It's in Unsloth Desktop already. Looks like it's 73GB, so 128GB Mac or Strix Halo etc will work. Exciting!
Download is available, but likely need to wait for an update, I get this which is understandable with the architectural change :
Original error: llama.cpp does not support this GGUF's model architecture ('qwen4exp')
Edit : Saw the pull request, should arrive soon enough https://github.com/ggml-org/llama.cpp/pull/27742
I only see a 1-bit quant posted on unsloth HF and it’s 72.5 GB. Is that what you mean? That’s much bigger than I expected. If you can’t run a 4 bit quant in on Strix Halo it becomes a lot less interesting. https://huggingface.co/unsloth/Qwen3.8-Flash-Next-GGUF
