Timescale 开源了 pg_vectorsearch，一个 PostgreSQL 扩展，其 PRISM 索引在查询和建索引速度上均优于 pgvector 的 IVFFlat 和 HNSW，支持 RaBitQ 量化、SIMD 优化和动态更新。
Turbopuffer announced a major storage architecture change ("turbopuffer v3") that demotes the ANN vector index from primary to secondary index, evolving the serverless database from a specialized vector search engine into a generalized search database supporting many more query plans at greater scale.
Turbopuffer announces beta support for late interaction, enabling models like ColBERT to represent text as token-level vectors, combining a fast single-vector ANN first pass with exact late interaction reranking to improve recall.
