UnverifiedSoft prompts have three fundamental limitations: they are deeply bound to a specific model architecture and cannot be transferred across models; the continuous vectors cannot be directly understood by humans; and they require access to the model's internal embedding layer during inference, making them incompatible with commercial models that provide only API access.73% similarUnverifiedPrompt engineering has a ceiling: no matter how cleverly a prompt is designed, it can only make selections within the model's existing capability space and cannot break through the model's inherent capability boundaries.73% similarUnverifiedThe fundamental limitation of Prompt Engineering lies in its statelessness—each interaction is independent, and the model cannot accumulate an understanding of the overall project.72% similar
