Import AI 474：Platonic mindspace、太空中的 TPU、智谱启动外层 RSI 循环
Import AI 474: Platonic mindspace; TPUs in space; Zhipu starts an outer RSI loop
Import AI 第 474 期提到智谱（Zhipu）启动外层 RSI 循环，并讨论太空中的 TPU 与 Platonic mindspace。文中还列出有效反馈的三个条件：反馈须足够局部，绑定具体引擎启动参数、代码改动、kernel、输入条件、线程、执行区间或代码路径；反馈须廉价且及时，以缩短验证周期；反馈须支持客观验证，由参考实现、测试结果和可比较的实验指标判定改动是否正确、性能是否提升。

Feedback must be sufficiently local : “It should be tied to specific engine launch parameters, code changes, kernels, input conditions, threads, execution intervals, or code paths, helping the agent narrow the scope of the problem.”
Feedback must be inexpensive and timely to obtain : “Shorter validation cycles help the agent correct course promptly and spend less effort on unproductive hypotheses.”
Feedback must support objective verification : “Whether a change is correct and whether performance has improved should be determined by reference implementations, test results, and comparable experimental metrics.”
