Live LLM Output Exposes Agentic System Failures Missed by Offline Tests

A developer building an environmental compliance agent for Peru discovered significant issues when integrating a live Qwen qwen-plus model, despite passing all offline tests. The system, designed for auditability, encountered problems with inconsistent status values, empty task plans, varying citation field names, and unscheduled report saves. These issues highlight the limitations of offline testing for agentic systems, as real-world model output can expose failures in distribution and labeling that code-based tests cannot predict. AI

IMPACT Highlights the critical need for robust real-world testing of LLM-powered agentic systems beyond offline simulations.
