50 per 3 hours isn't so bad when I am using it. Writing a prompt + the response takes a minute, then it takes a couple minutes on average to go over the response and only then do I end up asking again. In using it I've only ended up hitting the limit a few times, and most of those times it's been a few minute wait.

API access can get you more if you would like, you would just have to use a different UI or make your own.
