The Pixel 6 contains Google's "Tensor" processor, which it says enables new phone features powered by artificial intelligence and machine learning.
It is also the first phone in the series with a "Pro" model, designed to compete at the high end of the market.
"The whole goal when we started was to reach this point," said Rick Osterloh, Google's head of devices.
"Really, this is our original vision that we're finally able to get to after building a lot of capabilities both in technology and in product development capabilities," he told the BBC.
