为什么值得关注
Property Finder identified that 96.8% of their vision-AI evaluation labels were inherited directly from an incumbent model, obscuring actual performance metrics. By constructing an unbiased ground-truth dataset and applying evolutionary prompt optimization, they were able to properly evaluate alternatives and transition to a more accurate and cost-effective model on Amazon Bedrock. The update led to an 86% cost reduction across evaluations of 11 image-quality attributes.
