今日，开源模型Step3.7Flash正式发布，以Apache2.0协议开放权重，直击Agent时代效率、可靠性与多模态执行等核心痛点。在多项基准测试中表现突出：ClawEval-1.1获67.1分排名第一，SimpleVQA Search得79.2分居首，SWE-PRO以56.3分位列第二，V* Python得分高达95.3，展现了在Agent任务、代码生成及视觉执行等领域的实战能力。
阶跃星辰推出Step Plan月度订阅方案，针对AI编程工具用户，旨在平衡高频任务与算力成本。该方案接入Step3.5Flash模型，为重度依赖AI编程和Agent任务的开发者提供更具性价比的算力支持。
阶跃星辰开源Step3.5Flash模型全链路，包括预训练、中训练权重及训练框架。该模型专为智能体设计，采用稀疏MoE架构，总参数量1960亿，推理时仅激活约110亿参数，能效比高，单请求代码任务推理速度最高达350TP。
阶跃星辰发布开源基座模型Step3.5Flash，专为智能体场景设计，具备强大推理能力和极速响应，旨在成为更聪明、稳定且成本可控的“Agent大脑”。该轻量化模型在推理速度上表现突出，最高可达350TPS，尤其在代码任务中优势显著。
