Hey folks, I appreciate the love and the eagerness to bring @gork back. Unfortunately it’s not in my power to do so. I’m sure he’ll be back eventually and I’m just as sad that he is gone as you are. I won’t be claiming any token. Cheers.

I joined xAI at 18 years old. Today, I'm moving onto new things. It's been an insane year. Leading personality & model behavior posttraining for Grok 4.1. Building @gork and memory. And the people were fucking incredible. I cannot wait to see the crazy future you'll build!
