Thinking Machines 发布 Inkling 2 Small，称最强西方开放权重模型
原标题：Thinking Machines' Inkling 2 Small claims top spot among western open-weight models
AI 摘要
前OpenAI CTO Mira Murati 创办的 Thinking Machines 发布第二代模型 Inkling 2 Small，这是一个总参数 5940 亿、每次激活 170 亿的混合专家模型，支持文本与图像输入并可调节思考深度。其在 Artificial Analysis 智能指数上得分 31，比前代提升 18 分，与 Gemini 3.8 Flash 大致相当，智能体任务提升尤为明显。代价是单任务输出 token 约为前代四倍、成本约为六倍（每任务 1.18 美元），但仍远低于 Gemini 3.8 Flash 和 Claude Sonnet 5.5。模型目前通过 Tinker 平台以专有形式提供，待外部安全测试完成后将以 Apache 2.0 许可开放权重。
