Is truth gpt on Coinbase?

Excuse me, I've been hearing some buzz about GPT and its potential involvement with Coinbase, a leading cryptocurrency exchange. Could you please clarify if there's any truth to the rumor that GPT, or perhaps you're referring to a specific entity or technology related to it, is indeed on Coinbase? I'm particularly interested in understanding if there's been any official announcement or partnership between the two. It would be greatly appreciated if you could shed some light on this matter.
