1. LangChain and Pay-i Detail How to Prove Agentic AI ROI in Financial Services

LangChain. LangChain’s Karan Singh and David Tepper published a post with Pay-i arguing that agentic systems have fundamentally different economics from traditional enterprise software and require specialized observability and governance to quantify business value. The post walks through two use cases built on LangGraph for orchestration and LangSmith for tracing and cost tracking: RFP processing automation, which extracts requirements and drafts cited responses, and AML compliance monitoring, which triages alerts and generates Suspicious Activity Report drafts. It sets concrete targets such as 95 percent requirements extraction accuracy for RFPs and a 60 percent reduction in false positives plus a 50 percent cut in investigation time for AML workflows.
