Semble, an open-source code search tool for AI agents. It combines static Model2Vec embeddings (potion-code-16M) with BM25, fused via RRF, and reranked with code-aware signals. It runs on CPU without transformers.

A token-efficient, fast, and accurate alternative to grep+read for AI agents (Claude Code, Cursor, Codex, OpenCode) when searching large codebases. It claims 98% fewer tokens than grep+read and 99% retrieval quality of a 137M-parameter transformer, while being ~200x faster. It is zero-config, requiring no API keys, GPU, or external services.

Semble addresses a critical operational bottleneck in AI agent development for code interaction. High token costs and slow performance of traditional methods like grep+read severely limit agent utility on large codebases. Semble's 98% token reduction and 200x speed improvement offer a significant...
