Ask HN: How to access/use GPT-3?

Hi all, I've been reading impressive things about and/or generated by GPT-3 and I can't wait to try it myself. Unfortunately, I know that there's a waiting list to use it directly from the OpenAI platform and I have my doubts I'll actually be approved or when that'll happen. Are there alternative avenues to test this model? I've read that the game AI Dungeon uses GPT-3, so one could use it to test the model, but I've heard it has some limitations w.r.t using the model directly (although not clear which kind of limitations/differences exactly). Any other alternatives besides buying 300GPUs?
