dfurman/Qwen2-72B-Orpo-v0.1

Model

This model is a finetune of Qwen/Qwen2-72B-Instruct on 1.5k rows of mlabonne/orpo-dpo-mix-40k. It was trained as a generalist language model for a variety of text generation use cases, including support of agentic capabilities, roleplaying, reasoning, multi-turn conversations, long context coherence, and more.

Thanks go out to mlabonne, Qwen, et al. for the source dataset and base model.

Run

question = """The bakers at the Beverly Hills Bakery baked 200 loaves of bread on Monday morning. 
They sold 93 loaves in the morning and 39 loaves in the afternoon. 
A grocery store then returned 6 unsold loaves back to the bakery. 
How many loaves of bread did the bakery have left?
Respond as succinctly as possible. Format the response as a completion of this table:
|step|subquestion|procedure|result|
|:---|:----------|:--------|:-----:|"""


messages = [
    {"role": "system", "content": "You are a helpful assistant."},
    {"role": "user", "content": question},
]
prompt = tokenizer.apply_chat_template(messages, tokenize=False, add_generation_prompt=True)
# print("***Prompt:\n", prompt)

print("***Generation:")
print(outputs[0]["generated_text"][len(prompt):])

***Generation:
|1|Initial loaves|Start with total loaves|200|
|2|Sold in morning|Subtract morning sales|200 - 93 = 107|
|3|Sold in afternoon|Subtract afternoon sales|107 - 39 = 68|
|4|Returned loaves|Add returned loaves|68 + 6 = 74|
