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.

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.

Just an absolute bomb of a release

+1 to other commenters here. * They forced Bedrock for instance to change the existing settings for ZDR / ZOA. It used to be enough to have a default. Now we must set to 'none' and pray it does what it says. * And then there is that BS about "contact your account manager, we will decide account/model retention and sharing individually" Just this creates so much uncertainty that Bedrock has become "glowing in the dark". * We have already moved everything to Gemini on Vertex.

PS: this is what you should see as an error from Bedrock. Anything else is not enough today: "AWS Bedrock Error: An error occurred (ValidationException) when calling the ConverseStream operation: The model returned the following errors: data retention mode 'none' is not available for this model"

It is still adding operational overhead because we now need to vet all models and deny access to any retaining data

Previously it was "use and experiment with anything Bedrock offers--the data stays in AWS so we are not concerned"

So basically all models going forward?

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.
