# What does this PR do? Superseeds huggingface#1459 The fix works as follows. We updated next_token_chooser to return all logprbs, then batch_top_n_tokens, now also gets accepted_ids + speculated_length (so it knows how to interpret the flat logprobs). We then update the code to return lists ot `Tokens` that it expects. <!-- Congratulations! You've made it this far! You're not quite done yet though.
