Code Review
This pull request refactors the preparation of teacher inputs for OPSD in the GKD trainer by appending student responses to the teacher's message history and using the standard batch preparation method. A high-severity issue was identified where padding tokens from the student's generation were being included in the teacher's input, potentially causing data corruption or training failures. A suggestion was made to use the attention mask to strip these padding tokens before processing.
