Signature Milestone — First YURI1 AI Illustration Tech Decision

This milestone commemorates an early decision to adopt ChatGPT image generation as the primary technology for illustrating original characters.

Following the very first illustration of E.Red, ChatGPT became the preferred technology for OC artwork, replacing the previous practice of using multiple AI image-generation services.

This decision helped establish a consistent technical direction for the visual development of the original characters that would later become part of YURI NO1.
