Until this week, CodeSage ran its two models exactly as they ship on Hugging Face: Jina's code embedder and the ms-marco MiniLM reranker. A full index of php-src took 1,782 seconds, just under half an hour, and I got tired of waiting. CodeSage 0.38 does the same full index in 373 seconds. Nothing was retrained. The weights are the same weights; what changed is the inference graph around them, a few things in the chunker, and one SQLite query that had been quietly eating most of the run. The two rebuilt models are now public on Hugging Face, along with the scripts that produce them byte-for-byte. What CodeSage gives an agent CodeSage is a code intelligence engine for AI coding agents: a structural graph (symbols, references, dependencies) plus semantic search (embedding retrieval with cross-encoder reranking), in one Rust binary that works as a CLI or an MCP server. An agent asks it questions grep can't answer, like "what depends on this class" or "where does session handling happen", and gets file-and...
