SpaceXAI has released Grok 4.5 at a highly competitive $2 per million input and $6 per million output tokens, delivering a claimed two-fold increase in token efficiency to challenge Opus-class performance at a fraction of the cost. For production pipelines, this drastically lowers the cost barrier for complex knowledge work and coding tasks, allowing you to run heavy agentic workflows for less than half the price of Anthropic's Opus 4.7 or OpenAI's Sol.
Grok 4.5 matches Opus 4.7's performance at 60% lower input and 76% lower output token costs, making it the most cost-efficient high-end model available. This lets teams deploy Opus-tier capabilities at scale without budget overruns, undercutting competitors on price while maintaining quality—forcing rivals to slash costs or lose customers.
