NVIDIA has highlighted a hands-on walkthrough for using NVIDIA NeMo Relay to inspect how Nous Research’s Hermes Agent reaches an answer, including the agent’s calls, retries and execution traces across two example scenarios. The work, conducted with Nous Research and Teknium, puts the focus on agent observability: not just whether an agent returned the right result, but how much work it performed to get there.

Tracing the Agent’s Work

NeMo Relay is being shown as a way to inspect Hermes Agent runs, exposing calls, retries and trajectories behind a final answer.

example scenarios in the walkthrough

300s

default gateway idle timeout

cold one-shot test sessions

Validation Scale

2concurrent

10cold one-shot

The documented end-to-end check uses more cold one-shot sessions than concurrent sessions to verify capture behavior.

What Gets Exposed

Model call

Requests and responses can become traceable spans.

→

Tool action

Tool choices, arguments and retries can be reviewed.

→

Trajectory

Completed runs can be exported for debugging and evaluation.

Developer value

Trace capture helps explain unnecessary calls, bad tool arguments, subagent behavior and retry loops.

Operational limits

Teams still need correct provider routing, completed sessions and local configuration checks for reliable output.
