# AI-generated summaries

> Sessions, traces, and test results open with an AI summary, so you don't reconstruct what happened span by span.

Openlayer generates **AI summaries** on three surfaces, so you can understand
what happened without reading raw spans or row-level results:

* **Sessions** — the session detail view opens with a summary of how the
  session actually went across its traces: what the user was trying to do,
  what the agent did, and where it struggled.
* **Traces** — the trace detail view shows a summary of the trace instead of
  requiring line-by-line span reading.
* **Test results** — results include a summary of the dominant failure modes,
  and you can drill down from each failure mode to the exact rows behind the
  pattern.

## Where to find them

* **Session summary**: open a project with tracing → **Sessions** → open a
  session. The summary appears at the top of the session detail view.
* **Trace summary**: open a trace from the **Traces** view.
* **Test-result summary**: open a test result — the summary sits above the
  row-level results; failure-mode entries link to their matching rows.

Summaries are generated on demand and cached, so opening the same session or
result again is instant.
