Google is training its robots to be more like humans

Language models work by taking huge amounts of text uploaded to the internet and using it to train artificial intelligence software to guess what kinds of responses might come after certain questions or comments. The models have become so good at predicting the right response that engaging with one often feels like having a conversation with a knowledgeable human. Google and other companies, including OpenAI and Microsoft, have poured resources into building better models and training them on ever-bigger sets of text, in multiple languages.
