SpaceXAI has released Grok 4.5, the first model developed after its rebrand from xAI and trained in partnership with Cursor. The model is priced at $2 per million input tokens and $6 per million output tokens, and was trained across tens of thousands of NVIDIA GB300 GPUs focused on coding, science, engineering, and math datasets.
xAI has released Grok 4.5, pricing it at $2 per million input tokens and $6 per million output tokens — significantly undercutting Anthropic's Opus 4.7 ($5/$25 per million). Elon Musk claims the model delivers comparable performance to Opus 4.7 while being faster and more token-efficient.
Elon Musk's SpaceXAI has released Grok 4.5, priced at $2 per million input tokens and $6 per million output tokens. The model, trained alongside recently-acquired Cursor, is positioned as a coding and enterprise tool that claims to outperform Claude Opus 4.8 on several benchmarks while undercutting it on price by 60-76%.
