Never saw an official announcement from OpenAI about the ChatGPT or any other AI token, so I would be vigilant around those.
Sam Altman is the developer of OpenAI and he's also part of the company that has developed Worldcoin. As for Chatgpt, it's also owned and developed by OpenAI which Sam was part of it. But I think in the latter, he has stepped down or fired or sold his shares, I didn't know what happened next. And what OP is saying about chaingpt, it looks like a company that develops AI products. Maybe it's good if they're into that development but they don't need to have any tokens anymore because the market is so crowded with that.
