Japan’s biggest gaming and anime companies fight back against OpenAI’s Sora 2

Major Japanese entertainment firms are protesting OpenAI’s Sora 2 video AI, formally asking them to cease using Japanese content for training without proper authorization.

According to Automaton, CODA, an industry organization, has formally asked OpenAI to stop using Japanese anime, manga, and video game material without permission in the development of Sora 2.

CODA, which works with major rights holders like Aniplex, Bandai Namco, Studio Ghibli, Square Enix, and Kadokawa, claims that the visuals in Sora 2 are very similar to existing Japanese creative works. They believe this suggests those works were used to train the AI model without permission.

Japanese publishers demand OpenAI stop using their content

So, I was reading about this case, and CODA is basically saying that in Japan, if you want to use someone’s work to train AI, you need their permission first. They’re also pushing back against the idea of just removing content after someone complains about it being used – they think that doesn’t protect creators enough, and companies should get permission upfront to avoid any copyright issues.

The Conference on Digital Art (CODA) has requested that OpenAI provide clear answers to any copyright questions from its publishing members. Earlier this month, government officials cautioned OpenAI about AI-created anime videos appearing online, urging them to respect and follow copyright laws.

I tried out the AI model Sora 2 using classic anime, and the results are amazing – it’s almost unbelievable! I can already imagine all the fan-made videos and parodies people will create. Sora 2 is a real breakthrough for AI-generated anime.

Government officials recognize anime and manga as important cultural treasures that need safeguarding as new technologies like AI develop. OpenAI has stated they intend to empower artists with greater control over their creations and are considering ways to share revenue with them in the future.

Japanese copyright owners argue that these proposals don’t deal with how copyrighted works are used when first creating the AI models.
