About elephant-1
elephant-1 is a 9B open-weight decision model from Base Labs, Baseten's research lab, released October 21, 2026. It is a full fine-tune of Qwen3.5-9B that turns a state and typed questions into calibrated probabilities for choice, yes/no and score answers in a single forward pass, without generating free-form text, for routing, classification and rubric scoring. It shares mammoth-1's block-bidirectional attention and 6.21M-example training mix and takes text-only input. Weights are on Hugging Face at baselabs/elephant-1 under MIT. Baseten Model APIs serve it through the System One API (/v1/systemone) as decision-models/baseten-elephant-9b-latest, free through October 27, 2026.
