Model Details
Model Description
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 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.
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.
