Lightweight Prompt Compression Aims to Make On-Device RAG Practical
A paper proposes compressing retrieved context before it reaches the model, cutting the token load that makes retrieval-augmented question answering expensive on edge hardware.
A new preprint, "Less is More," targets prompt compression for question answering on edge devices. The setup is familiar. Agent-driven question answering uses retrieval-augmented generation (RAG) to feed extra context to a model and improve…
