This is odd behaviour, and provides some evidence that Anthropic isn't being managed by serious people. With this policy across AWS/GH/Zed/etc, they're taking their massive lead in enterprise/govt sales and handing it to any competitor who can serve a model anywhere near these capabilities with a modestly nice UI.

I mean, they were already capacity constrained and just introduced a larger model that takes more capacity to run... They were gonna have to hand some business to competitor one way or another.

I am willing to bet that the SpaceX deal is probably why Fable's launching now, as they are much less compute constrained than they were a month ago.

It looks like they’ve been preparing: https://www.aboutamazon.com/news/aws/bedrock-openai-models

That's different though. Anthropic want everything for 30 days, not just flagged prompts/interactions.

Let’s be real, chances are that the people with a lot of money on the line have given it more thought than the passing thought that you gave this comment.

You've mistaken "a lot of money" with "intelligence." Which is why I think the AI crowd really really wants this magical machine god thing to succeed. Then they can really have money = intelligence whilst keeping the rest of us poor and stupid. You know, like how they used to prevent literacy among the slaves.

Because they didn't store data before? Don't be so naive.

Zero data retention was an enterprise agreement that Anthropic and Amazon agreed with customers and delivered on. There’s no way AWS would trade in their reputation with enterprises just to soak up some slop.

Also broadly available to us plebs via openrouter and similar. Claude is available on there under ZDR terms via the Google Vertex and Amazon Bedrock providers.

Is it a larger model or just better trained? Anthropic does not actually claim it is a larger model anywhere that I can see.

If it’s not larger, it’d be tough to justify the massive price increase for using it.

But this seems like a really, really, really no-good seriously bad decision from Anthropic. Like, I get why they want this (and can see it from their perspective), but many of their largest clients literally cannot allow this without regula…

Bedrock doesn't offer zero data retention for OpenAI's latest models either > For OpenAI GPT-5.4 and GPT-5.5, classifier-flagged traffic will be retained for up to 30 days for automated offline abuse detection https://docs.aws.amazon.com/bedrock/latest/userguide/abuse-d...

I think that’s by AWS though. For Fable you need to flip an account wide flag that says “I want to share my prompts with the model vendor.”

The Fable announcement page on the Anthropic site says this data sharing will be applied regardless of the sharing setting of the company account.

Note that if you use AWS Bedrock then you're choosing to pay 10X to 20X because you trust AWS more than Anthropic. It is literally 10X to 20-X cheaper to directly buy Anthropic subscriptions for your devs.

I can't use "Claude Max" subscription and the likes with my own software, can I? Using OpenCode instead of ClaudeCode violates the ToS, doesn't it? How would I go about permissions and integrating with my other services I already run on AWS? IAM roles for Bedrock are pretty nice. You appear very confident and concerned about my spending, so please help me here!

I grant you the right to spend 10X to 20X on Bedrock. Use it wisely.

Ugh. I'm sure we're not the only company that's going to face the difficult decision to either stay with Opus 4.8, switch to a different model provider or update and significantly weaken our terms of service around no model re-training, not sending data to third parties and the like. I understand why Anthropic wants to do this but I'd be much more comfortable with it if the data never made it to Anthropic unless an analysis Amazon ran, maybe even using tools from Anthropic, determined that there was something to look at. That'd be an easier carve out in an enterprise Terms Of Service / Privacy Policy.
