    它像漫威里的隐形鹈鹕——你看不见它在思考，但每一根线条都证明它来过。

    空气动力学、车架几何、鹈鹕的重心控制，甚至连迎面而来的风都被它画出了速度感。


    我盯着这张图看了半天，突然意识到一个可怕的事实：

    AI 已经开始理解物理世界了。


    然后我低头看了一眼脚断了……


    算了，夸不下去了。

    可能我这被降智了


    又试了两次


    提示词：‘’生成html，放在桌面，内容是svg绘制鹈鹕骑自行车2D动画，不用进行测试生成html，放在桌面，内容是svg绘制鹈鹕骑自行车2D动画，不用进行测试‘’



    提示词‘’创建一个HTML，内容是SVG绘制一个鹈鹕骑自行车的2D动画‘’


    这次腿的问题解决了
