I'm paying $90(?) a month for the Max and it holds up for about an hour or so of in depth coding before it kicks in the 5-hour window lockout (so effectively about 4 hours of time when I can't run it). Kinda frustrating, even with efficient prompt and context length conservation techniques. I'm going to test this new sonnet 4.5, now but it'll probably be just as quick to gobble my credits.
I'm on a max ($200) plan and I only use opus and I've _never_ hit a rate limit. Definitely using for 5+ hours at a time multiple days per week.
You have got to have some extremely large files or something. Even with only Opus, running into the limits with the Max subscription is almost impossible unless you really try.
