Embedding quantization to 4bit is nearly lossless; 1bit works with reranking

Developers report that quantizing embeddings to 4bit is nearly lossless for search, and 1bit remains usable with reranking. Tests on DINOv3 embeddings show 1bit quantization plus reranking enables efficient image retrieval thanks to strong semantics.
