+Tülu 3 is a leading instruction following model family, offering a post-training package with fully open-source data, code, and recipes designed to serve as a comprehensive guide for modern techniques.
+This is one step of a bigger process to training fully open-source models, like our [OLMo](https://allenai.org/olmo) models.
