A trace groups related requests into one workflow, so you can follow a multi-step agent loop or RAG pipeline end to end instead of staring at isolated calls. Infere lets you set a trace ID with a header and see every request, cost, and latency under that trace.
Why it matters
Agent workflows and RAG pipelines span many model calls. Without grouping, debugging means correlating isolated requests by hand.
How it works
A trace ID is attached to each request in a workflow, usually through a header. Every request, span, cost, and latency under that ID rolls up into one view, so you can follow a single user action end to end.
