An issue has been reported in the quantized GGUF versions of the Qwen 3.5 language model, created by Unsloth.

Problem Details

Specifically, anomalies were found in the UD_Q4_K_XL quantizations. Subsequently, Unsloth confirmed that all current quantized versions have defects. It is recommended to immediately stop downloading these versions and wait for the release of a corrected version.

The discovery occurred thanks to collaboration among community members, who promptly identified and reported the issue. This demonstrates the importance of cooperation in the development and testing of language models.
