Altman Calls OpenAI's 5.6 Sol Best Model as Musk Revives Scamming Attack
3 articles · Updated · Forbes · Jul 11
Summary
Sam Altman said OpenAI’s 5.6 Sol is “the best model in the world right now,” framing the claim as proof that Elon Musk is “obsessed” with him again.
Musk had accused Altman of taking “scamming to a whole new level,” prompting Altman to fire back that Musk was pitching investors on short-term orbital data centers for AI.
OpenAI and SpaceXAI both updated flagship systems this week, with GPT-5.6 and Grok 4.5 competing in the same agentic category built to handle multi-step tasks autonomously.
Benchmark claims remain split: OpenAI says 5.6 Sol leads in broad reasoning, business workflows and cybersecurity, while SpaceXAI touts Grok 4.5 as cheaper and stronger for autonomous coding.
The exchange extends a broader feud between the two AI rivals, months after Musk sought up to $150 billion from Altman in a lawsuit and vowed to appeal after losing on filing deadlines.
