Pick a winner
Once a Playground run shows a candidate is better, you promote it. Winner
selection is an admin action and is recorded with the exact run, variant, and
decision.
Step 1 — Open the winning run
On the Playground page, open the completed run that proves your candidate wins.
Step 2 — Select the winner
Click Select winner on the candidate variant. Confirm. EvalGate records:
- the exact run snapshot,
- the selected variant ID,
- the request hash,
- the decision actor and rationale.
Winner selection is admin-only. A non-admin can run the Playground but
cannot promote a variant.
Step 3 — Use the winner downstream
The winner feeds the next stages of the eval loop:
- An Experiment can be created from this Playground to confirm the win at
scale.
- A deployable artifact can be derived from the winning prompt, model, and
parameters.
- The Unified Eval Loop records this Playground as the “Playground
reproduction” stage.
What a winner is not
- It is not a deployment. You still publish and deploy the artifact separately.
- It is not irreversible, but the decision is immutable in history. To change
direction, run a new Playground and pick a new winner.

Carry the winner through Deploy an artifact.
