Valyu

A company selling search and retrieval infrastructure to AI systems: a Search API, a DeepResearch API, and an MCP endpoint, over an index it describes as petabyte-scale and spanning the open web, financial filings, academic papers, clinical trials, patents, market data, and licensed proprietary content. Everything here comes from Valyu's own site, so treat the scale claims as the company's.

It reaches this wiki through one engineering post, valyu-billion-scale-vector-index, and it is this spoke's first operator — a business whose product depends on how fast a Hamming distance runs. The other sources here are catalogues, textbooks and benchmarks written by people studying the tricks; this is a company whose ingest rate is set by them.

That difference is the reason to keep the page. When the spoke asks "does anyone still hand-optimize bit operations, or did the compiler win?", the useful evidence is not another benchmark of abs without a branch. It is someone with a commercial reason to care, publishing the profile.
