ev-rag

A retrieval-augmented knowledge bot for electric vehicles — engineering fundamentals, brand/model differences, charging, and self-driving. Ask anything and it retrieves from a 44-source, ~2,950-chunk corpus and answers with inline citations — it won't fill gaps from general knowledge, and if the sources don't cover it, it says so.

Local BGE embeddings → Supabase pgvector → DeepSeek, served on AWS Lambda. Query auto-routing + cross-brand comparison balancing, validated by a golden-set eval.
