Doc-to-Atom: Learning to Compile and Compose Memory Atoms

arXiv:2606.12400v1 Announce Type: new Abstract: Long input sequences are central to document understanding and multi-step reasoning in Large Language Models, yet the quadratic cost of attention makes inference both memory-intensive and slow. Context distillation mitigates this by compressing contextual information into model parameters, and recent work such as Doc-to-LoRA amortizes context distillation into a single forward pass that generates one LoRA adapter per document. However, producing a single monolithic adapter for all queries leads to irrelevant-query interference, limited compositio

Why this matters
Why now

The paper addresses a critical computational bottleneck in LLMs, specifically the high cost of processing long input sequences, which is becoming increasingly relevant as AI systems handle more complex, multi-document tasks.

Why it’s important

Improving efficiency in handling long contexts directly impacts the scalability and capabilities of advanced AI, enabling more sophisticated reasoning and document understanding in real-world applications.

What changes

The ability to more efficiently compile and compose 'memory atoms' rather than monolithic adapters could lead to more nuanced and performant long-context LLMs, mitigating issues like irrelevant-query interference.
