# daVinci-origin-3B

**daVinci-origin-3B** is a fully transparent, 3-billion parameter foundation model trained from scratch. It serves as a "clean-room" baseline for the research paper [*Data Darwinism -- Part1: Unlocking the Value of Scientific Data for Pre-training*](https://arxiv.org/pdf/2602.07824).

Unlike most open-source models, daVinci-origin-3B was explicitly trained on a dataset **strictly excluding scientific content** (books and research papers). This unique design allows researchers to unambiguously attribute performance gains to specific domain data injection strategies during continued pre-training.
