Cursor AI Agents Now Work Autonomously for 52 Hours, Completing Quarter-Long Projects in Days
Summary
Cursor AI agents now work autonomously for up to 52 hours straight, completing complex software projects like chat platforms and mobile apps in days instead of months, with high success rates and minimal human oversight required.
Key Points
- Cursor expands its long-running agents research preview to all Ultra, Teams, and Enterprise users, enabling autonomous work on ambitious projects for 25-52 hours with minimal human intervention
- The agents successfully complete complex tasks like building chat platforms, implementing mobile apps, and refactoring authentication systems by using upfront planning and multiple agents checking each other's work
- Users report substantially larger pull requests with high merge rates, compressing quarter-long projects into days while allowing developers to focus on other work as agents run autonomously
