Are you ready to dive into the world of AI reasoning? In this guide, we’ll explore how to use the QuantFactory reasoning model, which is a quantized version of the KingNish reasoning model. With its impressive capabilities, this model provides a seamless way to perform reasoning and generate responses. Let’s get started!

Model Overview

The QuantFactory reasoning model is based on the QwenQwen2.5-0.5B-Instruct architecture and has been designed to excel in text generation inference. Here’s a quick breakdown of the model’s characteristics:

• Base Model: QwenQwen2.5-0.5B-Instruct
• License: Apache-2.0
• Datasets Used: KingNishreasoning-base-20k
• Key Features: Efficient reasoning and response generation

Set Up the Model

To get started, you need to install the necessary libraries and set up the model. The main programming language used here is Python. Below is a code snippet to initialize the model:

from transformers import AutoModelForCausalLM, AutoTokenizer

MAX_REASONING_TOKENS = 1024
MAX_RESPONSE_TOKENS = 512
model_name = "KingNishReasoning-0.5b"

model = AutoModelForCausalLM.from_pretrained(model_name, torch_dtype="auto", device_map="auto")
tokenizer = AutoTokenizer.from_pretrained(model_name)

Generating Reasoning

Imagine asking a friend to solve a math problem but first needing them to think about it. Similarly, the model performs reasoning before generating a response. Here’s how it works:

prompt = "Which is greater, 9.9 or 9.11?"
messages = [{"role": "user", "content": prompt}]

reasoning_template = tokenizer.apply_chat_template(messages, tokenize=False, add_reasoning_prompt=True)
reasoning_inputs = tokenizer(reasoning_template, return_tensors="pt").to(model.device)

reasoning_ids = model.generate(**reasoning_inputs, max_new_tokens=MAX_REASONING_TOKENS)
reasoning_output = tokenizer.decode(reasoning_ids[0, reasoning_inputs.input_ids.shape[1]:], skip_special_tokens=True)

print("REASONING: ", reasoning_output)

Generating the Final Answer

Once the model processes the reasoning, it’s time for it to deliver the final answer. This is akin to your friend, after thinking, finally giving you an answer to your math problem. Here’s how to generate the answer:

messages.append({"role": "reasoning", "content": reasoning_output})

response_template = tokenizer.apply_chat_template(messages, tokenize=False, add_generation_prompt=True)
response_inputs = tokenizer(response_template, return_tensors="pt").to(model.device)

response_ids = model.generate(**response_inputs, max_new_tokens=MAX_RESPONSE_TOKENS)
response_output = tokenizer.decode(response_ids[0, response_inputs.input_ids.shape[1]:], skip_special_tokens=True)

print("ANSWER: ", response_output)

Troubleshooting Tips

Like any technology, you might run into a few bumps while using the QuantFactory reasoning model. Here are some common issues and solutions:

• Issue: Model not loading properly.
  • Solution: Make sure all dependencies are correctly installed. Try reinstalling the Transformers library and any other required packages.
• Issue: Slow inference times.
  • Solution: Ensure you are running the model on a capable device, preferably with a GPU. Try optimizing the model using available options in the Transformers library.
