The post discusses a new service utilizing OpenAI's image API to create personalized coloring books from family photos. While some users express enthusiasm about the concept, there are significant concerns about pricing, the quality of AI-generated images compared to handmade art, and copyright issues regarding the use of images of minors. Comments highlight the high cost of these books ($30 for potentially short-lived items) compared to cheaper, traditional options. There's a general desire for better personalization and a unique artistic style that stands out from common AI outputs. Moreover, the discussion considers how AI could work alongside traditional techniques to create more appealing products. The potential market for adult coloring books is also mentioned as a viable niche where this service could succeed.
