Google DeepMind paper finds self-improving agents forget old tasks as they learn new ones
Overview
A Google DeepMind paper, "Are Self-Evolving Agents Continual Learners?", tests agents that edit their own prompts, memory, or skills and finds they lose earlier skills while learning new ones.
According to a report summarizing the paper, GEPA gained 6.2 points per task block on average but lost 4.3 points on other tasks, making it the fastest learner and also the method that forgot the most.
The same report says a later edit cut one rule's 15.5-point gain to 2.5 points. The paper's recommendations, as reported, are to keep task-specific rules separate and to retest old tasks after each update.
