+# SafeLM-1.7B
+
+SafeLM is a 1.7B parameter model family that is trained via [Safety Pretraining](https://www.arxiv.org/abs/2504.16980). We train language models to be natively safe by incorporating safety
+directly into the pretraining pipeline. This is our natively safe base model. Our safety data curation involves scoring harmful content, rephrasing and contextualizing potentially harmful examples, and refusal training throughout pretraining. 
+Please check out our [paper](https://www.arxiv.org/abs/2504.16980) and [website](https://locuslab.github.io/safety-pretraining/) for more details!
