Pinecone Open-Sources VQ-Bench Vector Quantization Framework

Pinecone released VQ-bench, an open framework for building and comparing vector quantization methods. It defines 7 primitives, expresses 25 quantizers through them, and includes a benchmark of 14 methods on 5 datasets; code is on GitHub under MIT.

• Framework defines 7 primitives, expresses 25 quantizers
• Benchmark covers 14 quantizers on 5 VIBE datasets
• PQ and OPQ had lowest reconstruction error; EDEN encodes faster
• Code on GitHub under MIT, includes Rust utility vqb
