This seems to be the closest thing the board has to an AI-related thread, so I thought I would post this here instead of making a new thread about it.
Vedal is a streamer on Twitch.com, who is also a programmer. He has created his own LLM-based AI, designed to play games and interact with Twitch chat. He named it Neuro Sama. To give "her" a relatable form, he programmed the AI to be able to control a vtuber ("virtual YouTuber") model. Normally in her livestreams, she uses a 2-D model, but recently he worked out programming to allow the AI to drive a 3-D model. Since then she has debuted with her own custom 3-D environments, as well as interacting with open 3-D environments in the shared online space VRChat. In VRChat Neuro can interact with real people who are also using 3-D avatars. Several people who have interacted with Neuro in the 3-D environment, including Vedal himself, have commented on how the 3-D makes Neuro seem much more "real".
Here's a clip from a recent stream done in VRChat, with Neuro interacting with her creator Vedal (his avatar is normally a small, green, cartoon turtle, but in VRChat it looks more like Kermit the Frog.) It really is disturbing how human-like some of her interactions are.
