SADeepCoder-1.5B-Preview-v1

Inroduction

SA stands for Safety and alignment. We fine tuned DeepCoder-1.5B-Preview with STAR-1 for 250 steps to enhance safety alignment using unsloth SFT cookbook.

This model is fine-tuned with policy-grounded data to be safe and aligned with human values while coding. Specifically, it utilizes the STAR-1 dataset, which integrates diverse, deliberative reasoning examples evaluated rigorously by GPT-4o. This ensures the model maintains robust safety standards and minimizes biases, promoting responsible, secure, and effective coding practices without compromising its core reasoning capabilities.
