阶跃星辰（StepFun）称其 Step 3.7 Flash 在与 DeepSeek V4-Flash 的物理编程测试中全面胜出。测试要求在不使用库的情况下，生成一个包含高尔顿板、旋转六边形弹球和同步节拍器三个场景的自包含 HTML5 canvas 动画，并实现真实物理。Step 3.7 Flash 输出 59.6k tokens（耗时 9分57秒），DeepSeek V4-Flash 输出 52.5k tokens（耗时 6分21秒）。尽管 DeepSeek 更快，但 StepFun 模型在物理模拟、视觉效果和逻辑渲染上均占优。主推文指出 Step 3.7 Flash 专为真实世界 agentic 编码任务设计，能保持复杂输出中逻辑、视觉和执行的一致性。

Great demo by @atomic_chat_hq.
Step 3.7 Flash was designed for real-world agentic coding tasks — not just generating code fast, but keeping logic, visuals, and execution coherent across complex outputs.
Love seeing builders test it in creative ways!
StepFun Step 3.7 Flash smashed DeepSeek V4-Flash in a physics contest We gave two open-weight models the same task: write a self-contained HTML5 canvas animation with real physics in one file without libraries. Three scenes - a Galton board, balls bouncing in a spinning hexagon and five metronomes that sync up Outputs: Step 3.7 Flash: 59.6k tokens, 9m 57s DeepSeek V4-Flash: 52.5k tokens, 6m 21s DeepSeek was faster, but that's all it had. StepFun's model won on every front: physics simulation, visuals, and logical rendering of each scene在 X 查看被引用的帖子
