I had a great run in the first decade of iOS development. Not so much since.
I had 180k downloaded units in the last year - but I'm excluded from foundation models because I did well before 2015.
That seems like an odd policy. Apart from anything else - it explicitly punishes long-term accounts...
Lifetime downloads...
As @rickystone mentioned, using the on-device Foundation Models (SystemLanguageModel) doesn't have any limit, but the access to Apple's Private Cloud Compute (PCC) is only available to developers who meet some criteria, as detailed in Accessing Private Cloud Compute.
In the case where your app has more than 2 million first-time app downloads in long time span, and hence has no access to PCC, I’d suggest that you file a feedback report – If you do so, please share your report ID here for folks to track. Thanks.
Best,
