SpaceXAI has launched Grok 4.5, a new model optimized for coding, agentic tasks, and knowledge work. The model was trained alongside Cursor using datasets covering science, engineering, and math, with reinforcement learning focused on multi-step software engineering.
- Grok 4.5 scores #1 on Harvey's Legal Agent Benchmark and excels at complex office work in Excel, PowerPoint, and Word.
- It is served at 80 TPS with twice the token efficiency of comparable leading models.
- Pricing is set at $2 per million input tokens and $6 per million output tokens.
The model delivers intelligent results more quickly and at lower costs, now serving as the default in Grok Build and available in Cursor.
