Is it still learning from ongoing conversations? I thought its grasp of context was purely limited to a single conversation, so if for instance you taught it something, it would never share that with me, or with you a few days later.
In this case, they used that phrase in continuing the conversation to reinforce the context and guide the bot's responses
My understand is the bot doesn't actively learn from conversations, or use information between conversations, though it all probably helps OpenAI when they retrain the model using the chats.
