Generative AI has moved beyond experimental demos and is now part of day-to-day workflows across parts of the games industry. Two major 2026 surveys show that adoption is already significant, although the numbers vary dramatically depending on region and job role. How many game developers actually use generative AI? And what are they using these tools for?

Generative AI Usage Reaches 85.8% Among Surveyed Developers in Japan

A new survey published by Japan's Computer Entertainment Supplier's Association found that 85.8% of surveyed game developers use generative AI at work. Around 63% said they use it regularly, while another 22.8% reported occasional use. The survey received 1,349 valid responses.

That figure should not be interpreted as the global adoption rate for game development. CESA's research focuses on the Japanese games industry and this was the organization's first dedicated survey of generative AI usage. As a result, claims comparing the 85.8% figure directly with previous CESA data should be treated carefully.

Global Industry Surveys Show a Different Picture

The 2026 State of the Game Industry report from GDC found that 36% of game industry professionals use generative AI as part of their jobs. Usage among people working directly at game studios was lower at 30%, while respondents in publishing, support, marketing and PR reported significantly higher adoption.

The GDC survey included more than 2,300 industry professionals, but its respondents were disproportionately based in North America and Western Europe. That means neither the GDC nor CESA figure should be treated as a universal global adoption rate. The surveys cover different populations and use different methodologies.

The contrast still illustrates how differently generative AI is being adopted across parts of the industry. Japan's development community reports particularly high usage, while the broader GDC sample shows a much more mixed picture.

What Are Game Developers Using AI For?

Among GDC respondents who use generative AI, research and brainstorming was the most common use case at 81%. Code assistance and everyday work such as writing emails both reached 47%, while 35% reported using AI for prototyping. Asset generation was considerably lower at 19%.

Higher adoption does not necessarily mean developers are more comfortable with the technology. In GDC's survey, 52% of game industry professionals said generative AI is having a negative impact on the industry, even as more workers continue to use it in their jobs. Do you think generative AI should remain a supporting tool in game development, or become a larger part of production?
