## Summary

A recent paper explores the intersection of continual learning (CL) and model merging (MM), focusing on the challenge of task interference that arises when models are trained on multiple tasks sequentially. The authors present the Muon optimizer, a novel approach designed to mitigate this interference, thereby enhancing the performance of models in continual learning scenarios. Through various benchmarks, the paper demonstrates that the Muon optimizer significantly improves the ability of models to adapt and retain knowledge across tasks without suffering from the detrimental effects of interference.

## Key takeaways
