To my feeling, I'm getting usage of Opus (and Fable before the cut) that's greater than what I got from Sonnet last year. I reached $100 of usage when weekly was at 50%. This means, I could squeeze $800 worth of tokens for $20.
Anthropic has sent out a newsletter explaining they were more or less adding 50% (even 100%?) of quota to everyone, due to some great deal they made. That might be it. I do get lots more usage lately.
