Research direction

Start by reproducing the out-of-memory error at the save_pretrained method while fine-tuning on a custom dataset. Gather the model, dataset, hardware, and memory details, then trace the save operation to identify where memory rises. Done means the cause is documented and a verified fix or actionable workaround is available.
