Mag-Mell-R1-Uncensored-21B-GGUF

🧠 Model Overview

Mag-Mell-R1-Uncensored-21B-GGUF is a quantized version of Mag-Mell-R1-Uncensored-21B, optimized for efficient inference with reduced memory usage and faster runtime while preserving as much of the original model quality as possible.

This repository provides multiple quantized variants suitable for:

• Local inference
• Low-VRAM GPUs
• CPU-only environments
