UnverifiedNegative constraints narrow the probability space by explicitly excluding undesired outputs, are equally important as positive instructions, and can reduce deviations caused by the model's creative improvisation.77% similarUnverified对大语言模型而言，「不要做X」的负向约束有时比「要做Y」的正向指令更有效，因为负样本相当于在概率空间中设置了禁区73% similarUnverified覆盖率本质上是负向指标，能告诉你哪些代码没有被执行，却无法保证被执行的代码被正确断言72% similarUnverified规格越详细代码质量越稳定，因为每个明确约束都压缩了 Agent 的不确定性空间71% similarUnverifiedModel compression techniques (distillation, pruning, quantization) incur minimal loss on high-frequency, regular tasks, but significantly degrade multi-step reasoning that requires long-range dependencies—a capability that cross-component state management in front-end interaction code heavily relies on.70% similar
