Topline
OpenAI CEO Sam Altman lauded the company’s latest AI model, GPT‑5.6 Sol, as the world’s leading model, citing Elon Musk’s renewed focus on the technology as additional evidence of its quality. Musk had previously accused Altman of deception.

Key Facts
Altman noted that a broad range of benchmarks support GPT‑5.6 Sol’s position as the superior AI model, and he viewed Musk’s renewed attention as further confirmation of its excellence.
On Saturday morning, Musk posted a critique accusing Altman of “taking scamming to a whole new level.”
Altman responded by saying, “You’re the one selling public‑market investors on short‑term space data centers,” referencing Musk’s plans for orbital data centers as a solution to AI energy constraints on Earth.
Both OpenAI and SpaceXAI introduced new flagship models this week: GPT‑5.6 Sol from OpenAI and Grok 4.5 from SpaceXAI.
GPT‑5.6 Sol is the agentic iteration of ChatGPT, engineered to autonomously handle complex, multi‑step tasks—mirroring the capabilities of Grok 4.5.
GPT 5.6 vs. Grok 4.5
GPT‑5.6 Sol excels in broad reasoning, business workflows, and cybersecurity, whereas Grok 4.5 demonstrates high efficiency in autonomous coding and developer workflows. Although Grok 4.5 is priced lower, GPT‑5.6 performs better in abstract reasoning and other advanced tasks.
Key Background
The rivalry between Musk and Altman intensifies as their respective AI enterprises vie for dominance. The two leaders are only months removed from a lawsuit in which Musk, one of OpenAI’s founders, alleged that Altman violated a non‑profit agreement by transforming the company into a for‑profit entity. Musk sought up to $150 billion in damages in a case that ultimately did not meet filing deadlines. Their public exchanges have included personal jabs and public criticisms over the past years.
