Requirements

What your PC
needs.

KM Role Play targets Windows 10 and 11 (64-bit). The rest of the list depends on how you run it — the cards below cover the GPU baseline and how much VRAM each setup needs.

01 Minimum requirements
Graphics NVIDIA discrete GPU
Minimum NVIDIA RTX 3060+ Entry point for the character experience
→
Recommended NVIDIA RTX 4090 24 GB VRAM — runs the full local stack comfortably
VRAM budget · full local ≈ 24 GB
KM Role Play character rendering & motion 6 GB
Local LLM Ollama · Gemma4 12B Q4_K_M GGUF 8.5 GB
Local TTS VoxCPM2 7 GB
Local vector embedding Ollama · BGE GGUF 0.6 GB
Headroom rendering overhead & buffer ≈ 1.9 GB
Flexible — shrink the budget with external services
Switch the LLM to an external API − 8.5 GB
Switch TTS to an external API − 7.0 GB
Switch vector embedding to an external API − 0.6 GB
Minimum execution: 6 GB VRAM. The character alone, with no local model stack. The app still runs — but you give up the full-local experience.
02 How it works on your machine

KM Role Play is local-first: the app lives on your PC, and your characters and conversations are stored there too.

Depending on your setup, you may be able to point KM Role Play at an AI backend you already run, which changes how much your hardware matters.
