Model Checkpoint

A saved model state captured at a certain stage of training and reusable later.

The concept of a checkpoint is important not only for safety in large-scale model development, but also for iterative experimentation and deployment management. Intermediate versions can be used for benchmarking, error analysis, rollback, and branching into different fine-tuning paths. It provides operational control across the foundation model lifecycle.
