LINE Revolutionizes Japanese AI: Unleashing Open-Source Language Models for Comprehensive Access

Recognized as one of the leading tech giants in Japan, LINE has embarked on a transformative journey since November 2020. Their mission – to develop a large-scale language model specifically tailored for the intricate nuances of the Japanese language.

In a noteworthy development, LINE’s Massive Language Model (LM) unit recently announced the release of its “Japanese-large-lm” language models as open-source software (OSS). This monumental step serves not just as a triumph of technological advancement, but a milestone in LINE’s relentless pursuit of innovation and accessibility in digital communication.

The Japanese-large-lm project comprises of two mammoth language models – a 3.6 billion parameter model and a comparatively smaller, but equally effective 1.7 billion parameter model. Developed with a precision-oriented approach, these models were trained to deliver accuracy and efficiency in language processing tasks. LINE believes that the open-source release of these models will not only boost innovation within the tech community but also invite potential collaborations and improvements for these language models.

Keeping user-friendly access at the forefront, these models are conveniently available on the HuggingFace Hub and the renowned Transformers library. Furthermore, they are accompanied with the generous Apache License 2.0, enabling users from across the globe to utilize, adapt, and even distribute these models in accordance to their needs.

The development of these models was no small feat. LINE utilized a substantial and high-quality training dataset, ensuring a broad spectrum of data diversity. To maintain the quality and relevance of the dataset, a stringent filtering process was incorporated using the HijojiChar OSS library. This meticulous attitude towards dataset refinement serves as a testament to LINE’s unwavering commitment towards optimal performance in its AI initiatives.

In terms of model training, LINE broke new ground by implementing 3D Parallelism and Activation Checkpointing. These state-of-the-art techniques allowed for efficient utilization of GPU memory and computational resources, ensuring a streamlined training process. For instance, despite its colossal number of parameters, the 1.7 billion model demonstrated remarkable efficiency in language tasks without compromising on accuracy or speed.

While on a similar trajectory of language modeling, it is crucial to note that the development of the Japanese-large-lm models is separate from HyperCLOVA, another laudable AI initiative within LINE. Unlike HyperCLOVA, the Japanese-large-lm models form part of an independent developmental line steered by a dedicated department.

The release of these large-scale language models emphatically echoes LINE’s unwavering commitment towards pioneering advancement in the field of AI and language models, particularly for the Japanese language. As we await future developments from LINE, we can only anticipate that the AI landscape will continue to evolve, brimming with cutting-edge innovation and enhanced accessibility.

We encourage you to further explore LINE’s groundbreaking language models or even contribute to their open-source software initiative. After all, innovation becomes more meaningful when we embark on the journey together, traversing the paths less taken, towards a future powered by AI.
