According to DeepLearning.AI on X, the fastest way to improve an AI product is to expose early prototypes to real users so they can break them, turning failures into actionable feedback that accelerates iteration and product-market fit. As reported by DeepLearning.AI, small-scope tests reveal edge cases, data quality gaps, and UX friction that do not appear in lab demos, enabling teams to prioritize fixes with highest user impact. According to DeepLearning.AI, this approach reduces model risk, shortens feedback loops, and improves ROI by validating assumptions before scaling, which is critical for teams deploying LLM features, retrieval augmented generation, or agent workflows in production.
