Say HFresh uses "hybrid 8 & 1-bit"

| [HFresh indexes](/weaviate/concepts/vector-index#hfresh-index) are cluster-based vector indexes that use HNSW for the centroid index. They partition vectors into posting lists (clusters) and search only the most relevant clusters for a query. | ||

| HFresh indexes are well-suited for very large collections where memory efficiency is a priority, especially with high-dimensional vectors. They use mandatory 1-bit rotational quantization (RQ) for compression. |

It uses 1-bit rotational quantization for postings and 8-bit rotational quantization for centroids.
