Google is a leader in DL research. That's a fact. They chose to keep most of their research internal because as above commenters said, they don't have much to gain through it - marketing and hype lasts only so long.

> It's about the UX

what UX? its just a normal frontend mate

> scalability

You do realize Google were serving LLMs before OAI was even hypothesized? Or that they have TPUs which are far more scalable and cost efficient, which could already rip major players apart.

> liability

OAI have fought nothing liability or legality-wise. They just remain in a gray area and hopes no one focuses on them (bad luck, they got caught in the AI art lawsuits too)
