A netizen used Grok 4.5, a conversational AI developed by X.AI Corp, to identify a restaurant from a photo of singer and painter Solbi's autograph. Elon Musk retweeted the netizen's post demonstrating Grok's performance, leading to opinions that Solbi received a shoutout. Solbi responded by inviting Musk to Korea, saying, "Tesla boss, come to Korea to get my autograph."
