It's worthwhile to remember that this is only true of Mythos/Fable and other future models of "similar or higher capability levels" (ant is treating this as a new tier of model above Opus). Anyone who's already been happy using Haiku/Sonnet/Opus on Bedrock will not be affected by this at all.
I don't think anyone currently thinks the Haiku/Sonnet/Opus models are "good enough" such that they would not want improvements. Users may be cost conscious, but almost every task could be done better.
Yes and no. Anthropic controls what is determined to be "similar or higher" and when models are deprecated. Will sonnet 4.7 be "too powerful"? Because once it's released. 4.6's days are numbered.
This created a huge future risk for our org and we're already scheduling meetings over it. Regulated industry, we can't lose control over our data governance or residency controls, let alone the lack of visible audit trails that could reveal customer or PII.
