No. If you want use Claude anything serious, you will need the 200/month subscription. I have tried them all and you will run out of Opus too quickly with the lesser ones on a daily basis.

I have the opposite experience (although with sonnet) - I have to recklessly instruct Claude to make super verbose tool calls to even get close to chewing through enough tokens to use up limit before the 5 hour reset period or whatever it is. I don’t find enough performance increase w opus to justify it.

I ran out of Opus this week in 2-3 hour of use with the 100/month sub. It was not particularly heavy use, either.
