arXiv:2606.05568v1 Announce Type: cross Abstract: While ColBERT is an effective neural retrieval architecture, it requires a heavy index structure to support candidate set retrieval based on approximated token embeddings, gathering and decompressing document token embeddings, and applying the MaxSim operation. Indexes in PLAID and similar ColBERT implementations require five to ten times the disk storage of the original raw text, which limits their scalability. Furthermore, prior work has identified that the gathering and decompression stages are the primary inefficiencies at query time. Limit
This research addresses current limitations in large language model (LLM) retrieval systems by proposing a method to optimize index size and query efficiency, crucial as LLM adoption scales.
Improved retrieval architecture efficiency directly impacts the scalability and cost-effectiveness of deploying large-scale AI applications, making advanced AI more accessible and performant.
ColBERT-based neural retrieval systems can now be implemented with significantly reduced storage requirements and faster query times, removing a key bottleneck for their wider adoption.
