- R · What Makes It Special
- Grok 4.5 (July 2026), SpaceXSI's smartest model for coding, agentic tasks and knowledge work at launch: trained alongside Cursor on tens of thousands of NVIDIA GB300 GPUs, with RL across hundreds of thousands of mostly software-engineering tasks, it scored 83.3% on Terminal-Bench 2.1 and 64.7% on SWE-Bench Pro while using about 4.2x fewer output tokens per task than Claude Opus 4.8. It runs at about 80 tokens a second, became Grok Build's default model and costs $2/$6 per million tokens.
