The $20 Plus plan still exists, and does not give access to the pro model.
The $200 Pro plan still exists, and does give access to the pro model.
What is new is a $100 Pro plan that does give access to the pro model, with lower usage limits than the $200 Pro plan.
So, reading the tea leaves, they're either losing subscribers for the $200 plan, or they're not following the same hockey stick path of growth they thought they were... maybe?
Edit: I wonder if this is actually compute-bound as the impetus
This is still worse than Anthropic's right? Because you get access to their top model even at the $20 price point
