AI agent evaluation tools shift focus from final answers to entire trajectories

Evaluating AI agents requires a different approach than assessing single LLM calls, focusing on the agent's entire trajectory rather than just the final output. Tools like LangSmith, Galileo, Arize Phoenix, Braintrust, Future AGI, and Langfuse offer varying capabilities for this, with some specializing in agentic workflows and others providing open-source observability. The key is to score not only the final answer but also the sequence of tool selections, arguments, and recovery from errors to identify true reasoning versus luck. AI
