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。
