Grok 4.7 claims near-Opus 5 results on certain tasks

“Close to Opus 5 performance on certain tasks at a price of Grok 4.6” is how a post from the SpaceXAI account sums up Grok 4.7, pointing to xAI’s release page. It lists the model as live on Grok Build, Cursor and the APIs.

Elon has described Grok 4.5 as an “Opus-class” model, so comparisons with Anthropic’s Opus line are familiar ground here. Which tasks come close, and by how much, the post doesn’t say, and no benchmark figures travel with the claim. Odd, in our view, to hang the pitch on a rival’s model and then leave the numbers out.
