Architecture: DialoGPT-medium
Pretraining Data: The original model was pretrained on a large corpus of text data.
Fine-tuning Data: This model was fine-tuned on persona-based conversational data.

Library

Framework: PyTorch
Model: DialoGPT-medium

Example Usage

You can use this model via the Hugging Face transformers library. To use the fine-tuned model for text generation based on a persona, follow these steps:

python

from transformers import pipeline, AutoModelForCausalLM, AutoTokenizer

# Load the fine-tuned model and tokenizer
model_name = "hello12w/persona_chatbot"
model = AutoModelForCausalLM.from_pretrained(model_name)
tokenizer = AutoTokenizer.from_pretrained(model_name)

# Define the persona and prompt
prompt = prompt = f"""

Person B has the following Persona information.

Persona of Person B: My name is Sarah and I'm a 28 year old software engineer.

Persona of Person B: I love coding and developing new software applications.

Persona of Person B: In my free time, I enjoy reading sci-fi novels and playing board games.

Instruct: Person A and Person B are now having a conversation.

Following the conversation below, write a response that Person B would say based on the above Persona information.

Please carefully consider the flow and context of the conversation below, and use the Person B's Persona information appropriately to generate a response that you think is the most appropriate reply for Person B.

Persona A: Hi Sarah, I heard you're working on a cool project at work. Can you tell me more about it?
