Case Study: Leading Fortune 100 Company achieves more accurate, natural AI-generated ad imagery with Sama

How the advertising division at a Fortune 100 company improved the performance of its custom ad generation model.

Leading Fortune 100 Company’s advertising division wanted to scale custom ad imagery by using Gen AI to place products into contextual, realistic backgrounds. To ensure generated foregrounds blended seamlessly with new settings, the client engaged Sama to evaluate their Gen AI model and establish a human-in-the-loop validation and scoring process.

Sama implemented structured QA checks (quality, relevance, naturalness), had data experts accept or reject images to build training datasets, and used those labels to fine-tune the generative model. The work reduced model hallucinations, improved accuracy and ad performance, and — using Sama’s human-in-the-loop approach and platform — helped accelerate getting AI/ML models into production (up to 3x faster), yielding a better client experience and increased confidence in advertising services.
