"Elon Musk and Sam Altman criticized each other in new posts on X," reports CNBC, "highlighting the billionaires' long-standing tussle over OpenAI's evolution."This week, SpaceX released the Grok 4.5 generative AI model, while OpenAI debuted its own GPT-5.6 Sol. For days, Musk and Altman have hyped up their respective releases, but on Saturday the rivalry got personal. In response to a post about Apple filing suit against OpenAI on Friday over alleged theft of trade secrets, Musk wrote, "Scam Altman strikes again ...." Minutes after his post, Musk doubled down, writing, "He takes scamming to a whole new level." Next, Musk published a photo of Altman that included the words, "I'm doing this because I love it." "By 'this' he means scamming," Musk wrote, including two rolling-on-the-floor-laughing emojis. Musk then replied to that post, writing, "He might literally love scamming more than any human alive!" The flurry of social activity got Altman's attention. "[H]omeboy you're the one sellling public market investors on short-term space datacenters," Altman wrote in an X post of his own that garnered over 11 million views. "We start flying them next year. Maybe you can come see them if your parole officer approves," Musk fired back. Separately, Altman put Musk's fresh wave of attention in the context of OpenAI's fresh model release. "[T]here are a lot of benchmarks that suggest 5.6 sol is the best model in the world right now, but the most reliable way to tell is that elon is obsessed with me again," Altman wrote on X. Reacting to another post, Altman wrote that he was "not afraid of apple, but i have tremendous respect for them. s-tier company," CNBC reports — leading to a sarcastic response from X's head of product. "Incredible trade secrets as well, some of the best." And CNBC notes that Musk "replied with a face-with-tears-of-joy emoji."Read more of this story at Slashdot.
