A comparison of various quantization methods for the Qwen3.6 27B model reveals that GGUF formats generally offer the best quality-to-size trade-offs. These GGUF models, which do not quantize activations, showed lower KL divergence compared to other formats like NVFP4, AWQ, AutoRound, and FP8. The study found that vLLM quantizations can vary significantly in their effectiveness, with some performing notably worse than others of similar or even smaller sizes. AI
IMPACT GGUF formats offer superior quality-to-size ratios for local LLM deployment, potentially improving performance on consumer hardware.
