SpaceXAI launched Grok 4.5, a model trained on tens of thousands of NVIDIA GB300 GPUs alongside Cursor. Grok 4.5 is priced at $2 per million input tokens and $6 per million output tokens, with roughly twice the token efficiency of comparable leading models. It is available now in Grok Build, Cursor, and the SpaceXAI console, though EU availability is expected in mid-July. Free usage is offered for a limited time.
