Nvidia’s AI NPCs Fear Me, the Dreaded Ramen Bounty Hunter

Jan 12, 2024 - gizmodo.com
The article discusses a demo of Nvidia's AI NPC (Non-Player Character) technology, developed in collaboration with conversational AI startup Convai. The demo, set in a cyberpunk city, features AI characters like Kai, Jin, and Nova, who interact with each other and the player. The AI's speech and animations are facilitated by Nvidia's Avatar Cloud Engine (ACE), Audio2Face, Riva ASR systems, OpenAI’s GPT-3.5 Turbo LLM, and ElevenLab’s voice generation. However, the article criticizes the AI characters for their dry and emotionless dialogue.

The article also questions the scalability of Convai’s AI NPCs, as they currently operate off the cloud, requiring powerful servers. Nvidia aims to develop a hybrid system where some models run on the computer, but the article suggests this is a big "if" considering the size of advanced AI like GPT-4. The article also criticizes the AI NPCs for their lack of character and emotion, comparing them unfavorably to the NPCs in games like Cyberpunk 2077.

Key takeaways:

  • Nvidia and Convai have collaborated on a demo showcasing AI NPCs (Non-Player Characters) in a cyberpunk city setting, using Nvidia’s Avatar Cloud Engine (ACE) for semi-real-time interactions.
  • The demo characters' dialogue and behavior are currently quite stilted and dry, indicating that the language models powering these avatars will heavily influence their individual 'character'.
  • Despite the current limitations, major publishers like NetEase, Tencent, and Ubisoft have expressed interest in using ACE to create AI avatars.
  • There are concerns about the scalability of these AI NPCs, as they currently require powerful servers to run and any game using them would need to be online-only.
