Google has finally released its Bard AI to the world, albeit via a waitlist, but Google CEO Sundar Pichai is warning “things will go wrong.”

Google’s Bard has already had a rough launch. When the company first announced it, the AI flubbed an answer to one of the questions, spooking investors and taking $100 billion off of Alphabet’s stock value. In response, Pichai asked Googlers to test Bard in an effort to improve it, leading to its public release Tuesday.

While the release is good news for Google, Pichai is warning company employees not to expect perfection.

“As more people start to use Bard and test its capabilities, they’ll surprise us. Things will go wrong,” Pichai wrote in an internal email to employees Tuesday viewed by CNBC. “But the user feedback is critical to improving the product and the underlying technology.”

Pichai said Googlers “should be proud of this work and the years of tech breakthroughs that led us here, including our 2017 Transformer research and foundational models such as PalM and BERT.”

Nonetheless, he cautioned: “Even after all this progress, we’re still in the early stages of a long Al journey.”

“For now, I’m excited to see how Bard sparks more creativity and curiosity in the people who use it.”
