New Era of Gaming AI Evolution
NVIDIA announced major ACE (Avatar Cloud Engine) platform upgrades at CES 2025, advancing gaming AI from simple dialogue systems to fully autonomous intelligent characters. This technological breakthrough transforms NPCs from scripted characters merely responding to player commands into genuine teammates capable of perceiving environments, formulating plans, and executing actions. Gaming industry leader KRAFTON (PUBG publisher) is first to adopt, launching world’s first Co-Playable Characters (CPC), opening revolutionary chapter for gaming experiences.
NVIDIA ACE Platform Technical Analysis
From Conversation to Autonomous Action
When NVIDIA ACE initially launched in 2023, it primarily focused on conversational AI NPCs, allowing game characters to conduct natural language conversations with players. The 2025 expanded version breaks through this limitation, granting AI characters three core capabilities:
Perception: AI characters can understand game environment states in real-time, including terrain features, enemy/ally positions, resource distribution, time changes. Through computer vision and game engine API integration, AI gains “vision” and “hearing” similar to human players.
Planning: Based on perception information, AI uses decision trees and reinforcement learning algorithms to formulate strategies for achieving goals. For example, in PUBG, AI teammates can assess current equipment, circle positions, enemy threats, deciding whether to engage aggressively or tactically retreat.
Acting: Converts planning into concrete game operations, including movement, aiming, shooting, using items, cooperating with players. AI’s operation style mimics humans, avoiding superhuman reaction speeds, maintaining game balance.
Technical Architecture Components
ACE platform integrates multiple NVIDIA AI technologies:
NeMo Language Model: Handles natural language understanding and generation, allowing AI characters to conduct contextual conversations, respond to player commands, provide tactical advice.
Omniverse Simulation Platform: Trains AI behavior in virtual environments through millions of simulated matches, optimizing decision-making and operational strategies.
RTX GPU Acceleration: Utilizes GeForce RTX and RTX Server GPU AI computing power to execute complex reasoning in real-time, ensuring low latency response.
Audio2Face Technology: Automatically generates facial animations and expressions based on AI voice content, enhancing character expressiveness and immersion.
Human-Level Intelligence and Autonomy
ACE’s goal is creating “human-level” gaming AI, specifically manifested in:
Contextual Understanding: AI doesn’t merely execute preset scripts but truly understands current situations. For example, teammates noticing player has low health and lacks medical supplies will proactively share supplies and provide cover for healing.
Adaptive Learning: Through continuous matches, AI learns player styles and preferences. If players prefer long-range sniping, AI adjusts tactics accordingly, proactively attracting enemy attention.
Social Interaction: Demonstrates emotional reactions and personality traits, cheering after combat victories, showing tension during crisis moments, increasing character credibility and player emotional connection.
KRAFTON’s Co-Playable Characters
