Parker Ortolani blogging about the new ChatGPT feature to look at past conversations:

…it makes the tool dramatically more intelligent — and personal. By being able to reference things you have talked about before without hoping that the model would catch it or by manually teaching it, it feels more like talking with a person than ever before.

In all the talk of AI models and the technical bits, many people miss that ChatGPT is a success because it’s an actual product now. A competitor can’t “catch up” to ChatGPT unless they also build everything that OpenAI has added around the model.
