Generative AI Usage Guidelines for SmileBoom Products
These guidelines supplement the provisions regarding the use of generative AI set forth in Articles 5 (Prohibited Acts) and 6 (Use of Materials) of the EULA for the Company’s products.
Getting Started
SmileBoom Co. Ltd. (hereinafter referred to as “the Company”) does not uniformly prohibit the use of generative AI in game development that uses RPG Developer Bakin, SMILE GAME BUILDER, and other products.
However, when using generative AI, it is important that you take responsibility to verify what you input into generative AI, how the input data is stored and used on the generative AI service, and how you will use the generated content.
This guide describes the situations in which generative AI can be used when creating games with the Company’s products, along with the rules you must follow, using specific examples.
