NanoVDR distills 2B VLM to 69M text encoder for faster visual document retrieval

By PulseAugur Editorial · [1 sources] ·

Researchers have developed NanoVDR, a novel approach to visual document retrieval that significantly reduces computational costs. By distilling a large 2B parameter vision-language model (VLM) into a much smaller 69M parameter text-only encoder, NanoVDR achieves 95.1% of the teacher model's quality while drastically cutting down on latency and GPU requirements. This method decouples the encoding paths for documents and queries, recognizing that queries are typically simpler text strings requiring less complex processing. AI

IMPACT Enables faster and more efficient visual document retrieval by significantly reducing model size and computational demands.
