Google demos LaMDA, a next-generation AI for dialogue

During a keynote address at Google I/O 2021, Google’s annual developer conference, the company announced LaMDA, a sophisticated language model that Google says is far better at understanding the context of conversations than leading models today. Google CEO Sundar Pichai says that LaMDA, which was built for dialogue applications, is open domain and designed to converse on any topic. Importantly, the model doesn’t have to be retrained to have another conversation.

“While it’s still in research and development, we’ve been using LaMDA internally to explore novel interactions,” Pichai said. “For example, say you wanted to learn about one of my favorite black planets — Pluto. LaMDA already understands quite a lot about Pluto and millions of other topics.”

Data scientists don’t have to hand-program concepts into LaMDA, because none of the model’s responses are predefined. LaMDA attempts to answer with sensible responses, keeping the dialogue open-ended and generating natural conversations that never take the same path twice.

“It’s really impressive to see how LaMDA can carry on a conversation about any topic,” Pichai said. But he admitted that the model isn’t perfect. “It’s still early research, so it doesn’t get everything right. Sometimes it can give nonsensical responses,” he said.
