Yes, Astra will have its API price halved while the $200 plan subscribers will have the same usage as before.
There were rumors of a model called "Astra Minor".
I expect they will release this today.
If it performs slightly better than Astra and, considering the subscription cut, is 1/4th the price, it could be competitive with Opus 5.5.
Opus 5.5 appears to be around 1/3rd the price of Astra with a subscription.
