Write your own LOTR story with LORA BLOOM-3B

LOTR Storyteller: the AI of Sauron 🧙

Write your own Lord Of The Rings story!

Version 1.1 / 23 May 2023

Description

In this project, we have designed an AI assistant that completes your stories in the LOTR style. During the development of the app, we have:

• Extracted the text from the official book,
• Prepared the dataset,
• Trained BLOOM-3B using Low-Rank-Adapters,
• Deployed the model on Inference Endpoints from Hugging Face,
• Built the app using Streamlit,
• Deployed it into Streamlit cloud.

Notes: regarding the cost of deploying a model this large, the app is not available for testing

⚙️ Model fine-tuning [code]

This LLM is fine-tuned on Bloom-3B with texts extracted from the book "The Lord of the Rings".

🚀 Model deployment and app [code]

The model is deployed on Inference Endpoints from Hugging Face, and the applicaiton is built and deployed on Streamlit.

Load the model

from transformers import AutoModelForCausalLM, AutoTokenizer
from peft import PeftConfig, PeftModel

# Import the model
config = PeftConfig.from_pretrained("JeremyArancio/llm-tolkien")
model = AutoModelForCausalLM.from_pretrained(config.base_model_name_or_path, return_dict=True, load_in_8bit=True, device_map='auto')
tokenizer = AutoTokenizer.from_pretrained(config.base_model_name_or_path)
# Load the Lora model
model = PeftModel.from_pretrained(model, "JeremyArancio/llm-tolkien")

Run the model

prompt = "The hobbits were so suprised seeing their friend"

inputs = tokenizer(prompt, return_tensors="pt")
tokens = model.generate(
    **inputs,
    max_new_tokens=100,
    temperature=1,
    eos_token_id=tokenizer.eos_token_id,
    early_stopping=True
)

# The hobbits were so suprised seeing their friend again that they did not 
# speak. Aragorn looked at them, and then he turned to the others.</s>
