ZVex is a Zig NIF wrapper around Alibaba’s ZVec, which is a blazing fast in-process Vector Database.

Currently, i’m providing precompiled builds in Linux x86-64, MacOS ARM and Linux ARM64. I tried to build on windows but got bonked by some Zigler issues. So it does not support windows for now.

ZVec Features

• Vector similarity search with HNSW, IVF, and flat index types
• Multiple vector types – fp16, fp32, fp64, int4, int8, int16, binary32, binary64, and sparse vectors
• Distance metrics – L2, inner product, cosine, and MIPS-L2
• Quantization – fp16, int8, and int4 for reduced memory usage
• Schema-based collections with typed fields and index configuration
