Musk reposted a tweet from software engineer mattyp, which explained how software development has evolved into "data labeling" and introduced the process of building website characters using the AI model Grok. Mattyp stated that he drew inspiration from the X platform, using bots to crawl examples and creating a sliding interface to judge character traits, which were then used by cloud agents to generate new appearances. Ultimately, Grok was responsible for recreating the actual project and performing vectorized rendering.
