Director-AI is an Open Source runtime library (Python, PyPI package "director-ai") that serves as a hallucination guardrail for LLM outputs. It evaluates responses against retrieved evidence across multiple stages (rules, embeddings, NLI) and can halt output at the Token level during streaming. The core is licensed under Apache 2.0; a commercial Pro Edition is available for purchase. Note: The sources describe a hallucination guardrail, not a video directing product; "dual-entropy scoring" is not documented in the sources found.
