Grok 4.5 is a joint model from Cursor and SpaceXAI for long-running tasks across software engineering and knowledge work. It combines the Grok base with continued training on trillions of tokens of Cursor data and reinforcement learning on difficult, realistic problems.

## Strengths

- Handles long-running tasks that require using tools, checking results, recovering from mistakes, and adjusting its approach.
- Applies broad knowledge to software engineering, data science, finance, research, legal work, and other computer-based tasks.
- Solves multistep tasks in under half the steps of comparable frontier models.

## Tools

Grok 4.5 has access to all agent tools when used with Cursor, including:
