Building an agentic image generator that improves itself

The goal was to build a system that automatically improves the quality of images generated by the OpenAI API. To do this, we needed a robust evaluatorAn evaluator is an AI system that assesses the quality or characteristics of generated content. In the context of LLMs, evaluators examine outputs against specific criteria, providing feedback that can be used to improve generation quality. This creates a closed loop system where one model critiques another model's work. to detect imperfections—such as distorted text or weak visual appeal—and an iterative feedback loop to refine the image with each pass. Defining an Initial Prompt We began by defining an initial prompt to generate our ad. As shown below, we settled upon a prompt that included various distinct, challenging components for an image generation model to create. An ad for Redbull's summer campaign. It should include multiple flavors of RedBull, with lots of colors surrounding it. The image should be on a rooftop in SF, with ... Read full article.
