arXiv:2605.26097v1 Announce Type: new Abstract: Models trained on a new task typically degrade on prior tasks, a phenomenon known as forgetting. Traditionally, mitigating forgetting has required replaying stored exemplars from prior tasks, which is often impractical. By contrast, language models can sample from their own training distribution, and we show that these self-generated samples serve as effective replay data, nearly eliminating forgetting. We find that forgetting nonetheless persists when the model has little remaining capacity: models pretrained close to saturation cannot absorb ne
The rapid advancement and deployment of large language models are highlighting practical challenges like catastrophic forgetting, making novel solutions vital for continuous learning systems.
This research suggests a fundamental shift in how AI models can manage new information without significant degradation of prior knowledge, increasing their utility and reducing operational costs.
Language models can potentially reduce dependency on external data storage for mitigating forgetting, extending their lifespan and adaptability in dynamic environments.

Language models could autonomously manage catastrophic forgetting by generating their own replay data.
This capability could lead to more robust and continuously learning AI systems requiring less human intervention for retraining.
The reduced need for external data storage for replay could lower the operational costs and environmental footprint of maintaining large AI models.
