Google Bard

Google Bard is an experimental chat service powered by Google's Language Model for Dialogue Applications (LaMDA), which was unveiled two years ago. Unlike ChatGPT, which relies solely on its own model, Bard utilizes information from the web to provide responses.

Bard was officially announced on February 6 by Google and Alphabet CEO Sundar Pichai. The initial version of Bard uses a lightweight model version of LaMDA, which requires less computing power and can be scaled to more users. In addition to LaMDA, Bard draws on all the information from the web to provide fresh and high-quality responses.

LaMDA was built on Transformer, Google's neural network architecture that it invented and open-sourced in 2017. Interestingly, GPT-3, the language model that ChatGPT uses, was also built on Transformer, according to Google.
