Gamers get AI co-players with next-level strategic intelligence, thanks to NVIDIA

AI companions are taking a dramatic leap forward in gaming, with NVIDIA and Krafton introducing the first "co-playable character" (CPC) for PlayerUnknown's Battlegrounds. This AI teammate, announced at CES 2025 and dubbed PUBG Ally, goes beyond traditional scripted behaviors to communicate naturally with players, share strategic advice and adapt to dynamic battlefield conditions. Unlike conventional AI co-players that follow rigid programming, these companions can independently gather resources, operate vehicles and engage in combat while using game-specific terminology that makes interactions feel authentic.

The technology powering the co-playable characters is NVIDIA ACE. It uses small language models optimized for quick decision-making so AI co-players can process their environment, plan actions and respond to changing situations much like human players would. The innovation stems from a strategic collaboration between Krafton's Deep Learning Division, established in 2022, and NVIDIA's expertise in AI technology.

The way PUBG Ally balances autonomy with collaboration — acting independently but remaining responsive to player input and team needs — reflects a shift in human-AI interaction in other fields. AI systems aren't simply replacing human tasks but rather augmenting human capabilities, whether assisting physicians in diagnosis while adapting to unique patient cases or, in software development, understanding project context and suggesting coding solutions while still working within a developer's overall vision and strategy.
