The risk assessment focused on model risks. PwC combined rule based scoring for binary and multiple choice questions, embedding similarity for consistency across repeated runs, and LLM based checks of reasoning answers: an LLM split each answer into clauses, an LLM as a judge compared each clause with retrieved passages of the source document to flag contradictions (a clause with no supporting passage counted as a hallucination), and a judge listed the parts of each question left unanswered. Because the production infrastructure was shared with other use cases, outputs were generated manually in a sandbox; because of confidentiality, PwC used its own prompts and ground truths for ten companies, which UOB reviewed. The case study therefore treats the results as a proxy for the production tool and publishes none of them.","pilot",2025,[27],"internal-tools",[29],"en",[],[32,36,39],{"url":33,"title":34,"publisher":35},"https://assurance.aiverifyfoundation.sg/report/pilot-participants-and-use-cases/","Pilot participants and use cases","AI Verify Foundation",{"url":37,"title":38,"publisher":35},"https://assurance.aiverifyfoundation.sg/wp-content/uploads/2025/05/Internal-GenAI-chatbot.pdf","Internal GenAI Chatbot: UOB x PwC",{"url":40,"title":41,"publisher":35},"https://aiverifyfoundation.sg/ai-assurance-pilot/","Global AI Assurance Pilot",{"level":43,"checkedAt":44},"source-verified","2026-09-28","C","uob-pwc-llm-judge-genai-chatbot-testing",[48],{"slug":17,"title":49},"AI copilot for model risk validation and monitoring",{"title":51,"useCases":52,"organization":54,"vendors":55,"summary":59,"stage":60,"year":61,"channels":62,"languages":63,"metrics":64,"outcomeDisclosed":11,"sources":81,"verification":86,"grade":88,"id":89,"useCaseTitles":90},"UOB: machine learning prioritisation of transaction monitoring alerts with Tookitaki",[53],"aml-alert-triage",{"name":6,"anonymized":12,"country":7,"region":8,"industry":9},[56],{"name":57,"role":58},"Tookitaki","platform","UOB co developed a machine learning anti money laundering solution with Tookitaki that sorts transaction monitoring alerts into three priority tiers and identifies connected parties, so investigators focus on the cases most likely to be suspicious.
