The premise
Untraced LLM apps surprise you on the bill and on the quality. Tracing inputs, outputs, and costs is non-optional past prototype.
What AI does well here
- Emit a structured trace per call (model, tokens, latency).
- Aggregate cost per feature or per user.
What AI cannot do
- Trace what you didn't instrument.
- Replay a non-deterministic call exactly.
