They are open-source and free to try for a week. Authors Max Kirkby Michael Psenka Thomas Villeneuve Aaryam Sharma Charles O'Neill Chloe Florit Ardin Lo Published October 21, 2026 Share Published October 21, 2026 We’re proud to release two of the world’s best decision models, trained by our own research lab: mammoth-1 (27B) and elephant-1 (9B)! mammoth-1 ranks #1 out of 208 decision models, and elephant-1 is the leading 9B decision model on the Jev Decision Index. Both models are open-source and free to try for a week on Baseten Model APIs, with zero data retention (ZDR) by default. ✕ mammoth-1 leads the Jev Decision Index 0.4 with a score of 71.24; elephant-1 is the top 9B model. On the Artificial Analysis Decision Index, mammoth-1 scores 65.9 and elephant-1 65.2. Since TypeSafe introduced Jev and the System One API, decision models have emerged as a new category.
