Sony Describes AI Enemies That Could Adapt to a Player’s Style Mid-Fight

Sony Interactive Entertainment has developed a concept for a system that would let NPCs and bosses change their behavior based on a specific player’s actions. The AI could factor in the weapons used, attack accuracy, dodges, parries, healing and the results of previous encounters, then generate new behavior for the characters.

The technology is described in a patent application titled AI-Adapted Non-Player Character for Video Game System. It was filed on March 31, 2025, and published in the US on October 1, 2026 under number US 2026/0295429 A1.

Importantly, this is still just a patent application, not an announced PlayStation feature. Sony has not named any games where it plans to use the system, nor has it said anything about bringing it to the PS5 or future consoles.

The AI could analyze exactly how a person plays

The system would collect detailed statistics on a player’s encounters with NPCs. The document lists hit accuracy, weapons used, damage dealt and taken, critical hits, fight duration and the use of healing items.

It could also take into account dodges, blocks and parries, how often they succeed, positioning, reaction time and the number of attempts it takes to beat a boss.

That data is then fed to a machine learning model, which creates modified content for the NPC. This could affect not only combat tactics but also the character’s movements, dialogue, appearance and social behavior.

Sony even gives more radical examples: the system could potentially change an NPC’s role, turning it into an enemy, ally, merchant, quest character or boss. It also describes reinforcements appearing in place of enemies already defeated.

Changes could be introduced mid-game

One of the most interesting scenarios suggests the generated changes could be added directly during an active game session, without waiting for a traditional game update.

Still, saying “the enemy will learn to counter every move a player makes” would be too strong. The patent does not say that a few successful parries will automatically make a boss immediately abandon a specific attack. Instead, that kind of statistic becomes one of the model’s input parameters, and the model then determines the behavior changes.

What’s more, the data could be collected from more than one person. The application covers options for training on encounters from many players and gaming devices.

Sony also sees this approach as a way to reduce the amount of manual work that goes into complex NPC scripts. In theory, developers could set general rules and constraints, while the model generates part of the behavioral variation.

It’s still unclear whether the concept will ever make it into real games. Big companies regularly patent technologies that never turn into commercial products. So for now, the work is best seen as one of Sony’s research directions in adaptive game AI, not as a confirmed feature of future PlayStation games.
