How to Use the Qwen 2.5-14B Instruct Abliterated Model

In the rapidly evolving world of artificial intelligence, having access to powerful models is key to creating engaging and interactive applications. One such model is the Qwen 2.5-14B Instruct Abliterated by Alibaba Cloud. This model offers a range of features and customization options, allowing developers to create chatbots and assistants that improve user experience! In this guide, we’ll walk you through setting up and utilizing this incredible model.

Installation and Setup

To get started, you’ll first need to install the Hugging Face Transformers library if you haven’t already. You can do this via pip:

pip install transformers

Loading the Model

For our chatbot, we’ll leverage the Qwen 2.5-14B Instruct Abliterated model. Here’s how you can load it:

from transformers import AutoModelForCausalLM, AutoTokenizer

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

Utilizing the Model for Conversations

Imagine the model as a friendly librarian. When you walk into a library and ask a question, the librarian (model) gathers information based on your request (user input). Then, they provide a detailed response from the library’s extensive collection (training data).

Here’s how you can implement the conversation feature:

# 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:
    user_input = input("User: ").strip()  
    if user_input.lower() == "exit":
        print("Exiting chat.")
        break
    if user_input.lower() == "clean":
        messages = initial_messages.copy()
        print("Chat history cleared. Starting a new conversation.")
        continue
    if not user_input:
        print("Input cannot be empty. Please enter something.")
        continue
    messages.append({"role": "user", "content": user_input})

    text = tokenizer.apply_chat_template(messages, tokenize=False, add_generation_prompt=True)
    model_inputs = tokenizer([text], return_tensors='pt').to(model.device)

    generated_ids = model.generate(**model_inputs, max_new_tokens=8192)
    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]

    messages.append({"role": "assistant", "content": response})
    print(f"Qwen: {response}")

Troubleshooting Tips

While using the model, you may encounter some common issues. Here are a few troubleshooting steps you can follow:

• Model Not Loading: Ensure you have the correct model name and internet connection. Check if the Hugging Face API is accessible.
• Device Compatibility: If running into device compatibility issues, confirm that your machine supports the required PyTorch version.
• Input Errors: If the input prompts an error, remember to sanitize your input. Any unwanted characters could break the conversation format.
• Disconnected Responses: If responses feel disconnected or irrelevant, feel free to reset the conversation context using the “clean” command.
