This submission reflects on the milestones of the first three years to introduce the audience to the Pythia Portal, Pythia Platform, Pythia Foundations, and Pythia Cookbooks. We highlight technical and community successes along the way, including a focus on GitHub and Jupyter Book infrastructure to support community authorship, attribution, and reproducibility in Pythia Cookbooks. To these ends, Project Pythia has developed automated infrastructure for code and content health-checks, tested reproducibility, and standards-based citation generation. We review 2023 for the project, including development of this infrastructure and hosting of the synchronous 2023 Pythia Cook-Off hackathon for cookbook generation. This hybrid event was attended by over 45 people virtually and in-person, and resulted in more than 10 Pythia Cookbooks created and more elevated by new content. From here, Project Pythia looks towards the next three years, and we introduce plans for exciting upcoming efforts with new support from the NSF.
