Could you build this?
Partial Compiling vector quantization routines to WebAssembly is feasible, but implementing Google's complex vector quantization algorithms with SIMD-optimized WASM requires low-level math and systems optimization skills.
What it would actually take: Requires implementing Google's TurboQuant algorithm in C++/Rust using SIMD vector intrinsics (WASM SIMD128) for high-performance distance calculation (dot product/cosine) and codebook lookups. The WebAssembly module must be bound to JavaScript/TypeScript via wasm-bindgen with efficient memory buffers to avoid serialization overhead. Doing this properly requires low-level systems programming and vector search math expertise.
Discussion
7 comments analyzed.
Competitors mentioned: OPQ (requires training), Google's multi embedding 2 model
Concerns raised: Slower than 32-bit float on query time (800ms vs 2.6ms in demo), Not worth using without GPU acceleration, Space savings marginal compared to retrieval speed tradeoff (1.2MB vs 7.2MB RAM but causes 1s latency)
