They don’t have persistent memory though. Models are static, what you have is a model that will reprocess the whole series of prompts + some data fetched from a data store. A harness is just a while loop prompting an LLM and executing tool calls, but the model is purely static

The model does not. The system it runs in can. My agents have persistent memory. It is not at all clear whether or the distinction that the long-term memory is external from the model matters.
