As our business grows internationally, we are expanding into Asia with a new office in Tokyo, Japan. We are committed to working with the Japanese government, local businesses and research institutions to develop secure AI tools that serve Japan's unique needs and unlock new opportunities. We chose Tokyo as our first Asian office because of its global leadership in technology, culture of service and community that embraces innovation.

“We are excited to be in Japan, which has a rich history of bringing people and technology together to do more. We believe AI will accelerate work by empowering people to be more creative and productive, while providing broad value to current and new industries yet to be imagined.” – Sam Altman, CEO of OpenAI

To lead our efforts in Japan and ensure we are deeply integrated into the local community, we welcome Tadao Nagasaki as our new President of OpenAI Japan. Mr. Nagasaki will lead our commercial and market engagement efforts and help build our local team to advance global business, go-to-market, communications, operations and other functions in serving Japan.

As the first step in our long-term commitment to the region, we're providing local businesses with early access to a GPT-4 custom model specifically optimized for the Japanese language. This custom model offers improved performance in translating and summarizing Japanese text, is cost-effective and runs up to 3 times faster than its predecessor. Speak, Japan's top English learning app, gets 2.8x faster Japanese teacher explanations when users make mistakes with a 47% token price reduction, unlocking higher-quality teacher feedback in more places and with higher limits per user. We plan to release the custom model more widely in the API in the coming months.
