Summary
A discussion on r/LocalLLaMA warns that Nvidia's NVFP4 quantization for Qwen3.5-397 might lead to a loss of model intelligence due to high KLD divergence. Users experiencing performance issues are advised to switch to alternative quantizations, such as Sehyo's NVFP4 or Quantrio's AWQ, for better accuracy. This problem is reportedly less visible in larger models.
