SpaceXAI launches Grok 4.5 for coding, agents and knowledge work
SpaceXAI released Grok 4.5, its strongest model yet for coding, agentic tasks and knowledge work, trained alongside Cursor across tens of thousands of NVIDIA GB300 GPUs. The model is available today in Grok Build, on all Cursor plans and via the SpaceXAI API at $2 per million input tokens and $6 per million output tokens, with about 80 tokens per second serving speed, roughly 2x token efficiency versus comparable models and limited free usage in Grok Build and Cursor; EU availability is expected in mid-July.
