Description:
Unsloth downloads models from HuggingFace using all lowercase names (e.g., meta-llama-3-70b-instruct), while Hugging Face Transformers uses the original casing (e.g., Meta-Llama-3-70B-Instruct).

Issue:

• This causes the same model to be downloaded twice.
• One version by Unsloth, another by AutoModel or other HF tools.
