LLMs face persistent plasticity loss despite scaling, study finds

By PulseAugur Editorial · [2 sources] ·

A new arXiv paper investigates the challenge of plasticity loss in large language models (LLMs), where models struggle to learn new information after being trained on older data. Researchers found that this plasticity loss occurs even in modern transformer-based LLMs, including GPT-style models, and that the effect scales predictably with model size. While larger models may delay the onset of plasticity loss, the study suggests that simply increasing parameter count is insufficient to prevent it entirely, indicating a fundamental limitation for continual learning in LLMs. AI

IMPACT Suggests that scaling alone may not solve the continual learning problem in LLMs, potentially requiring new architectural approaches.
