As a ChatGPT Plus tier subscriber (ie comprising only me & ChatGPT as a standalone chatbot, is my plan’s usage limit using model 4o as of March 6 2025 the same as it was originally announced in mid-2024: 40 messages per rolling 3hr window, right?
A) If so, is my usage limit any different using model 4.5?
B) OR are 4.5’s usage limits stricter than 4o’s for Plus tier subscribers such that-even if my ChatGPT activity level stays completely stables & rises no higher as I migrate from 4o to 4.5–I’d nonetheless reach 4.5’s usage limit much more frequently?
