 Point `base_url` at any other compatible endpoint (llama.cpp, vLLM, LM Studio, a local proxy) and it just works. The pipeline benefits from models that expose a `reasoning_content` field (used by the Quality Agent's 8-dimension scoring) and strong multilingual output (used by the Translator Agent), but neither is required.
