  "account": "RealFeedApp generates cover images for its articles using its own bank of images, separate from the publisher-provided rights. Initially, the prompts for these images yielded dark, moody visuals with ample negative space, but when these images were scaled down for thumbnails, they appeared as black rectangles due to the minimal subject matter. The key takeaway was that prompts must be tailored to the final image size, not the preview size.\n\nSubsequent attempts to generate documentary-style images with a mandatory accent color resulted in the model inserting news graphic elements, such as colored bands and chyrons. This was not a malfunction, but rather the model's solution to the constraints imposed by the prompt. Each word in the prompt seemed harmless alone, but together they created an image the model deemed the most efficient way to satisfy all conditions.\n\nThe most surprising revelation was that changing the style of the images required rewriting the conceptual work itself, rather than just adjusting the lighting and rendering. A style is not a simple filter applied to a fixed set of ideas; it involves a new set of subjects and concepts.\n\nFinally, a practical warning was issued: before incorporating an image model into a commercially viable app, it is essential to verify the license of the model to ensure it permits commercial use. Several popular and high-quality models have non-commercial licenses, and overlooking this aspect could lead to legal issues after the app has been launched. The updated image bank in RealFeedApp now adheres to these guidelines, ensuring the appropriate licensing for commercial use.",
  "summary": "Every card in RealFeedApp has a cover image. They aren't fetched from the articles — publishers' images come with rights I don't have — so the app uses its own bank, generated ahead of time, one pool per topic. I generated that bank once, shipped it, and this month threw all of it away and started over. Twice over, actually, because there were two separate failures and only the first one was my…",
