如何构建 AI 图像生成的评估管道

At Vets Who Code, we automated the generation of retro hero images for blog posts using Imagen 4. However, despite clear instructions, the AI occasionally inserted text into the images. To address this issue, we developed an automated evaluation test harness. The requirements for the generated images were strict, including a bold navy/red/white color palette, no text or typography, and a retro poster aesthetic. While Imagen 4 is powerful, its non-deterministic nature led to random text appearing in some images, making manual quality assurance unscalable. By implementing automated evaluation, we effectively resolved this issue and ensured that the generated images met the expected standards.
