In a blog post,  Sundar Pichai, CEO of Google and parent company Alphabet, said in a statement: "We’ve been working on an experimental conversational AI service, powered by LaMDA, that we’re calling Bard. And today, we’re taking another step forward by opening it up to trusted testers ahead of making it more widely available to the public in the coming weeks."

"Bard seeks to combine the breadth of the world’s knowledge with the power, intelligence and creativity of our large language models. It draws on information from the web to provide fresh, high-quality responses. Bard can be an outlet for creativity, and a launchpad for curiosity, helping you to explain new discoveries from NASA’s James Webb Space Telescope to a 9-year-old, or learn more about the best strikers in football right now, and then get drills to build your skills," he wrote.

What is Chat GPT:

ChatGPT (Chat Generative Pre-trained Transformer) is a chatbot launched by OpenAI in November 2022.

ChatGPT is an AI tool that gives natural sounding answers to questions posed by users across many domains of knowledge.

The chatbot uses text prompts to create content including essays, jokes, poetry and job applications, reports The Guardian.

It is built on top of OpenAI's GPT-3 family of large language models and is fine-tuned (an approach to transfer learning) with both supervised and reinforcement learning techniques.

ChatGPT was launched as a prototype on November 30, 2022, and quickly garnered attention for its detailed responses and articulate answers across many domains of knowledge.
