ClearBank: Safeguarding generative AI use cases in a regulated fintech banking API

ClearBank runs retrieval-augmented LLM use cases inside its banking API (enquiries monitoring, a policy-review bot and client screening) on its own infrastructure, and assures every pipeline the same way: routine retrieval and response evaluation for document specificity, precision, answer correctness, hallucination and toxicity, ROUGE for summarisation, and human review, so domain experts can tune models in a safeguarded environment.
