So basically all your data will flow to NSA/CIA/Mossad if they show even slight interest in your org or you as a person. Gotcha.
Even in the happy case where nothing bad happens, you get a badly integrated product, because you integrate not against the actual vendor, but against a abstraction layer that commoditizes the actual product, effectively forcing you to either use the least common denominator of features, or circumventing the actual aggregation model itself with some kind of 'vendor_specific_parameters' parameter in the aggregator API.
My thesis is drop the vendor neutrality, and build your integration with the vendor directly.

Do we believe that?

Aha - so, data is forever.
If you don't believe them now why would you have believed them earlier when they said "no data is retained" ?

that's obvious, but perhaps worth stating: it's worth it, demand for the model is unprecedented and the only downside for Anthropic if AWS rejected would be some revenue pushed a quarter away as they get Fable ready on their recently acquired compute from xAI and Google.
