You have two options:
1. Work full-time for companies doing this state-of-the-art stuff (OpenAI, Meta, etc.)
2. Work full-time for a (good) AI company that is doing interesting AI work, but most likely not based on GPT/SD/etc.
In both cases, you will learn a lot. Anything else seems like a costly and dangerous distraction to me.
