Your AI Assistant Has Amnesia. Andrej Karpathy Just Found the Cure (LLM-Wiki).

Here is a problem you have probably run into without having a name for it. You spend an hour having a brilliant conversation with ChatGPT or Claude. You feed it a research paper, ask sharp questions, get sharp answers. The AI synthesizes connections you had not seen before. You close the tab feeling like you finally understand the topic. Two weeks later, you open a fresh chat and ask a follow-up question. The AI has no idea what you are talking about. It starts from zero. All that work, all those connections - gone.
