Interface HnswBuildOptions

Build-time HNSW parameters. Defaults tuned for 384-dim cosine on PKM data.

interface HnswBuildOptions {
    dim: number;
    efConstruction?: number;
    m?: number;
    maxElements: number;
    seed?: number;
}

Properties

dim: number

Embedding dimensionality (must match the corpus).

efConstruction?: number

Beam width during build. Higher efConstruction = better recall, slower build, no query-time cost. Default 200.

m?: number

Number of bidirectional links per node. Higher M = better recall but more memory + slower build. Default 16 (Malkov & Yashunin, 2018, §4.1).

maxElements: number

Maximum elements (caller's count of vectors); enables index pre-sizing.

seed?: number

Seed for build-time randomization (reproducibility in tests).
