Qwen Developers Open-Sources zg (zvec-grep): A Local-First Search Layer Unifying ripgrep, BM25, and Vector Search

We look at zg (zvec-grep), the local-first search layer that Qwen Developers just open-sourced under Apache 2. 0. We explain how it puts ripgrep, BM25, and vector search behind a single interface, so an agent can move from a plain-language description to an exact line span without switching tools.

We cover the deliberately small MCP surface, the on-device embedding catalog, and the authorization gate that stands between local content and remote models.
