Unverified小模型长上下文理解质量随长度下降快，通常超过4K-8K token窗口后表现退化77% similarUnverifiedLow-end AI models have smaller context windows, potentially only 8K–32K tokens, which prevents them from fully understanding the complete logic of existing features when modifying new ones, resulting in regression defects.76% similarUnverifiedEven for large models that support 128K tokens, attention decay is a practical concern in actual use—the model's attention to information in the middle of the window is significantly lower than at the beginning and end.75% similarUnverified上下文窗口大小不等于有效上下文长度，超出有效注意力范围会导致遗忘漂移现象71% similarUnverifiedContext window limitations cause the model to prefer breaking large tasks into smaller chunks to avoid exceeding its capacity in a single generation.69% similar
