  1. SpaceXAI Reported

    SpaceXAI said Grok 4.5 is about twice as token-efficient as other leading models, and Musk said it is roughly on par with Anthropic's Opus 4.7 but faster. Neither claim has been independently tested.

  2. Elon Musk Reported

    Said in a reply on X that the cost of serving Grok Bot was unsustainably high relative to revenue. Users were reported to be running out of weekly allowances days early; no cost figure was given and the report does not say whether allowances were cut.

  3. Anthropic Reported

    Anthropic's IPO filing was reported to say it expects to pay about $3.1 billion a month once all contracted SpaceX compute is delivered, expected by the end of 2026, with either side able to cancel on 90 days' notice after early 2027.
