What this means for you
Nothing to do yet. The switch is free — same $2/$6 rate, same speed as 4.6 — but no scores are published, so there is no evidence the larger base model or longer training run changed anything you would notice. Test it against 4.6 on your own tasks before migrating.
SpaceXAI has released Grok 4.7, its new flagship model, at the same $2/$6 rate and the same serving speed as Grok 4.6. It is built on a larger base model and a longer reinforcement learning run (training against a reward signal rather than worked examples alone). It ships as a hosted model, callable as grok-4.7. The release note gives no benchmark scores, no evaluation date and no context limit, so what the larger base model bought is unmeasured.
