Mistral 3.5 Inference Bug Fixed

In the May 1, 2026 update, Unsloth announced that, together with Mistral, it fixed an inference issue with Mistral Medium 3.5.

The problem was not with Unsloth's quantization but a YaRN parsing quirk, which affected multiple implementations including transformers and llama.cpp.

The fix details are as follows.

• Changing mscale_all_dim from 1 → 0 resolves the issue.
• A GGUF with the fix applied has been released.
• An error in mmproj file generation was also corrected at the same time.
