Example Usage:

import torch
from transformers import AutoModelForCausalLM, AutoTokenizer
# Model name
model_name = "kz919/QwQ-0.5B-Distilled-SFT"
# Load the model
print(f"Starting to load the model {model_name} into memory")
model = AutoModelForCausalLM.from_pretrained(
    model_name,
    torch_dtype=torch.bfloat16,
    device_map={"": 0}
)
# Load the tokenizer
tokenizer = AutoTokenizer.from_pretrained(model_name)
# Define the prompt
prompt = "How many r in strawberry."
messages = [
    {"role": "system", "content": "You are a helpful and harmless assistant. You are Qwen developed by Alibaba. You should think step-by-step."},
    {"role": "user", "content": prompt}
]
# Tokenize the input
text = tokenizer.apply_chat_template(
    messages,
    tokenize=False,
    add_generation_prompt=True
)
model_inputs = tokenizer([text], return_tensors="pt").to(model.device)
# Generate a response
generated_ids = model.generate(
    **model_inputs,
    max_new_tokens=4096
)
generated_ids = [
    output_ids[len(input_ids):] for input_ids, output_ids in zip(model_inputs.input_ids, generated_ids)
]
# Decode the response
response = tokenizer.batch_decode(generated_ids, skip_special_tokens=True)[0]
print(response)

Applications:

1. Conversational Assistants:
   Suitable for AI chatbots that require reasoning and long-context understanding.

2. Educational Tools:
   Provides step-by-step explanations, making it ideal for learning environments.

3. Creative Writing:
   Assists in generating coherent, contextually aware long-form content.

4. Technical Support:
   Handles complex customer queries with precision and clarity.

Limitations:

• While distilled for efficiency, performance on highly complex reasoning tasks may slightly trail the teacher model.
• This model could still be under trained, merely a proof of concept. Don't yell at me if it's outputing nonesense.
