Altman argued<\/a> there were \u201ca lot of benchmarks to suggest\u201d 5.6 Sol was the top AI model in the world, \u201cbut the most reliable way to tell is that elon is obsessed with me again.\u201d<\/p>\n Musk said in a post<\/a> early Saturday morning that Altman \u201ctakes scamming to a whole new level.\u201d<\/p>\n Altman responded to Musk\u2019s post, saying, \u201chomeboy you’re the one selling public market investors on short-term space datacenters,\u201d referring to orbital data centers Musk has championed and seeks to launch as a solution to AI energy limitations on Earth.<\/p>\n OpenAI and SpaceXAI both released the latest versions of their flagship AI models this week, with OpenAI releasing GPT\u20115.6 and SpaceXAI releasing Grok 4.5.<\/p>\n 5.6 Sol is the agentic version of ChatGPT, designed to handle multi-step tasks autonomously\u2014the same as Grok 4.5.<\/p>\n Forbes Valuation<\/p>\n We estimate Musk\u2019s net worth at $917.3 billion as of Saturday, about a month after he became the first trillionaire in history. Altman\u2019s estimated net worth is $3.4 billion.<\/p>\n GPT 5.6 Vs. Grok 4.5<\/p>\n OpenAI\u2019s latest model excels at broad reasoning and business workflows and cybersecurity, while Grok 4.5 is highly efficient at autonomous coding and developer workflows. SpaceXAI has boasted Grok 4.5\u2019s efficiency, as it is cheaper to use than GPT 5.6, though the OpenAI model outperforms Grok on some features including abstract reasoning.<\/p>\n Key Background<\/p>\n Tensions between Musk and Altman are at a high as their AI companies battle for supremacy. The two chief executives are just a few months removed from a lawsuit in which Musk, one of the founders of OpenAI, accused Altman of deceit and breach of contract by shifting the company from its nonprofit mission to a for-profit enterprise. Musk sought up to $150 billion in damages from Altman and vowed to appeal the ruling after a jury found he missed the deadlines <\/a>to file his lawsuit. Musk and Altman have repeatedly traded blows in recent years, mocking each other\u2019s businesses and lobbing personal insults<\/a>.<\/p>\n Further Reading<\/p>\n Musk To Appeal OpenAI Verdict: Lawyer Says ‘War\u2019 Is ‘Not Over’ <\/a>(Forbes)<\/p>\n
