The Emergence of Shisa V2 405B

Shisa V2 405B, built on the Llama3.1 architecture, is celebrated as the most powerful open-source language model ever trained in Japan. This model excels not only in Japanese tasks but also maintains robust English processing capabilities, showcasing its exceptional performance in bilingual applications.

Performance Highlights

• Benchmark Testing: Shisa V2 405B has outperformed both GPT-4 and GPT-4Turbo in various Japanese benchmark tests. It stands toe-to-toe with the latest models, including GPT-4o and DeepSeek-V3, particularly in tasks related to the Japanese language.
• Significance: This achievement underscores the rise of local AI laboratories in Japan, opening new avenues for Japanese AI applications on a global scale.

Innovations in Japanese Language Optimization

Shisa.AI has strategically shifted its focus towards optimizing Japanese language models. The Shisa V2 series has moved away from costly pre-training and tokenizer expansions, instead honing in on post-training processes that leverage synthetic data to enhance model performance.

Key Features of the Shisa V2 Series

• Core Dataset: The ultra-orca-boros-en-ja-v1 dataset, which has undergone rigorous filtering and resampling, is recognized as one of the most powerful bilingual datasets available. This resource is now freely accessible under the Apache 2.0 license, providing invaluable support to developers worldwide.
• Model Variants: The Shisa V2 series offers a range of models from 7B to 405B parameters, catering to diverse needs from lightweight devices to high-performance computing environments.

Versatility Across Applications

The Shisa V2 models demonstrate remarkable versatility across various tasks, including:

• Japanese Grammar: Enhanced capabilities in understanding and generating grammatically correct sentences.
• Role-Playing: Superior performance in role-playing scenarios, as evidenced by the shisa-jp-rp-bench benchmarks.
• Translation: Exceptional results in translation tasks, particularly in the shisa-jp-tl-bench evaluations.

Notably, Shisa V2 405B incorporates a small amount of Korean and Traditional Chinese data, further enriching its multilingual capabilities and expanding its applicability in cross-language scenarios.

Driving Global AI Innovation Through Open Source

Shisa.AI's commitment to open-source principles not only elevates the performance of Japanese AI but also fosters innovation within the global AI community. The training logs for the Shisa V2 series are publicly available on the Weights and Biases platform, showcasing the development process that utilized a 4-node H100 cluster on AWS Sagemaker, combined with cutting-edge technologies like Axolotl, DeepSpeed, and Liger Kernel.

Future Developments

Shisa.AI plans to release its Japanese-specific benchmark testing tools, facilitating research and evaluation of large language models in Japanese. This initiative aims to provide further support to developers and researchers in the field.

Japan's Competitive Edge in AI

The success of Shisa.AI illustrates that even smaller AI laboratories can carve out a niche in the global AI arena. The release of open-source models and datasets significantly bolsters the accessibility of Japanese AI applications. As Shisa.AI continues to refine its models and resources, Japan's position in the global AI landscape is poised for further strengthening.
