OpenAI has given Japanese companies early access to a special version of GPT-4 optimized for the Japanese language. This model provides improved performance when working with Japanese text and is up to 3 times faster than GPT-4 Turbo. The company also plans to release a model API in the coming months.

According to OpenAI, Japanese companies are actively using ChatGPT, and primarily ChatGPT Enterprise. We are talking about companies such as Daikin, Rakuten and Toyota Connected, which use AI to automate complex business processes, help with data analysis and streamline internal reporting. ChatGPT is also in demand among city administrations: for example, the city of Yokosuka uses AI to improve the efficiency of providing public services. Over the past year, the city has made ChatGPT available to nearly all administrative employees, and 80% reported increased productivity.

Amid active promotion of its services in Japan, OpenAI announced the opening of its first office in the country. The division was headed by Tadao Nagasaki, former president of Amazon Web Services in Japan.

"We hope to spend a lot more time in the country, interact with great talent and create something great for the Japanese people," Altman previously said. He emphasized that OpenAI will work to make its models more attractive to the Japanese language and Japanese culture.
