Stage 1 · How it's built
Post-training
How does it become an assistant?
The stages that turn the reader model into an assistant: examples of good answers, ratings from people and from other models, practice using tools and reasoning, and limits on what not to do.
An image to remember it
Residency after medical school: the same knowledge, now with craft and bedside manner.
The misunderstanding
It learns from my conversations while I use it. The model doesn't change while you talk to it. Training happens beforehand, in the lab. What looks like memory is a trick of the harness.
What changes in practice
The assistant's personality (friendly, cautious, sometimes eager to please) comes from here. It is not a feature of the topic you asked about.
