Before LaMDA, which was announced in 2021, there was Meena, which was first known in early 2020. Then the Google Brain team published a research paper describing a chatbot that can “chat about anything”.
At the time, the team wanted to release the tool on a limited basis, as OpenAI did with GPT-2, but Google management rejected the offer on the grounds that the chatbot did not comply with the company’s artificial intelligence principles regarding security and fairness.
Meena soon became LaMDA as it had more data and processing power. The post writes that currently, in 2020, the team is “looking into ways to integrate LaMDA into Google Assistant.” Experiments started using LaMDA in Google Assistant. However, Google administrators did not make the chatbot available to everyone.
All these delays and bans have led to Microsoft already improving the AI chatbot on Bing with might and main and Google is still there.
