When used as the SBERT backbone, XLNet yielded worse results than BERT in the SBERT experiments.
Summary
Swapping BERT for XLNet as the base model inside the sentence-embedding pipeline actually produced worse results, not better. This matters because it shows that XLNet's architectural advantages don't transfer to the sentence-representation task, so the system should treat BERT as the safer backbone choice for embedding workloads.
