I have the $100 plan and now quickly get downgraded to Sonnet. But so far have not hit any other limits. I use it more on the weekends over several hours, so lets see what this weekend has in store.
I suspected that something like this might happen, where the demand will outstrip the supply and squeeze small players out. I still think demand is in its infancy and that many of us will be forced to pay a lot more. Unless of course there are breakthroughs. At work I recently switched to non-reasoning models because I find I get more work done and the quality is good enough. The queue to use Sonnet 3.7 and 4.0 is too long. Maybe the tools will improve reduce token count, e.g. a token reducing step (and maybe this already exists).
You are using the "auto-switch back to Sonnet" mode right? Try just selecting Opus without the auto-switch, probably you'll get more Opus and may not run out of it. Anthropic is just being careful because Opus eats compute and they don't want people getting disappointed. But for me it does not run out that quickly. Only when I asked it to work on a 50k+ source code file, which it had to ingest entirely in my case, is when I ran out.
Also there's likely only so much fixed compute available, and it might be getting re allcoated for other uses behind the scene from time to time as more compute arrives.
