What happened
SpaceXAI launched Grok 4.5, its most intelligent model to date, designed for coding and agentic tasks, trained on tens of thousands of Nvidia GB300 graphics processing units with meticulous data filtering. The model is immediately available through Grok Build in Cursor and the SpaceXAI console via API, with EU availability expected mid-July. Priced at $2 per million input tokens and $6 per million output tokens, CEO Elon Musk stated it is an "Opus-class model, but faster, more token-efficient and lower cost." This follows SpaceX's $60 billion all-stock acquisition of Anysphere, Cursor's parent company, announced last month.
Why it matters
Grok 4.5's pricing at $2 per million input and $6 per million output tokens significantly shifts unit economics for agentic workflow deployment, undercutting Anthropic's Claude Opus 4.8 by 60% on input and 76% on output. For platform engineers and procurement teams, this offers a lower-cost alternative for integrating advanced coding agents, particularly after SpaceX's strategic acquisition of Cursor. This aggressive pricing intensifies competition, especially as OpenAI's GPT-5.6 Luna, launching this week, offers a $1 per million input token price while matching Grok 4.5's $6 per million output token price.
