SpaceXAI released Grok 4.5, its new flagship model trained on tens of thousands of Nvidia GB300 GPUs. It targets complex coding, agentic workflows and knowledge work, delivering strong benchmark results at lower cost than leading competitors. The model is available immediately via Grok Build, Cursor and the xAI API, with a free trial period. EU rollout is delayed until mid-July for regulatory reasons.
