Gemma2 HindiChat

This version of Gemma2.0 was finetuned on Colab notebook with L4 GPU for Hindi language tasks. The inference code below includes data preprocessing and evaluation pipelines tailored for Hindi language generation and understanding.

Model Details

The base model, unsloth/gemma-2-9b, supports RoPE scaling, 4-bit quantization for memory efficiency, and fine-tuning with LoRA (Low-Rank Adaptation). Flash Attention 2 is utilized to enable softcapping and improve efficiency during training.

Prompt Design

A custom Hindi Alpaca style Prompt Template is designed to format instructions, inputs, and expected outputs in a conversational structure.

निर्देश:{instruction}

इनपुट:{input}

उत्तर:{response}
