Musk: 'Apple lawsuit is a new dimension of fraud' vs. Altman: 'The highest benchmark is Musk's obsession'

Elon Musk and Sam Altman, CEOs of X and OpenAI, reignited a public feud over the Apple lawsuit dispute. Musk accused Altman of raising fraud to a 'new level,' while Altman retorted that the 'best benchmark is Musk's obsession' with him. Musk's X posts cited a user's claim that he had long warned Altman about fraud, now 'exposing the truth.' Altman responded by retweeting Musk's post, accusing him of selling short-term space datacenter prospects to investors, targeting Musk's space datacenter plans and SpaceX IPO. Altman later dismissed the GPT-5.6 launch, stating the 'greatest benchmark' remains Musk's obsession. Meanwhile, Musk's SpaceX AI released GPT-5.6 one day after 'Grok 4.5,' which initially showed strong coding improvements but was overshadowed by GPT-5.6's release. Artificial Analytics' Intelligence Index ranked Grok 4.5 eighth, below GPT-4.5 Terra. Their social media clash, last seen in May after a court case, resumed following a temporary truce to avoid disrupting judicial proceedings.
