Cheng Lou, the engineer who worked on React.js and now works at Midjourney, retweeted a post from yuwen_lu. The post states that Fable 5.1 can figure out by itself how to write wild cursive. It includes a video demonstration of the output. The original message mixes English and Chinese to express surprise at the AI's ability to produce the complex calligraphy style without further guidance. No additional details on the model's training or verification steps appear in the visible post. The retweet stands as the only action recorded in the packet.
