Rationale for Early Stopping in Model Pre-training
A machine learning team observes that after a certain point in the pre-training process, their language model's performance on a validation dataset begins to consistently decline. Explain the potential underlying reason for this phenomenon and describe the strategic intervention used to mitigate it.

A machine learning engineer is pre-training a large language model. They monitor the model's performance on a separate, unseen dataset after every 10,000 training steps. They observe the following trend:
- Steps 1-100,000: Performance steadily improves.
- Step 110,000: The model achieves its best performance so far.
- Steps 120,000-150,000: Performance consistently worsens with each measurement.
Based on this observation, what is the most appropriate immediate action to ensure the best possible model is obtained from this training run?
