Google co-founder Sergey Brin, who left his executive role in 2019, is now working alongside artificial intelligence (AI) researchers on Google’s next big AI system, Gemini, a model that seeks to surpass OpenAI’s ChatGPT-4 capabilities, according to The Wall Street Journal.
The billionaire has been going to the technology giant’s offices in Mountain View, California, three to four days a week in recent months.
According to the newspaper, Brin works closely with the group of researchers who are creating Google’s new artificial intelligence model.
The billionaire has taken part in decisions on the performance of an AI program over time, participated in the hiring of researchers and called weekly meetings.
The goal of Gemini – a project supervised by Demis Hassabis – is to be as or more powerful than GPT-4, an OpenAI generative AI chatbot that is also used by Microsoft and could be available later this year.
The current CEO, Sundar Pichai, according to the outlet, is enthusiastic about Brin’s involvement and encourages his contributions.
Brin created Google with Larry Page in 1998, when they were studying for a PhD at Stanford University.
Brin is the second largest individual shareholder in Google parent Alphabet, behind Page, with a stake valued at about $90 billion (80.87 billion euros), according to data from S&P Capital IQ.
Currently, Brin ranks tenth among the world’s great fortunes, with a net worth that reaches 104,000 million dollars, according to the billionaires index of Bloomberg.
