The 4-task average accuracy is based on results of JCommonsenseQA, JNLI, MARC-ja, and JSQuAD.
The 6-task average accuracy is based on results of JCommonsenseQA, JNLI, MARC-ja, JSQuAD, XWinograd, and JAQKET-v2.

Model	4-task average accuracy	6-task average accuracy

English benchmark

Using the EleutherAI Language Model Evaluation Harness, we found the bilingual-gpt-neox-4b performs comparably with English/multilingual models of similar sizes.

The average accuracy is based on results of Arc-Challenge, Arc-Easy, BoolQ, COPA, HellaSwag, OpenBookQA, PIQA, PROST, SWAG, and WinoGrande.

How to use the model

Notice: Since the model is sensitive to decoding hyper-parameters (e.g. temperature, top_p, top_k, repetition_penalty), it is suggested to explore the best setting for your task.

Tokenization

The model uses a sentencepiece-based tokenizer.

The tokenizer has a vocabulary size of 65,536.
It uses byte fallback to decompose unknown text pieces into UTF-8 byte pieces to avoid producing <UNK> tokens.
It can recognize consecutive whitespaces, newlines, and tabs to handle structured texts better.
We turned off the default behaviour of prepending leading whitespace because it is not beneficial for processing Japanese.
Specifically, single whitespace is always processed as one token so that any English word won't have a preceding whitespace like in many other tokenizers (e.g. _Hello).
- This decision trades the English processing efficiency for a unified way to treat whitespaces.
- It leads to a significantly lower loss of next token prediction on English data because whitespaces are easy to predict.
Don't forget to set use_fast=False to make the above features function correctly.
