# OpenCodeReasoning-Distill-Qwen-7B-Instruct

## Model Overview 

OpenCodeReasoning-Distill-Qwen-7B-Instruct is a large language model (LLM) which is a derivative of [Qwen2.5-7B-Instruct](https://huggingface.co/Qwen/Qwen2.5-7B-Instruct) (AKA the *reference model*). 
It is a reasoning model that is post trained for reasoning while code generation. The model supports a context length of 32K tokens.

This model is ready for commercial use.

## Model Version  
1.0 (4/21/2025)

## Quick Start and Usage Recommendations:

We recommend setting temperature to `0.6`, and Top P to `0.95` for inference on LiveCodeBench.

### Use It with Transformers
See the snippet below for usage with [Hugging Face Transformers](https://huggingface.co/docs/transformers/main/en/index) library. Please see the example below.

We recommend using the *transformers* package with version 4.48.3.   
Example:

```py
import torch
import transformers

model_id = "nvidia/OpenCodeReasoning-Distill-Qwen-7B-Instruct"
model_kwargs = {"torch_dtype": torch.bfloat16, "trust_remote_code": True, "device_map": "auto"}
tokenizer = transformers.AutoTokenizer.from_pretrained(model_id)
tokenizer.pad_token_id = tokenizer.eos_token_id

pipeline = transformers.pipeline(
   "text-generation",
   model=model_id,
   tokenizer=tokenizer,
   max_new_tokens=32768,
   temperature=0.6,
   top_p=0.95,
   **model_kwargs
)

print(pipeline([{"role": "user", "content": "Solve x*(sin(x)+2)=0"}]))
```

User Prompt Template (without starter code):

````
"You will be given a question (problem specification) and will generate a correct Python program that matches the specification and passes all tests.

Question: {prompt}

Read the inputs from stdin solve the problem and write the answer to stdout (do not directly test on the sample inputs). Enclose your code within delimiters as follows. Ensure that when the python program runs, it reads the inputs, runs the algorithm and writes output to STDOUT.
```python
# YOUR CODE HERE
```
````

User Prompt Template (with starter code):

````
You will be given a question (problem specification) and will generate a correct Python program that matches the specification and passes all tests.

Question: {prompt}

You will use the following starter code to write the solution to the problem and enclose your code within delimiters.
```python
{starter_code}
```
