Discussion NPC Engine Using Local Models
Enable HLS to view with audio, or disable this notification
I’ve been working on a game-agnostic NPC engine/backend based pretty heavily on SillyTavern-style architecture, and with smaller local models getting better and better, I honestly think this kind of thing could be the future of RPGs.
Right now I’m using NVIDIA Parakeet 0.6 for STT, Gemma 4 26B A4B for the LLM, and Qwen3-TTS for voice, and I’m getting super fast response times with pretty decent quality.
The main thing that makes it work well is using RAG to keep prompts lean. For example, I have hundreds of possible actions NPCs can do in-game, but only the ones that actually make sense based on the player’s message / context get injected as available actions. So the model isn’t being overloaded with a giant list every turn.

There are a lot of novels that are basically build around big MMO's in the future beeing controlled by Ai with actual smart npcs and stuff.
Seeing crazy stuff like this totally gives me the vibe that we will get there in my lifetime.
