I built QWED – a verification layer that sits between your LLM and production. The idea: Don't fix hallucinations, verify them. If AI output can't be mathematically proven, it doesn't ship. 11 specialized engines: - Math (SymPy) – verify calculations - Logic (Z3 SMT) – formal proofs - SQL (SQLGlot) – detect injection/dangerous queries - Code (AST) – security analysis + taint tracking - Facts (KB) – entity verification without LLM Works with ANY LLM – OpenAI, Claude, Gemini, or local models via Ollama ($0). Model-agnostic: Your LLM choice, our verification. Happy to answer questions about deterministic AI verification!
