Google I/O: Alphabet unveils beefed-up AI chatbot as competition heats up

Google parent Alphabet on Tuesday showed how it is building on artificial intelligence across its businesses, including a beefed-up Gemini chatbot and improvements to search, as it faces growing competition from OpenAI and other rivals.

At its annual I/O developer event in Mountain View, California, CEO Sundar Pichai said the company is rolling out AI Overviews to all users in the U.S. this week after a long period of public testing since last year.
