Reducing Risk and Strengthening Client Trust with DPO

Challenge

A global financial services provider deployed a generative AI assistant to streamline client queries and support compliance teams. While adoption was strong, the AI assistant struggled to balance clarity, regulatory precision, and usability. Over-refusals frustrated employees and clients by blocking valid queries, while vague responses created compliance risks when regulatory nuance was essential. The client needed a way to optimize outputs quickly for compliance, organizational tone, and client trust, without adding unnecessary overhead.


DDD’s Solution

DDD implemented a Direct Preference Optimization (DPO) pipeline tailored to the financial domain. Compliance officers and financial analysts developed a custom rubric to evaluate responses on regulatory adherence, clarity, and tone. Thousands of ranked examples captured subtle differences between valid financial guidance, safe refusals, and policy-aligned disclaimers. The AI assistant was stress-tested with adversarial queries covering investment loopholes, disclosure boundaries, and cross-border regulations to ensure it could handle high-stakes situations reliably. By directly training on ranked human preferences, DPO enabled rapid optimization with fewer resources, making it well-suited for a fast-paced, regulated environment.
