NVIDIA tutorial: use NeMo Relay to trace Hermes Agent runs and inspect ATOF/ATIF/OpenTelemetry traces
NVIDIA published a tutorial showing how to use NeMo Relay as a common observability layer for agent runs, with Hermes Agent producing ATOF event streams, ATIF trajectories, and OpenTelemetry spans that can be inspected in tools like Arize Phoenix; the repo includes runnable examples, verifiers, and setup instructions. A Hermes ToolPerf case study included with the tutorial compared baseline and fixed harness revisions across repeated runs, finding Qwen Coder 30B recovered more tasks but at the cost of increased calls, data, and latency.
