Today we are releasing Grok 4.5 together with SpaceXAI, our most intelligent model and the first we've built for more than software engineering.

Grok 4.5 can handle difficult, long-running tasks that require creatively using tools to solve problems, whether in software engineering, data science, finance, legal work, or anything else you do on a computer.

Cursor subscription plans for individuals and teams include significant usage of the model with double usage for the first week. We've also added new safeguards reflecting the model's cybersecurity capabilities.

A strong foundation

Grok 4.5 is a mixture-of-experts model that we trained jointly with SpaceXAI.
