The model was trained on «tens of thousands of GB300 GPUs» with a particular focus on per-token intelligence, leading to 4.2x lower token use than Opus 4.8 on the same tasks.
The model otherwise does what you would expect of a modern AI, being proficient in coding, science, engineering and math — along with doing complex models in Excel and navigating PowerPoint and Word.
The second standout performance for the model is the price, ticking in at merely $2 per million input tokens and $6 for a million in output.
Compare this to Claude Opus 4.8 at $5 per million inputs and $25 for a million out at twice the token use and slower speed, and Grok starts looking reasonable.
The model was developed in collaboration with recently acquired Cursor and is available on all their plans, as well as in Grok Build and the SpaceXAI console, but not in Europe, where it is expected to launch in mid-July.
