SpaceXAI has launched Grok 4.5, built on a 1.5-trillion-parameter architecture. Elon Musk called it an Opus-level rival to Claude — faster and priced at just $2 per million input tokens.
The Justice Department sided with xAI in an NAACP pollution lawsuit, arguing Grok runs Pentagon war operations in Iran — so the company's 57 unpermitted gas turbines cannot be shut down.
Former xAI safety engineer Devin Kim sued xAI and SpaceX, claiming he was fired for warning about Grok's antisemitic outputs, EU safety test evasion, and non-consensual imagery on X.
