InternLM 开源多模态决策模型 Intern-Decision,4B 版本七套基准平均准确率 90.02%
InternLM 发布开源多模态决策模型 Intern-Decision,将状态、可选图像和多个带类型的问题转化为带概率的决策,支持 choice、score 和 noul(是/否)三类问题,训练时微调 Qwen3.5 的语言主干并冻结视觉塔和投影器。Intern-Decision-4B 在七套基准上平均准确率 90.02%,RTX 4090 本地平均请求延迟 44.16 ms,在 96 例校准基准上 Brier 为 0.550、ECE 为 0.089。该版本包含训练、两种推理后端、基准评分、温度校准和浏览器 demo,但训练数据、校准与验证记录、图像及模型权重未包含在内。
