Getting Started with the Uncensored Qwen2.5-14B-Instruct-abliterated-v2 Model

Welcome to your journey into using the latest and most robust version of the Qwen model! This guide will help you understand how to utilize the uncensored version of Qwen2.5-14B-Instruct-abliterated-v2 and make the most out of its advanced text-generation capabilities.

Understanding Qwen2.5-14B-Instruct-abliterated-v2

The Qwen2.5-14B-Instruct-abliterated-v2 model is an advanced AI assistant created by Alibaba Cloud, designed for text generation without censorship constraints. It incorporates the innovative technique known as abliteration, enhancing its functionality over the previous version. Special kudos to @FailSpy for his original contributions!

How to Use the Model

You’ll need to load the model using the Hugging Face transformers library. The following steps will guide you through the process:

• Ensure you have the transformers library installed.
• Load the model and tokenizer.
• Set up an initial conversation context.
• Start a conversation loop for interaction.

Code Walkthrough

The provided code essentially serves as a blueprint for creating an interactive chat with the Qwen AI. Let’s use an analogy to make this clearer: think of the code as setting up a restaurant where the AI (Qwen) is the chef, waiting to take orders (user inputs) and serve meals (responses).

• First, you gather your ingredients (load the model and tokenizer).
• Then, you set the table (initialize the conversation context).
• Once the service starts, customers (users) give their orders (input) and, based on those orders, the chef prepares meals (generates responses) using his skills and immense recipe book (model’s capabilities).
• The cycle continues until the customer decides to leave or needs a reset (exit or clean commands).

python
from transformers import AutoModelForCausalLM, AutoTokenizer

# Load the model and tokenizer
model_name = "huihui-ai/Qwen2.5-14B-Instruct-abliterated-v2"
model = AutoModelForCausalLM.from_pretrained(model_name, torch_dtype="auto", device_map="auto")
tokenizer = AutoTokenizer.from_pretrained(model_name)

# Initialize conversation context
initial_messages = [{"role": "system", "content": "You are Qwen, created by Alibaba Cloud. You are a helpful assistant."}]
messages = initial_messages.copy()  # Copy the initial conversation context

# Enter conversation loop
while True:
    # Get user input
    user_input = input("User: ").strip()  # Strip leading and trailing spaces

    # If the user types exit, end the conversation
    if user_input.lower() == "exit":
        print("Exiting chat.")
        break

    # If the user types clean, reset the conversation context
    if user_input.lower() == "clean":
        messages = initial_messages.copy()  # Reset conversation context
        print("Chat history cleared. Starting a new conversation.")
        continue

    # If input is empty, prompt the user and continue
    if not user_input:
        print("Input cannot be empty. Please enter something.")
        continue

    # Add user input to the conversation
    messages.append({"role": "user", "content": user_input})

    # Build the chat template
    text = tokenizer.apply_chat_template(messages, tokenize=False, add_generation_prompt=True)

    # Tokenize input and prepare it for the model
    model_inputs = tokenizer([text], return_tensors="pt").to(model.device)

    # Generate a response from the model
    generated_ids = model.generate(**model_inputs, max_new_tokens=8192)

    # Extract model output, removing special tokens
    generated_ids = [
        output_ids[len(input_ids):] for input_ids, output_ids in zip(model_inputs.input_ids, generated_ids)
    ]
    response = tokenizer.batch_decode(generated_ids, skip_special_tokens=True)[0]

    # Add the model's response to the conversation
    messages.append({"role": "assistant", "content": response})

    # Print the model's response
    print(f"Qwen: {response}")

Troubleshooting Tips

• Model not loading: Ensure that you have a stable internet connection and the `transformers` library is properly installed.
• Errors in input: Ensure inputs are not empty; if they are, the model won’t respond. Always provide something for the AI to work with.
• Model responses are not as expected: This model is still under evaluation. Feel free to tweak the settings and observe any differences.
