Sony's Plan to Create Smart NPCs Using Artificial Intelligence
Sony has filed a new patent designed to improve non-playable characters using artificial intelligence and player behavioral data.
The patent, titled “AI-Adapted Non-Player Character for a Video Game,” describes a system that allows non-playable characters (NPCs) to be personalized and improved based on player behavior. The proposed system collects real-time gameplay data and uses it to adjust the behavior, design, and reactions of enemies and other in-game characters accordingly.
According to IGN, unlike NVIDIA's ACE technology, which focuses on generating dialogue using large language models, Sony's proposed system could adapt the way bosses fight to suit each player's tactics. One of the main goals of the technology is to reduce the cost and time required for manual programming and extensive scripting.
Sony's official patent describes the challenges of current game development methods as follows:
“The development of such believable NPCs is difficult due to the limitations of the modern development of games and often relies on extensive scriptwriting and programming. In addition, the development of NPCs usually depends on complex systems and extensive resources for tracking, mobilization, and evolution of NPC behaviors. In a typical development environment, the management of the NPC often has expensive and efficient rendering engines and scalable systems to support virtual environments with increasing detail and real interactions.”
The document then explains how the proposed technology could help overcome some of these challenges:
“The techniques described here overcome by providing an NPC-compatible with artificial intelligence challenges and other. Using the techniques described here, video game systems can be improved.”
Sony also describes the potential benefits of using player behavior to influence how NPCs react:
“In addition, using the techniques described in this document, realistic NPCs that act or respond to the behaviors displayed by video game players can seamlessly integrate with video game systems and content without the need for extensive scripting and heavy hardware resources, thereby improving game systems.”
The gaming industry has already experimented with similar technologies. For example, inZOI has used language models to create more dynamic interactions between characters and players. Using similar systems in games such as Elden Ring could potentially allow combat patterns to continuously evolve according to the player's fighting style.
However, storing and processing player information through cloud-based systems could also raise concerns about data security and how that information may be used.
The filing of a patent does not guarantee that Sony will eventually implement this technology on PlayStation 5 or its next-generation consoles. In recent months, Sony has also filed patents covering other concepts, including AI-assisted console troubleshooting and a controller with NFC card-reading capabilities.
