Overview of Japanese LLMs

[ English | Français | 日本語 ]

Evolution of parameter sizes for Japanese LLMs and non-Japanese LLMs. The information on the Japanese models is derived from this article, while the information on the non-Japanese models can be referred from the Models table on LifeArchitect.ai. However, due to space constraints in the figure, some models have been omitted. Additionally, estimates are included in the parameter count for non-Japanese models. Please notify us of any corrections, additions, or updates.

A list of publicly available LLMs trained with a focus on Japanese, along with their evaluation benchmarks, maintained by volunteers from various sources like academic papers and other public resources.

::: warning Caution

We can't guarantee the accuracy or completeness of any information here.
Some information is based on conjecture and might not reflect your specific use case.
While many models are released under permissive licenses like MIT or Apache 2.0, some are subject to more restrictive terms including non-commercial use clauses (e.g CC BY-NC-SA 4.0) or other stipulations. :::

Please point out any errors on the issues page. Feel free to contribute directly with a pull request.

Evaluation Benchmarks for Japanese LLMs

Hybrid Benchmarks

	Description	Developer
Nejumi LLM Leaderboard3	Evaluates the Japanese language capabilities of LLMs from three perspectives: language understanding ability, application ability, and alignment (including controllability and safety). For more details, see this article.	Weights & Biases
Japanese LLM Evaluation	Conducts a comprehensive evaluation of various LLMs based on three types of tasks: Japanese language understanding and generation tasks, Japanese multi-turn dialogue tasks, and English language understanding and generation tasks. Also publishes swallow-evaluation, an evaluation script that integrates and improves existing LLM evaluation tools.	Swallow Project

Traditional Benchmarks based on Natural Language Understanding tasks

	Description	Developer
Open Japanese LLM Leaderboard	Evaluates Japanese language models in 16 different tasks using llm-jp-eval.	LLM-jp, Hugging Face
llm-jp-eval	A tool that evaluates Japanese LLMs automatically across multiple datasets. The complete list of supported datasets can be found here (which also includes tasks such as JNLI and JCommonsenseQA from JGLUE).	LLM-jp
JP Language Model Evaluation Harness	A fork by Stability AI of EleutherAI/lm-evaluation-harness. It is a tool for automatically evaluating Japanese LLMs across multiple datasets. The complete list of supported datasets can be found here (which also includes tasks such as JNLI and JCommonsenseQA from JGLUE). There is a detailed summary of the evaluation results by rinna: [rinna] Benchmark of Stability-AI/lm-evaluation-harness	Stability AI
JGLUE	Japanese version of the GLUE benchmark suite, including the MARC-ja, JCoLA, JSTS, JNLI, JSQuAD, and JCommonsenseQA tasks. JCoLA is by the University of Tokyo's Oseki Lab. See here and here (ja only) for further details about each task.	Waseda University Kawahara Lab and Yahoo
JMMLU	A benchmark constructed as a Japanese version of the MMLU Benchmark, consisting of multiple-choice questions from a wide range of academic fields including natural sciences, humanities, and social sciences. In addition to translating the original MMLU, it features newly added problems based on the unique cultural background of Japan (Japan-specific problems).	Waseda University Kawahara Lab

Benchmarks on open-ended generative tasks

	Description	Developer
Japanese MT-bench	The Japanese version of MT-bench asks about multi-turn conversational ability. It includes 80 questions, 10 each, from 8 categories: Writing, Roleplay, Reasoning, Math, Coding, Extraction, STEM, Humanities. Some questions have been modified to fit with Japanese culture during the production of the Japanese version. It also includes a script that performs a 10-level absolute evaluation by GPT-4.	Stability AI
Rakuda Benchmark	Ranking based on model answers to 40 open-ended questions on Japanese geography, history, politics, and society. Uses GPT-4 to judge model outputs pairwise, and then ranks models by fitting a Maximum Likelihood Elo/Bradley-Terry model to GPT-4's preferences.	YuzuAI
ELYZA-tasks-100	Ranking based on model responses to 100 complex and diverse tasks, including tasks testing summarization, correction, abstraction, induction, and other skills. Uses humans to score the model responses and then ranks models based on their mean scores.	ELYZA
Japanese Vicuna QA Benchmark	This is the Japanese version of vicuna-blog-eval, which is the predecessor of MT-Bench. It includes 80 questions on general knowledge, role-playing, common sense, Fermi estimation, counterfactual thinking, coding, mathematics, and writing. It also includes a script for automatic evaluation by GPT-4 (win-rate calculation). The leaderboard can be found here.	Kyoto University Language Media Processing Lab
Tengu-Bench	Includes 120 free-form questions from various categories. Categories of questions: table interpretation, logic puzzles, idea generation, function calling, long document summarization (over a thousand tokens), conversation summarization, long document closed QA (over a thousand tokens), honorifics, project creation, math, translation, extraction, ethical control, cost estimation, Japan, chit-chat, puns, formatting, construction, business, legal judgment, politics, hypothetical questions.	Lightblue

Some performance enhancements have been made to the original Llama model. See here for details. ↩
Details have not been made public but the private dataset includes data from the EleutherAI Polyglot project's Japanese team and from members of Stable Community Japan. ↩
This project conducted evaluation research on using right-to-left generation instead of the usual left-to-right generation, releasing both left-to-right and right-to-left models. ↩
Before conducting Instruction Tuning, a Chat Vector between Llama 3 Instruct and Llama 3 Base is added. ↩ ↩²
After conducting Instruction Tuning, a Chat Vector between Llama 3 Instruct and Llama 3 Base is added. ↩ ↩²
However, if commercial use of KARAKURI LM is desired, direct contact with the developer, KARAKURI Inc., is required. ↩
In Instruction Tuning, because it uses data generated by OpenAI's models, such as GPT-3.5 and GPT-4, for training, there is a possibility that it may violate OpenAI's terms. ↩ ↩² ↩³ ↩⁴ ↩⁵ ↩⁶ ↩⁷ ↩⁸ ↩⁹ ↩¹⁰
Before conducting Instruction Tuning, a Chat Vector between Gemma 2 Instruct and Gemma 2 Base is added. ↩
○: The model is on the HuggingFace Model Hub and can be loaded in with the AutoModel.from_pretrained() command. △: The model is not on the Model Hub but can be loaded in manually with the HuggingFace transformers library. ✕: The model is not directly loadable with HuggingFace. ↩
This project conducted evaluation research on pre-tokenization morphological analysis and released their best performing model, which used Juman++ and BPE. ↩
However, the maximum sequence length has been extended to 2048, and various architectural changes have been made compared to the original BERT. See the HuggingFace repository README for details. ↩
nlp-waseda/roberta-base-japanese and nlp-waseda/roberta-large-japanese trained using a 128 token context length, but nlp-waseda/roberta-large-japanese-seq512 expanded the context length to 512. ↩
Extended to a 1282 context length from the usual 512. ↩
The "small" model trains on Japanese Wikipedia and the Japanese Financial Corpus simultaneously, while the "base" model takes the TohokuUniversityBERT and conducts additional training on the Japanese Financial Corpus. ↩
ManbyoWordPiece conducts a pre-tokenization step using MeCab (IPA+Manbyo dictionaries) and uses WordPiece for subword tokenization, while the SentencePiece model tokenizes text directly using a unigram model. ↩
For details of each model, please refer to Chapter 4 of the authors' paper. Note that the SC-2M-wiki model is strictly not a domain-specific model as it is pre-trained only on Wikipedia. ↩
The classification of embedding models was referenced from Dense Text Retrieval based on Pretrained Language Models: A Survey (Zhao+, 2022). The Bi-Encoder architecture inputs two separate inputs into the model and vectorizes each, using their dot product or cosine similarity as a measure of their proximity. In contrast, the Cross-Encoder architecture inputs the combined inputs into the model to directly compute their proximity internally. Although Cross-Encoders incur higher computational costs, they are often used as rerankers in information extraction due to their ability to compute input proximity more precisely. Among Bi-Encoders, there are types (e.g., ColBERT) that represent the input as multiple vectors (such as one per token) rather than a single vector, hence further classification into Single-representation bi-encoders and Multi-representation bi-encoders. ↩
However, it calls for consideration for use in research and education. Additionally, be aware that some of the licenses for the source models are not Apache 2.0. ↩ ↩² ↩³
