How to find and debug agent failures your evals are missing
TL;DR: Predefined evals and monitors measure risks you already know how to specify. Production agents also develop failures nobody thought to encode: a tool receives the wrong argument, a retry loop adds cost without making progress, or the final answer l

The future of AI operations teams

Agent cost management is about more than the model
Every LLM call your application makes costs money, and agentic applications make a lot of LLM calls. A single user request fans out into planning, tool selection, retrieval, and synthesis steps, each one a model invocation, and the bill for all of it land
