Decide whether the team is still exploring many ideas or has already narrowed the creative direction.

Step 2

Run one high-volume concept test

Test how each tool behaves when the team needs multiple concepts quickly, not just one polished sample.

Run one review-heavy production test

Use a brief that goes through the same review and approval process as a real commercial asset.

It can be rational to keep Luma for ideation and Runway for controlled production if each tool wins a different stage.
