For Musk, the deal streamlines his businesses and solidifies the relationship between the former Twitter and xAI, which has used information from the social network to hone its chatbot. The deal also offers a resolution to X’s other backers following months of uncertainty over the state of their investment as Musk’s changes led to an exodus of users and advertisers.
“XAI and X’s futures are intertwined,” Musk posted. “Today, we officially take the step to combine the data, models, compute, distribution and talent. This combination will unlock immense potential by blending xAI’s advanced AI capability and expertise with X’s massive reach.”
