🙌 Thank you, Ollama Desktop Team!

First off, I want to express my appreciation for the incredible work you're doing with Ollama Desktop. It's exciting to see how accessible and powerful local model execution has become thanks to your platform.

I'm reporting an issue I encountered while attempting to run a GGUF model. I hope this helps improve compatibility and user experience for others working with similar setups.

The error occurs when trying to run the model hf.co/microsoft/bitnet-b1.58-2B-4T-gguf using Ollama Desktop.
