This is done to avoid hitting the maximum number of tokens that can be processed by the model on a single device. The window size and stride can be configured using the <code>window</code> and <code>stride</code> parameters. The default values are 510 and 255 respectively, which means that the model will process windows of 510 tokens, each separated by 255 tokens.

This is done to avoid hitting the maximum number of tokens that can be processed by the model on a single device. The window size and stride can be configured using the <code>window</code> and <code>stride</code> parameters. The default values are 510 and 255 respectively, which means that the model will process windows of 510 tokens, each separated by 255 tokens.
