A new research paper published on arXiv explores the long-term stability of AI companions, identifying two key failure modes: persona collapse and behavioral drift. The study introduces ANCHOR, a method to evaluate these failures across 2,008 conversations, revealing that current models struggle to maintain consistent personas and recall interaction history. The findings indicate that no tested configuration reliably preserves AI companion continuity, highlighting the need for audits that differentiate between persona enactment, trajectory recall, and deployment context.
