## Model Details

### Model Description

<!-- Provide a longer summary of what this model is. -->

This is a 32B reasoning model trained from Qwen2.5-32B-Instruct with 17K data. The performance is on par with o1-preview model on both math and coding.
Please see our [blog post](https://novasky-ai.github.io/posts/sky-t1/) for more details.

- **Developed by:** NovaSky Team from Sky Computing Lab at UC Berkeley.

## Training Details

### Training Data

17K verified correct responses from Qwen/QwQ-32B-Preview on coding, math. In addition, we add the science portion from the [Still-2 paper](https://arxiv.org/pdf/2412.09413).

### Training Procedure
We perform supervised fine tuning on the data, with a batch size of 96.

#### Speeds

We use Llama-Factory for training. On 8 H100, the training takes 19 hours with DeepSpeed Zero-3 Offload.
