Bard is a generative AI chatbot powered by LaMDA. Google has just released Bard, its answer to ChatGPT, and users are getting to know it to see how it compares to OpenAI’s artificial intelligence-powered chatbot.
The name ‘Bard’ is purely marketing-driven, as there are no algorithms named Bard, but we do know that the chatbot is powered by LaMDA.
Bard is an experimental Google chatbot that is powered by the LaMDA large language model.
It’s a generative AI that accepts prompts and performs text-based tasks like providing answers and summaries and creating various forms of content.
Bard is powered by a “lightweight” version of LaMDA.
LaMDA is a large language model that is trained on datasets consisting of public dialogue and web data.
There are two important factors related to the training
A. Safety: The model achieves a level of safety by tuning it with data that was annotated by crowd workers.
B. Groundedness: LaMDA grounds itself factually with external knowledge sources (through information retrieval, which is search).
Google used three metrics to evaluate the LaMDA outputs:
Sensibleness: A measurement of whether an answer makes sense or not.
Specificity: Measures if the answer is the opposite of generic/vague or contextually specific.
Interestingness: This metric measures if LaMDA’s answers are insightful or inspire curiosity.
The future of Bard is currently envisioned as a feature in search. Google’s announcement in February was insufficiently specific on how Bard would be implemented.
The key details were buried in a single paragraph close to the end of the blog announcement of Bard, where it was described as an AI feature in search.
Google’s February 2023 announcement of Bard states that Google will at some point integrate AI features into search
Google’s “Bard” failed spectacularly very first demo by providing false information about James Web Space Telescope. A mistake that caused parent company Alphabet’s stock value drop by more than 7%.
Meanwhile,first picture of Exoplanets was taken by VLT in 2004
On the other hand ChatGPT surprisingly think that,it was Hubble telescope that took first picture of exo planets outside of solar system in 1995 which is ten years before NASA records.
What is ASO? "App Store Optimization", ASO is the process of optimizing mobile apps to improve their visibility and rankings within app stores (such as the Apple App Store and Google Play Store). ASO aims to increase an app's discoverability and attract more organic (non-paid) downloads
FlutterGen Code Generator While working with flutter, to load assets in your Flutter app, you have to reference the asset using path strings, which is not safe. As a Flutter developer, you have no choice but to refer to them using strings directly in your code. Working with images, for instance, is not easy because you have to refer to them by their path string. FlutterGen, a Flutter code generator for your assets that help remove all string-based APIs in your app.
