Trace & Evaluate Your Smolagents Agent with Arize Phoenix — real-time tracing and evals

AI Impact Summary

Arize Phoenix now provides end-to-end traceability and evaluation for autonomous agents built with Smolagents, exposing step-by-step tool invocations, data processing, and final outputs. It leverages OpenTelemetry instrumentation and a Phoenix-based evaluation loop (GPT-4o as judge) to measure relevance, accuracy, and latency of tool results, enabling real-time debugging. Operationally, this requires installing telemetry dependencies, running a Phoenix server (local or hosted), and wiring Smolagents through the tracer_provider, with potential data governance implications for telemetry data.
