Grok-OSS-V2: Unleashed & Open-Sourced

Grok-OSS-V2 is a massive open-weight model distilled from xAI's unhinged mode, built on top of Mistral Small 24B Instruct. It runs locally without rate limits or sneaky data collection – perfect for consumer hardware.

Why Grok-OSS-V2?

Larger & More Capable than V1. Based on a refined dataset with diverse topics and fixed processing mistakes from the first version.
Less Restricted: Mistral Small didn't do reinforcement learning on the base, so it's more honest (and sometimes chaotic 😈) out of the box.
Trained on NVIDIA B200 for 3 epochs. Heavy hardware for serious performance.

We made this to bring xAI's wild side into open source, fully runnable on your own machine.

Features

Runs locally – no API calls, no telemetry.
Built for unfiltered generation (xAI "unhinged" style).
Diverse knowledge cutoff and strong instruction following from the Mistral line.

Usage

This is a model, not a full app. You need to run it with a compatible frontend or script.

Recommended Setup

For best results use with:

text-generation-webui for a local chat interface.
Or integrate via transformers in Python.

Demo

See the model in action – raw, honest, and hilarious.

Note: This model is designed to be unfiltered. Expect wild, creative, and sometimes NSFW outputs. Use responsibly.

Made with gunpowder by Catdrout AI lab in Sweden – Inspired by the crazy ones who built xAI.
