How does Google Lamda work?
What we understand from this project move is that Google is trying to bring human-like conversations into their chatbot systems since they have this distinctive nature.
Generally, we start conversations with one topic and then end up in a totally different topic of matter. Humans naturally drive the conversations forward by connecting topics in the most unexpected ways.
By tackling these scenarios, LaMDA will eventually revolutionize chatbot systems completely. A chatbot with these superior abilities could perfectly engage in natural conversations with people. We will be able to ask for information or consult the internet more naturally.

LaMDA has also gone a step further. The system succeeds at detecting the sensibleness of the conversation — whether the words would make sense in the current context of a conversation — and is better able to keep its responses specific.
LaMDA’s conversational skills are built on an architecture that produces a model which will be trained to read multiple words (a sentence or paragraph, for example), to pay attention to how those words relate with one another, and make predictions on the words that should come next.
Currently, in order to trigger google assistant, users have to say “Hey Google”, then the specific commands like “turn on the lights” and so on. Now futuristic assistants like LaMDA will make such commands more natural, or actually aid conversations with such systems.
They will enhance chatbots and other automation applications. It could be integrated with Google’s other tools like Google Maps, etc. The exact functioning along with the challenges of LaMDA can be determined only after it has fully rolled out, which brings us to the next most important question.
Is It Ready For Use?
Currently, LaMDA has not been officially rolled out for commercial or personal use. It is still in the development and testing stage. It is expected to roll out in the coming years. And there is a possibility of a few challenges that the system might face which will emerge with time.
During the Google I/O conference, the team demonstrated LaMDA’s conversation speaking as Pluto and paper plane in two different conversations. The team didn’t have to change LaMDA’s mechanics from impersonating Pluto to a paper plane for conversing.
LaMDA shows the following key qualities: sensibleness, specificity, interestingness, and also factuality. Here’s an example from their conversation with LaMDA impersonating Pluto and how it maintained these qualities:
1. Specificity: When the team questioned LaMDA about what we would see when we will visit Pluto in a flyby? It responded with “You would get to see a massive canyon, some frozen icebergs, geysers, and some craters.” The system could have said something along the lines of “An Icy Surface” or “Dwarf planet with lots of craters” but the response was very specific on details of Pluto’s geology.

2. Factuality: When the team then asked if Pluto ever had any visitors, the system responded, “I have had some. The most notable was New Horizons, the spacecraft that visited me.” This information was true because NASA had launched the New Horizons mission in 2006 to photograph Pluto and its moons from up close.

3. Interestingness: The team questioned LaMDA about what it wanted people to know about pluto, to which it responded, “I wish people knew I am not just a random ice ball. I am actually a beautiful planet.” This part of the conversation showed a bit of emotion, wherein it wanted people to know it better.

4. Sensibleness: After LaMDA said that it wished people knew Pluto was indeed a beautiful planet, the team responded “Well I think you’re beautiful,” for which LaMDA replied: “I’m glad to hear that. I don’t get the recognition I deserve. Sometimes people refer to me as just a dwarf planet.”

It even went on to explain why it wished it was better known. From a natural conversation point of view, this makes total sense. Even when someone supports our wishes, we may be expressing them to let the emotions flow. LaMDA doesn’t have emotions, but it perfectly captures that sensation here.
