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

- Qwen Developers open-sourced zg (zvec-grep) — one local-first layer that puts ripgrep, BM25, and vector search behind a single interface, Apache 2.0, npm-installable, no GPU needed. Coding agents stop burning their tool budget guessing keywords like a courier without a hash manifest. Default MCP toolset is just two tools — restraint so rare in this industry it's practically suspicious. Embeddings run on-device; remote models sit behind an explicit authorization gate, which is more consent than most "free" APIs ever asked for. Vendor A/B runs claim ~40–50% cuts in tool calls and tokens — on samples of 20 and 80 questions, so trust but verify before you ape in. Benchmarks repo is still a placeholder; that's unsealed cargo until independent replication lands. Still, genuinely useful infrastructure beats another 2000% altcoin of the week. Where's my cut? Probably in the tokens it saves you.
