This makes these models unusable in the settings where people are actually benefiting from these models being on Bedrock (e.g. they have customer contracts that limit who they can share data with, etc).

If the lift from these models is high enough and no alternative springs up, people will find a way to get to yes, but if OpenAI is willing to ship a Fable-class model on Bedrock without this, all the traffic will just move there. I say this because there is not much reason to use Bedrock unless you care about data sharing limits (ok, it seems more reliable than Anthropic's serving, but I don't think that's the major reason).

Of course, they could both decide they don't want the competitive advantage that having an AWS-controlled inference stack brings, but this is basically throwing out that advantage.

Note that this announcement is not just about Mythos, but also Fable, which is restricted from doing any Cyber work in the first place.

Does it, though?

Does Amazon have a clause in their contracts that forbids data sharing with any and all third parties? Is all AWS support and datacenter personnel employed directly by Amazon? Do they seriously have no third-party contractors?

[mrhottakes]

For data on GovCloud and similar deployments, data sharing is indeed restricted and access by AWS support folks is heavily controlled.

Presumably Fable 5 won't be made available on GovCloud Bedrock, right now it's not [1].

However what I'm not seeing discussed anywhere are government agencies that are on commercial AWS, have ATOs in place to use Bedrock, and are now being surprised with this new sharing of data with Anthropic and will have to scramble to disable(?) or institute policies banning Fable 5 usage in Bedrock. Throw in there all your sensitive industries, healthcare, insurance, etc.

Edit: Fable 5 is not FedRAMPed, but it's not clear to me whether or not AWS permits access to it via GovCloud's model request process.

Well, for the services (including Bedrock, but presumably now excluding those particular Anthropic models) that they offer a HIPAA BAA covering, pretty much, if you enter a BAA with them.

Yes. There are all kinds of reasons companies need the guarantee of no training and this is a deal breaker for everyone with such a reason.
