SpaceX launches Grok 4.5, its first coding AI built after the $60 billion Cursor deal, challenging Anthropic and OpenAI in enterprise AI.

Grok 4.5 is SpaceXAI's smartest model built for coding, agentic tasks, and knowledge work.

Elon Musk said the latest version of Grok is “faster, more token-efficient and lower cost” than one of Anthropic’s models.
