It took me a while to figure this out too and only did in the last couple days: a 10x, 20x, or 25x plan is the cost of your monthly sub times that multiplier in terms of API costs.
So a 20x plan, that was formerly $200, would have been $4000 in API credits. Which sounds like a lot but the API is absolutely horrendously expensive - like you'll burn through $100 in 45 minutes of 5.6 Sol on High reasoning. I know this because I did this once.
They still used multipliers in the email. The relevant passage was:
Starting October 30, 2026, your included usage in ChatGPT Work and Codex will decrease from 20 times to 10 times the ChatGPT Plus allowance. Your GPT-6 Pro limit in Chat will decrease from 200 to 100 messages per week. Your price remains unchanged and you’ll keep your current limits through October 29, 2026.
And:
For those who want even more usage and speed, the new Pro 500 tier offers our highest usage allowance, with 25 times the usage of Plus. It also includes access to Ultrafast, with up to 8 times faster token generation.

Does anyone see the usage limits? I don't see anything indicating how much usage is in each tier.

I don't see any of those terms. Not even on the signed in page to upgrade to to a different Pro plan.
The plans I see are labeled, "Pro 100", "Pro 200", and "Pro 500" with the number corresponding to the price in USD.
