Arize Phoenix tracing and evaluation for smolagents-powered agents

AI Impact Summary

Arize Phoenix now enables end-to-end tracing and evaluation for agents built with smolagents. By instrumenting tool calls with OpenTelemetry and OpenInference and streaming traces to Phoenix, teams can inspect inputs, tool invocations, and outputs in real time while using GPT-4o to assess relevance and quality. The workflow covers DuckDuckGoSearchTool, VisitWebpageTool, and RAG-style evaluations, plus integration with HfApiModel and the Hugging Face hub. Prepare for local or hosted Phoenix deployments and install telemetry packages (smolagents[telemetry], openai) to enable seamless end-to-end tracing and evaluation.
