Research direction
Start by reviewing the attached screenshot and the KTO full-parameter training implementation, then identify where logits, chosen values, and KL are computed or logged. Reproduce the reported scale and zero KL with the same training setup; done means the cause is identified and the metrics are numerically correct.
