meta-llama/Llama-3.1-8B Fine-tuned with GRIT and QLoRA

This model is a fine-tuned version of meta-llama/Llama-3.1-8B using the GRIT (Geometric Reprojection Instruction Tuning) algorithm and QLoRA on the openai/gsm8k dataset.

The base model is quantized to 4-bit (NF4) and optimized with Unsloth to enable efficient fine-tuning.
