Yes, I keep hearing that, but I never saw any concrete numbers. That's why I tasked Opus to write a script to keep track of this.

Here's the gist how it works:

The transcripts log the token count, so you can figure out what those tokens would cost in API prices. Each response returns the current 5h and weekly quota percentages, this is what is shown in the statusline. The returned quotas are not stored anywhere by default. So Opus wrote a small script that sits in the status line and records the percentages while I work. Dividing dollars spent by the percent used give what 1% of quota is worth.

On the 20x plan, 1% of weekly limit is worth about $20 in API prices. A full week is then about $2,000, or $8,000 a month. 1% of the 5h window is worth about $5.20.

All of this only works correctly if you use your sub on a single machine, within CC, as chat usage and other machines can not be tracked this way.

I'm on the 20x right now because I got offered 50% off as a returning customer (I cancelled a few months ago). So next billing period I'll switch to the 5x plan and measure its weekly and 5h limits the same way again.
