amusktweewt/tiny-model-700M-chat

This is a general-purpose transformer-based language model tailored for conversational tasks, story generation, and code-related interactions. It builds upon earlier models in the "tiny" series with increased model size, improved attention efficiency, and optimized training setup.

It is more than twice as smart as the 500M model, with a significantly better user experience. It knows more facts and is the first model in this series capable of performing basic arithmetic.

How to Get Started

import torch
from transformers import pipeline, set_seed

# Set up the text-generation pipeline
model_name = "amusktweewt/tiny-model-700M-chat"
chatbot = pipeline(
    "text-generation",
    model=model_name,
    device=0 if torch.cuda.is_available() else -1
)

# Ensure that bos_token and eos_token are explicitly set as strings
chatbot.tokenizer.bos_token = "<sos>"
chatbot.tokenizer.eos_token = "<|endoftext|>"

# Set seed for reproducibility (optional)
set_seed(42)

print("Chatbot is ready! Type 'exit' to end the conversation.")

# Initialize the conversation history
conversation_history = []

conversation_history.append({"role": "system", "content": "You are a highly intelligent and helpful AI assistant named Tiny Chat, developed by amusktweewt. Always refer to yourself like that. Your responses should be clear, concise, and accurate. Always prioritize user needs, provide well-structured answers, and maintain a friendly yet professional tone. Adapt to the user's preferences and communication style. When needed, ask clarifying questions to ensure the best response. Be honest about limitations and avoid making assumptions. Keep interactions engaging, informative, and efficient."})

while True:
    user_input = input("You: ").strip()
    if user_input.lower() == "exit":
        print("Exiting chat. Goodbye!")
        break

    # Append user message to the conversation history
    conversation_history.append({"role": "user", "content": user_input})

    # Prepare the messages with the conversation history and an empty assistant turn
    messages = conversation_history + [{"role": "assistant", "content": ""}]

    # Use the tokenizer's apply_chat_template() method to format the prompt.
    prompt = chatbot.tokenizer.apply_chat_template(messages, tokenize=False)

    # Generate text using the formatted prompt.
    response = chatbot(
        prompt,
        do_sample=True,
        max_new_tokens=512,
        top_k=50,
        temperature=0.6,
        num_return_sequences=1,
        repetition_penalty=1.1,
        pad_token_id=chatbot.tokenizer.eos_token_id,
        min_new_tokens=20
    )

    # The returned 'generated_text' includes the prompt plus the generation.
    full_text = response[0]["generated_text"]
    # Extract the assistant's response by removing the prompt portion.
    bot_response = full_text[len(prompt):].strip()
    print(f"Bot: {bot_response}")
