Training:

QwQ-0.5B-Distilled was trained using the amphora/QwQ-LongCoT-130K-2, PowerInfer/QWQ-LONGCOT-500K, and PowerInfer/LONGCOT-Refine-500K with supervised finetuning. This model can be used as a competitive reasoning model on edge devices as well as a draft model for Qwen/QwQ-32B-Preview.

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)

Draft model for Qwen/QwQ-32B-Preview:

This model can be used as a draft model for Qwen/QwQ-32B-Preview in sepculative decoding. We observe out of 5 tokens it generates, on average 3 tokens are accepted for math queries and 2.3 tokens are accepted for general reasoning queries.

---

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.
