Free user here. Why does chatgpt trail off to disjointed incoherent responses suddenly especially every few hours? It in a way loses track of the immediate preceeding communication context and tries to pick up from random points of conversation varying from even hours or minutes away. From then on it gets impossible to continue so I have to establish a fresh chain of communication in a new chat. This is especially problemmatic if Im in the middle of building something when it trails off.
