alt Inc. collaborates with AI, Inc., a developer and provider of speech synthesis technology
The project is a demo for service provision using alt's large-scale language processing model LHTM-2 and ChatGPT

alt Inc.(, a Japan based developer of AI Clone and Personal Artificial Intelligence (P.A.I.®️) (Head Office: Minato-ku, Tokyo, Japan; CEO: Kazutaka Yonekura), pleased to announce a business collaboration with AI, Inc. (Headquarters: Bunkyo-ku, Tokyo; President: Shinichi Hiroi; Securities Code: 4388; hereafter "AI"), a developer and provider of high-quality speech synthesis AITalk®. This collaboration aims to build ChatGPT services that can be used by corporations for the purpose of utilizing the large-scale language processing model dialogue AI known as alt' LHTM-2*1 and ChatGPT for AI products.



In September 2021, alt announced the launch of its proprietary large-scale language processing model, LHTM (Large-scale Heuristic Thinking Model)*2. After a year and a half of continuous research and development, we proudly announced LHTM-2 in February 2023.


LHTM-2 utilizes the same number of parameters as OpenAI's GPT-3 and other large-scale language processing models, and while it is capable of generating natural text, it is also designed to be flexible enough to be customized and to internally guide fact-based output. 


The collaboration will combine voice and language data accumulated through AI Inc.'s many years of in-house research and development with alt’s generative AI technology derived from state-of-the-art large-scale language processing models. This demo project will feature automatic dialogue and document creation, automatic article generation, and simultaneous automatic translation into multiple languages in the voices users want to hear.


Through this venture in generative AI, we will continue to accelerate research and development toward the realization of a society in which all people can make the most of their lives without being bound by the constraints of time and space. Our mission is to "free humanity from labor.”
