Pichai then illustrated LaMDA's conversational skills by presenting a conversation about Pluto between a person and LaMDA, with the AI model responding as if it were the dwarf planet. Missing from the sample dialog were any of the nonsensical statements or misunderstandings that anyone who has engaged with conversational AI inevitably encounters, though LaMDA is still capable of messing up. "It's really impressive to see how LaMDA can carry on a conversation about any topic," said Pichai. "It's amazing how sensible and interesting the conversation is yet. It's still early research, so it doesn't get everything right. Sometimes it can give nonsensical responses."
