Remeber this model is for illustration and knowlwdge Purpose. I have only used online freely available materials in whole process.
Model Details
This Model is Trained on Custum data related to Sales interactive conversations as Array of objects having Instruction and Response as Keys. -Parameters: ~8 Billion -Quantization: 4 Bit (Q-LORA)
Model Description
This is the model card of a 馃 transformers model that has been pushed on the Hub.
- Trained by: [vakodiya] [Viru Akodiya]
- Model type: [Text-Generation]
- License: [apache-2.0]
- Finetuned from model: [meta-llama/Llama-3.1-8B-Instruct]
Training Data
Training Data is specifically generated by me to train to my use case. It consits of Just 500 examples, so to increase dataset size, duplicated the original data and makes it 1000.
Training Hyperparameters
- Hardware Type: [Kaggle's GPU T4X2]
- Time used: [37 Minutes]
- Cloud Provider: [Kaggle]
INFERENCE (It will need GPU)

Remember to Customize your own data with at least 1000 examples.
Data_examples = [{"instruction":"Who has taken oath as Prime minister of India in 2024", "response":" Shri Narendra Modi has taken oath as Prime minister of india on 9th June 2024. He is now become prime minister having 3 consecutive terms."},

Process data to stringify only the text
field
processed_data = []
for example in Data_examples :
processed_data.append({'text':f"{example['instruction']} \n {example['response']}"})
# Create a Dataset from the list of dictionaries
dataset = Dataset.from_list(processed_data)
# Split into train and test Data sets
dataset = dataset.train_test_split(test_size=0.01)
# Access train and test splits
train_dataset = dataset['train']
test_dataset = dataset['test']
Firstly add model to Kaggle notebook navigating to Add Input and Add LLama3.1 8 B in out Notebook

Save model in Notebook (in output_directory)
trainer.save_model()
Merge LoRA with the base model and save the merged model
merged_model = trainer.model.merge_and_unload()
merged_model.save_pretrained("merged_model",safe_serialization=True)
tokenizer.save_pretrained("merged_model")
push merged model to the HuggingFace-hub (You must have logged in already)
