For Plus users the limits are:

o3-mini-high: 50 messages per week (just like o1, but it seems like these are non-shared limits, so you can have 50 messages per week with o1, run out, and still have 50 messages with o3-mini-high to use)

o3-mini: 150 messages per day

Source for the latter is their press release. They were more vague about o3-mini-high, but people have already tested its limits just by using it, and got the pop-up for 25 messages left after sending 25 messages.

It's nice not to worry about running out of o1 messages now and have a faster model that's mostly as good (potentially better in some areas?). OpenAI really needs to release a middle tier for 30 to $40 though that has the same models as Pro but without infinite usage. I hate not having the smartest model and I don't want to pay $200; there's probably a middle ground where they can make as much or more money from me on a subscription tier that gives limited access to o1-pro.
