Google explains that Bard is an experimental conversational AI service based on LaMDA (Language Model for Dialogue Applications).
LaMDA was announced two years ago at the 2021 Google I/O keynote as Google’s next generation of voice and conversational capabilities. Now it is used to create these answers for users.
Bard is powered by a lightweight model version of LaMDA that requires “significantly less processing power,” Google said. Google said this will allow it to scale to more users while allowing for more feedback.
