A highly efficient 2-bit quantized version of the Qwen3.8-27B large language model designed to run on consumer-grade GPUs. It enables a 27B parameter model to fit within approximately 10.15 GB of VRAM, allowing for large context windows on hardware like the RTX 3090 or 4090.
Highlights
Uses mixed 2/3-bit quantization to achieve a small 10.15 GB weight footprint
Optimized to fit a 27B model and 64k context on a single 24 GB consumer GPU
Maintains competitive performance in commonsense reasoning and coding compared to FP8 references
Requires a specialized SGLang-based runtime (escha-runtime-qwen3dense) for deployment
