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

Qwen Developer open-sourced zg (zvec-grep), a local-first search layer that unifies ripgrep, BM25, and vector search behind one interface for humans and coding agents. On a 20-question SWE-QA-Bench sample, it cut tool calls by more than half and input tokens by nearly half while raising the Judge score by 1.50 points. It reduces agents’ search-related spending and context-building work by adding local indexing, MCP wiring with two default tools, and output limits designed for token economy.
