Researchers have released new GGUF quantized models for Qwen3.8-27B, utilizing GSQ (Gumbel-Softmax Quantization) and RCO (Riemannian Constrained Optimization) techniques. These methods aim to improve model quality and accuracy at lower bitrates (2.5 to 3.0 bpw) while maintaining the same file sizes as previous quantizations. The new models reportedly match or exceed existing GGUF quantizations for Qwen3.8-27B in terms of accuracy on benchmarks like AIME25, GPQA-Diamond, and LiveCodeBench. AI
IMPACT Offers improved accuracy for quantized models, potentially enabling more efficient deployment of large language models on consumer hardware.
