XPost update

As seen on the 24/7 Wall St. homepage on July 11, 2026.

Musk is positioning xAI's Grok as the most cost-efficient frontier AI model by compute, a direct shot at OpenAI and Google's offerings.

@peterrhague @wholemars Our token efficiency seems to be better than any other AI model and we see many more ways to improve inference per watt, so I think Grok will continue to be the best value for money of the frontier models
