Inputs, prompt conditions and scoring
What the model receives
Each call supplies one source ad and brand context for an invented brand, then asks for one new concept. The aim is to adapt the useful creative mechanism to the new product. The full media mode covers six source ads; output counts can also include repeats and both prompt conditions.
What changes between prompts
Both conditions receive the same brand context and line-specific inputs, with a 150-word concept limit. The simple prompt states the task. The scaffold adds judging criteria, an ad-quality framework and a hook/narrative/visual/conversion structure. It therefore tests that whole package of guidance, not a single wording change.
How the result is scored
Ben blind-scores commercial potential, creative innovation, and coherence/suitability on a 0–10 scale. A concept clears the test-worthy threshold only when every dimension reaches 8. The displayed mean summarises quality; it does not measure the ad's eventual conversion rate. Scoring hides model labels, although the scaffold's formatting can reveal the prompt condition.
