[BUG] Default Model On LoRaTrainingExample won't install.

[jacobwoods45]

Describe the bug
The default model in LoRaTrainingExample hangs indefinitely.

To Reproduce
Start the application LoRaTrainingExample, observe by simply starting the application.
Include code snippet

private let modelConfiguration = LLMRegistry.mistral7B4bit

Expected behavior
Model should download as expected and not hang. You can observe expected model by changing model.

Desktop:

• OS Version: 26.1 (25B78)
• Device: Macbook Pro M3 Pro
• Version: Current Version

Additional context
Quickfix: just change the default model, I suspect the model that is default is just no longer supported by Hugging Face.

The default download of that mistal model is about 4.08 GB; we can probably use a smaller model for it
