With the roll out of AI model Grok 4.5, Elon Musk's xAI has closed the gap with rivals Google, Anthropic and OpenAI, analysts say.

XAI has rebranded to SpaceXAI, debuting a new logo and X handle. Elon Musk previously said the Grok maker would be folded into SpaceX.

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