TACHIOM gains HNSW-accelerated approximate clustering for late-interaction retrieval
lateinteraction · x · 2026-11-10
The late-interaction/multivector retrieval ecosystem keeps growing: a community PR lets TACHIOM work on images and other modalities without token IDs, and accelerates clustering with HNSW.
Concretely, @Robro612 submitted a PR implementing index-accelerated approximate assignment (CPU, HNSW, non-batched) as an alternative to TAC clustering — a technique discussed in the recent paper on late-interaction methods. Useful signal for anyone building ColBERT-style retrieval pipelines.
