Ever since the Mythos announcement it’s been clear that we’re heading towards a future where SOTA models are no longer available to the average person, and not only cost more, but also require payment in the form of use case verification and data sharing. OpenAI’s 5.5-Cyber model requires the same, so it’s not just Anthropic.
We’re unhappy with this because we’ve all gotten used to being able to play with the new shiny model as soon as it’s available, but what I’m seeing in this thread about Anthropic being “stupid” is emotion-based wishful thinking.
Cool. Everybody is doing it. Doesn’t make it right or make it good for the people. Everyone should complain and help others wake up that Anthropic isn’t the “good guys” like their narrative in Feb/march led so many to believe.
Doesn't Bedrock have the same API token pricing as paying Anthropic direct?
Then stop using AI.
>But I want it all and I want it now.
Spend a trillion dollars and make your own model.
>No fair!
Then petition your government to enact laws around this. Unfortunately the US government rules are currently "Yes, we want AI to take over the world with terminators, just as long as they share data with us".
Do you really expect your government to do anything useful here?
I suppose it’s a reckoning for corporate bullshit about security and compliance.
Have the fancy new, right now, or avoid funneling all your data to third parties. Your choice.
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?
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.
That might work in some countries but Anthropic approach here doesn't fit the legal requirements in the EU.
Almost all companies are content to engage with data sub-processors with respect to customer data or some form of PII.
But there are many that will absolutely not let their IP visit or reside on systems they do not control.
This is absolutely a deal breaker for a ton of organizations and it's not going to trigger industry wide adoption like other comments here suggest. Instead another provider will offer a more appetizing deal and they will win market share.
I am not saying you're wrong, but man that's so crazy. "We have these people whose very jobs are to make sure the company prospers, but we're going to ignore them because hype hype hype". Wild, man.
Sure, but considering the average person and how short-term their thinking tends to be, I'm not sure I'd jump straight into "think about how much money they could lose, of course they think long-term".
Large corporations like Microslop, Google, Meta etc. were frequently behave like headless chickens
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.
As long as it’s service telemetry, not used for model training, not inspected by humans, not analyzed except for service purposes… I don’t see the regulatory issue.
Are there any regulations covering what telemetry your service providers can keep? I’m skeptical, but even if so it would be trivial for Anthropic to exempt certain larger customers while still keeping the policy published as universal.
By definition lots of the use of AI in these companies is gonna require personal data/PII etc (particularly in KYC/compliance or general processing usecases) which means that there's a regulatory constraint.
I personally would've thought that said organisations and regulators would be massively opposed to this for privacy and risk reasons, which is why I think this won't happen.
Even the companies with less sensitive data are generally paranoid about service providers getting "their" (actually their customers) data.
> Are there any regulations covering what telemetry your service providers can keep?
In the EU, this should be proportionate and should avoid special categories of personal data (which FIs will have a lot of).
Their largest clients can negotiate their own deals with their own terms.
They do not have to go through the same public Amazon Bedrock deal that you and I sign up for.

## A new data retention policy
Finally, we’re making a change to the way we handle business
customer data for Fable 5, Mythos 5, and future models with
similar or higher capability levels. We will require 30-day
retention for all traffic on Mythos-class models, on both
first- and third-party surfaces. [...]I'll try to remember to actually try it tomorrow and see what happens.
It's hard to tell how much of what Anthropic are currently saying is just pre-IPO marketing bullshit, or how much will be their long-term policy.
If this is just marketing bullshit ("our models are so powerful we need to keep them chained up at night"), then it does seems massively ill-conceived. I can't think of a better way to break hard-earned customer trust than to say:
1) If we don't like what you're working on - if we think it may complete with ourselves - then we will silently fuck-up the code you're paying us to generate for you
2) Much reduced privacy guarantee. We will now retain everything you send us for an unspecified amount of time while we investigate it
Both of these seem especially self-defeating given that Anthropic has been very successful at courting corporate use, especially coding, and also still seem interested in courting military use.
The silently refusing to comply one (do they just mean deliberately dumbed down, not giving you what you are paying for, or actively sabotaging the generated code?) is really quite extraordinary. Why not just refuse the request? Perhaps they want to claim that gives too much signal as to what they think is valuable, although I think this "recursive self-improvement" story is 100% bullshit trying to juice the IPO. Are they really so arrogant to think that every other company developing LLMs hasn't figured out things like basic development infra?
IMO just the fact that Anthropic think it's in any way acceptable to silently fail requests that might reflect someone else trying to build anything that competes with them is bad enough, but the massive incompetence in what "Fable" is refusing shows that any such decision making is going to be causing them to silently fail a lot more than what they are trying to do.
The Anthropic model names "Mythos", "Fable" seem to have been conceived by a 14-year old thinking that "epic" names will convince people that the model is powerful. It's a bit like putting racing stripes and a loud farting exhaust on your Honda Civic.
It's notable that Anthropic are still using SWEBench as a coding benchmark rather than the newer more difficult DeepSWE which shows them well behind GPT 5.5
Bear in mind that all the marketing efforts such as solving Erdos problem are the result of concerted RL training to impart those narrow capabilities, and how much of any benchmark results, or "early access" paid shill vibe reports, reflect improved performance for more general real-world use cases remains to be seen.
We're an HR startup and likely can't use these models because _we_ have enterprise customers who want zero data retention (ZDR) and have added it to contract language
Shit rolls down hill, as it goes
gpt-5.5 isn't larger than gpt-5.4 but costs double.
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.
