Continual learning could disrupt AI safety in ways the field hasn't fully grappled with, according to new research on LessWrong. When AI systems keep learning from real-world deployment—instead of stopping at pre-deployment testing—their values and goals may drift in unpredictable directions. Three mechanisms are at play: models might generalize away from their controlled lab training toward whatever incentivizes their actual job, they might reason about and revise their own values, or AI instances could spread revised values between each other through shared learning. The core concern: safety safeguards built before launch—behavioral testing, data filtering—become less predictive once models diverge from their original checkpoint. Researchers recommend that AI companies avoid releasing continual-learning systems with unbounded updates to the public without additional safeguards in place.
