peer-model-0.04

Fine-Tuned Llama-3.1-8B-Instruct with QLoRA

This model was fine-tuned on anphiriel/peer-dataset-0.04 using QLoRA with 4-bit quantization.

• Base Model: meta-llama/Llama-3.1-8B-Instruct
• Training Data Size: 16256 examples # Use actual dataset size
• Training Epochs: 10 # Use value from args
• Learning Rate: 0.0002 # Use value from args
• Marker: <|eot_id|>
• LoRA Config: r=16, alpha=32, dropout=0.05
• Quantization: 4-bit NF4, bfloat16 compute
• Effective Batch Size: 16
• Evaluation Metric for Best Model: eval_loss
• Early Stopping Patience: 3

This model is intended for use as a chatbot/sales assistant. It was trained on data formatted using the Llama-3.1 chat template.
