Elon Musk on Friday praised his artificial intelligence company xAI's Grok model for its growing ability to craft sophisticated prompts that produce higher-quality images and videos, amplifying a user's tip in a post that quickly drew more than 1.6 million views.

In the message posted at 7:24 p.m. EDT on April 3, Musk responded to a video demonstration shared by venture capitalist Justine Moore, a partner at Andreessen Horowitz focused on AI investments. Moore had explained how she starts with simple ideas, feeds them to Grok for refinement, then iterates with the chatbot before generating final visuals using Grok's Imagine feature. "You end up with something much more detailed!" she wrote.
