Do AI models actually have memory? No. On their own they store nothing, so ask a follow-up and the model forgets what you said unless it's inside the context. So how does an agent stay coherent across multiple steps? You feed the whole conversation back in. Every single turn, the entire history gets sent into the context window again. The model isn't remembering; it's rereading everything that happened, every time. #techwithtim #ai #aiengineer
