Baseten Base Labs 发布决策模型 mammoth-1 与 elephant-1
Baseten 旗下 Base Labs 发布两个决策模型 elephant-1(9B)和 mammoth-1(27B),均基于 Qwen3.5 全量微调,并公开模型权重。mammoth-1 在 Jev Decision Index 0.4 上以 71.24 分位列 208 个模型第一,领先第二名 Perplexity Decider v1.2 1.8 分;elephant-1 在该榜得 62.65 分,在 Artificial Analysis Decision Index 上以 65 分与 d1-ultra 并列第一。训练使用 6.21M 样本的第八版数据混合,并在全注意力层改用块双向注意力掩码,固定数据下该改动使公开 10k 样本得分从 44.8 升至 48.6。

n the world on the Jev Decision Index (beating Jev 1.14) and tied with the previous best decision model d1-ultra on the Artificial Analysis Decision Index. It beats models such as Microsoft-Decision-1, Perplexity Decider v1.1 27B and Jev. Figure 1 Comparative performance of mammoth-1 and elephant-1 on the Jev Decision Index and Artificial Analysis Decision Index. mammoth-1 leads the Jev Decision Index at 71.24; elephant-1 is the top 9B model. On the Artificial Analysis Decision Index, mammoth-1
