AI-assisted summary based on the listed source.

Recursive self-improvement requires agents to turn accumulated experience into better future behavior. Personal AI agents offer a concrete setting for studying this capability because they retain preferences, task histories, tool routines, and learned skills across sessions. Yet whether retained experience...

Understanding if and how AI agents can recursively self-improve is crucial for developing more effective personal assistants that adapt and optimize their performance based on past interactions. PAST-Bench provides a concrete framework to measure this capability systematically.
