Step 5 Preview 实测:发动机动画与三维抓娃娃机两个编程任务对比
阶跃星辰9月20日发布 Step 5 Preview,采用稀疏MoE架构,总参数600B、每Token激活27B,支持1M上下文和视觉输入,在 Artificial Analysis Intelligence Index v4.3 得分44。实测中,四冲程发动机动画任务它用10分39秒零纠错通过,比 DeepSeek-V4.1-Flash 慢4秒。三维抓娃娃机任务用时39分19秒,慢于 GPT-5.6 Sol 的16分38秒,但抓取判定日志最完整。官方称其单任务成本仅为 GLM-5.3 和 Kimi K3 的35%。
