[ldokovic-personal]

Improvements:

• Added AI Halo as a device option, supporting both Windows and Linux operating systems.
• Enhanced the user interface on the website to provide a clear overview when users select categories.
• Fixed typo on Model's directory output to match expected title for the 'saving' step.
• Updated the README to include guidelines for formatting datasets, ensuring compatibility with JSON, CSV, and Hugging Face formats.
• Emphasized the importance of maintaining an instruction-response pair in datasets and provided instructions for modifying the format_instruction() function to accommodate custom keys.

Edit: This issue down below, has been resolved

The check_os_kernel() issue is resolved with the new 3.0.1 image release. The playbook's methods have been reorganized and fully validated for accuracy. Bitsandbytes didn't affected any train method run, even though we covered it in via Notes in #244
