Tadao Nagasaki has been appointed President of OpenAI Japan to lead the company's business in Japan. He will oversee commercial activities, market engagement, and building the local team, leading integration with the local community.
As a technical achievement, OpenAI unveiled a custom GPT-4 model specialized for Japanese. This model offers improved performance in Japanese translation and summarization, and provides up to 3x faster speed and greater cost efficiency compared to the existing model.
- The English-learning app Speak used this to increase tutor explanation speed by 2.8x and cut token costs by 47%.
- This model is expected to be widely released via the API in the coming months.
Major companies such as Daikin, Rakuten, and TOYOTA Connected have already adopted ChatGPT Enterprise for work automation and data analysis. Local governments such as Yokosuka City are also using the technology to improve the efficiency of public services.
