Code Review
This pull request introduces a small but effective optimization in the _create_chat_logprobs method. By checking whether the output format should be a token ID before decoding the token, it avoids an unnecessary and potentially expensive tokenizer.decode() call. The change is correct, well-contained, and improves efficiency. I have no further comments.

Small optimization to skip redundant detokenization step when token_id is instead requested.
