Download · SID 6.7.5-beta

Three things. One simple local setup.

SoloRoleplayer// needs the frontend, a model server, and the model. Anti-H 2.0 is the optional upgrade. The app, the LoRA and the model are all available now.

1 · The frontend

SoloRoleplayer//

The offline roleplay frontend you play in.

Download for Windows Mac: run from source

Windows will say "Windows protected your PC" because the installer is not signed with a paid certificate yet: choose More info, then Run anyway. The release page lists file fingerprints and VirusTotal scan links (scanned on VirusTotal; links are on the release page). Built on a Mac and verified under Wine; not yet run on a real Windows PC.

2 · A model server

Bring your own

Any OpenAI-compatible local server: LM Studio, llama.cpp, KoboldCPP, Ollama, or Cute LM on a Mac later.

3 · The model

Mistral Nemo 2407 (abliterated)

Open on Hugging Face

Optional upgrade

Anti-H 2.0, the LoRA for better roleplay discipline.

Our LoRA for Mistral Nemo keeps the companion in its own lane and the writing clean. In a four-run benchmark it cut head-hopping in what the player sees from 24% of replies to 6%, with real costs: shorter replies and more repeated phrases. The weak spots are published with it.

What it is built for

Your computer, your model, your story.

ModelMistral Nemo 12B in a 4-bit build

Memory16 GB of RAM or more

On 16 GB of RAMOn 16 GB of RAM the model may run RAM hot and stop inside of SoloRoleplayer even if the LLM server keeps running. You do not have to exit your session, just restart the LLM server (Ollama, Cute LM, etc.) and continue from the error once it's live again. It's a known limitation of smaller RAM allotments but from my testing (On a Mac) has been safe to run in multi-hour sessions. On average 2 restarts for every few hours of play.
