That’s a very solvable problem though. If Microsoft decides to integrate ChatGPT with bing, they have the resources to retrain the model on a more recent data set, and even do it somewhat regularly
You don't even need to retrain if you use retrieval transformers. That is the real revolution waiting to happen. Deepmind already unlocked it with RETRO, but I don't know why a public version hasn't been released - hooked into the live internet.
