> For Fable 5, Mythos 5, and future models on Bedrock with similar or higher capability levels, Anthropic will require 30-day retention for all traffic on Mythos-class models. Retaining data for a limited period allows Anthropic to detect patterns of misuse that are not visible from a single exchange. Once you opt into data retention, your data will leave AWS’s data and security boundary.

From the announcement here: https://aws.amazon.com/blogs/aws/anthropic-claude-fable-5-on-aws-mythos-class-capabilities-with-built-in-safeguards-now-available/

> After 30 days, the data is deleted automatically, except in the rare cases where it's part of a safety investigation or we're legally required to keep it.

Pretty sure this doesn't work for any regulated enterprise or government client. But AWS knows this, so I am curious why they'd agree to it.

baq 2 hours ago | parent

> why they'd agree to it

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.

It's the same for girthub copilot [1] which is more present in gov than aws's solutions.

This will fly in EU. As long as the company states the time period for which it will keep data and clean it afterwards, gdpr has no issues with the data retention.

Their carve-outs for safety (public interest) and legal are also valid exceptions in gdpr as well.

Everybody should just assume that they are lying about data retention and learning anyway.

My thesis is that in software you don't want aggregators. They provide the promise of vendor neutrality, but it comes at the expense of increased supply chain compromise risk, small print technically legal data exfiltration.

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.

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.

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.

What is the point then of a submission about how you will be required to share data with Anthropic? I’d say that the point is precisely that it’s an issue when you don’t trust them as much as Amazon.

Qhemlomo 58 minutes ago | parent

Not sure if i follow you tbh.

I only told a commentor why a business would pay more to Amazon than going directly to Anthropic.

The announcement itself is def problematic and either leads to big companies accepting this and then going directly to anthropic or some talks in the background we don't know yet what it will entail.

The security boundary that AWS maintains is important in a lot areas, like medical, where the datacenter has to support some specific certifications. It isn’t a choice to pay 10x more in those cases, it is the only option allowed.

is the 10x the difference between a sub and api token pricing?

UqWBcuFx6NV4r 1 hour ago | parent

I mean, no. Even ignoring the very real benefit (for some) that comes with not needing to trust another party, there are use-cases beyond what you can do with “subscriptions”. Apples and oranges. People just have use cases that aren’t yours.

weberer 1 hour ago | parent

The token price is exactly the same on AWS as it is directly from Anthropic. This is the one service that AWS doesn't charge a huge markup for.

sheeshkebab 47 minutes ago | parent

Pro/max subs are not as flexible as bedrock in api use and don’t seem to run the same models either - often times they are notably dumber (quantized I guess) than bedrock equivalent.

wewewedxfgdf 2 minutes ago | parent

Huh, I felt the inverse.

pridkett 44 minutes ago | parent

There’s a few things mixed up in this comment. But the 10-20x cheaper, I’m assuming comes from the difference between the number of tokens you can use on a $200 Claude Max subscription and the cost of those via the API. That’s neither here nor there for this topic around data retention as Fable has that on all providers.

And for the cost, if you’re an enterprise with more than 150 people, you’re on the token plan.

fp64 16 minutes ago | parent

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!

wewewedxfgdf 4 minutes ago | parent

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

OtherShrezzing 2 hours ago | parent

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.

OpenAI just added their own models to Bedrock recently too, making that an easy switch.

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.”

They give it some thought, but Anthropic and AWS have the whole menu of compliance and security checkboxes needed to reassure CISO it doesn’t need to be “the office of no” and can allow the AI onboarding. The pressure to adopt and adapt to AI is so high right now that there’s nothing a CISO or CFO can say to stop its adoption. And the more they say “no” or “wait,” the more at-risk they put their job.

In theory, definitely.

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 regulator sign-off, which almost certainly won't be forthcoming.

Like, if the Fed and the ECB say this is OK then it might work, but other than that I predict that this decision will be reversed ~soon.

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.

That Claude support page says the exact same thing about AWS (“retained data stays in your AWS environment”). AWS’s docs say differently, though, so it seems one of them has incorrect documentation. I wouldn’t necessarily trust the Claude docs to be correct even regarding GCP until some of this is ironed out.

edit: Google’s own docs also say zero data retention isn’t possible with Fable and your data will be retained for 60 days “outside of your account”. I’m doubtful that this data sharing is an AWS-only thing.

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.
