When was Google Bard announced?

Bard was unveiled on February 6 in a statement from Google and Alphabet CEO Sundar Pichai. Even though Bard was an entirely new concept, the AI chat service that was launched was powered by Google’s Language Model for Dialogue Applications (LaMDA), which was unveiled two years prior. 

How does Google Bard work?

Google Bard is now powered by Google’s very own and most advanced large language model (LLM) PaLM 2, which was unveiled at Google I/O 2023.

PaLM 2 — a more advanced version of PaLM, which was released in April 2022 — will allow Bard to be much more efficient and to perform at a higher level.

The initial version of Bard used a lightweight model version of LaMDA, because it required less computing power and could be scaled to more users. 

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

Google’s decision to use its own LLMs, LaMDA and PaLM 2, was a bold decision from Google since some of the most popular AI chatbots right now, including ChatGPT and Bing Chat, use a language model in the GPT series.
