Assistants API Limit still 60? And alternatives

Hi, I’ve found a few posts regarding this rate limit, and as found here it still appears to be 60.

So first, do we know if this going to change at all, or is there a way to contact openai to get a different limit for your api?

Or second, what are some alternatives?
I’m mainly interested in being able to have a specific instance that can store data specific to each user, in which just that user can access it. Kind of like how chatgpt works on scale right now, but as a saas instead.
