comparison to production retrieval-augmented systems (e.g., RAG with dense retrieval); No analysis of reader training cost or inference overhead
The story uses titles, institutions, awards, rankings, partners, experts, or official language to make the subject feel more credible. Watch for loaded terms such as reusable external knowledge artifact, middle regime, nearly closes the gap. The distribution reads as academic distribution. A pressure point: No discussion of memory update latency or versioning.
A dual-layer, four-branch reader nearly closes the gap between same-model and cross-model reuse, achieving an average score of 38.8 under our controlled evaluation protocol.
In downstream question answering tasks, a dual-layer, four-branch reader nearly closes the gap between same-model and cross-model reuse, achieving an average score of 38.8 under our controlled evaluation protocol.
