VectifyAI/PageIndex released v0.2.16 on 2026-09-10 at 12:09 UTC, MIT Python, 3,141 forks, 104 open issues. It builds a hierarchical document index the model reasons over directly, skipping embeddings and similarity search entirely. Notable against the same day's data, where Milvus (46,067 stars) and turbovec (16,963, up 91 today) are both pure vector-index plays, so the two approaches are gaining traction simultaneously rather than one displacing the other.
