How uniopen customized Amazon Nova to their retail moderation policies for production deployment

Uniopen leveraged Amazon Nova 2 Lite as the foundation for its retail content‑moderation system, applying supervised fine‑tuning inside Amazon SageMaker AI to align the model with its specific policy requirements. Prompt optimization was then used to further steer responses toward the desired moderation outcomes, while a series of business‑relevant evaluation and release gates ensured that only high‑quality outputs entered production. The result was a policy‑compliant moderation pipeline that could be deployed at scale via SageMaker endpoints, with clear checkpoints to maintain quality before live use.

⚡ Key Takeaways

• Amazon Nova 2 Lite served as the base LLM for the moderation task.
• Fine‑tuning was performed with supervised learning in Amazon SageMaker AI.
• Prompt optimization was applied to tailor the model to Uniopen’s moderation criteria.
• Business‑relevant evaluation and release gates were introduced to verify quality pre‑deployment.
• The approach required integration with SageMaker pipelines and custom moderation metrics.
• WhyItMatters: Engineers building production moderation systems can adopt a similar fine‑tuning and prompt‑engineering workflow within SageMaker to quickly adapt a pre‑
