Anthropic requires 30 day data retention for Fable and Mythos (support.claude.com)

It is actually worse than that. It is at least 30 days. There is an "almost" that is doing a ton of heavy lifting here "deletion after 30 days in almost all cases". My read of that is they can hang onto data for as long as they want, even if they usually won't. And "all traffic" with an agentic harness is basically your entire codebase you work on.
> We will require 30-day retention for all traffic on Mythos-class models, on both first- and third-party surfaces. We won’t use this data to train new Claude models, or for any non-safety-related purpose, and we’ve instituted new privacy protections including logging all human access to the data and ensuring its deletion after 30 days in almost all cases (see this post for further details). The data will help us defend against complex and novel attacks (including new jailbreaks and attacks that operate across many requests) as well as help us identify and reduce false positives.

They seemed to have changed the wording since you posted the comment, now specifying exactly 30 days with seemingly no exceptions.
These terms seem to be updated at-will, so I'll take that with a grain of salt however.

I'm not sure they can actually respect that 30 days absolute commitment. Let's say some internal tool flags a suspect conversation, it bubbles up and a human operator reads it and it looks like evidence of a crime. Then, that employee is legally bound in many jurisdictions to prevent the destruction of that piece of evidence.
It's one thing to commit to a "everything is deleted when you press delete" automatic policy. It's quite another to say "we'll keep some stuff for up to 30 days, look inside it for any malfeasance, then pinky promise we'll delete it".

Yep. They changed the terms, which needs legal review in my org, but the Fable model was available immediately, so of COURSE people have to go and flock to it to see how much better it is. Amazing how easy it is to spend five figures on demand and have very little to show for it; meanwhile when I want to buy a piece of enterprise software for 40-50k/year I have to spend weeks or months building the case, providing justification for ROI etc.

This reads to me as they can use any model that is not a "Claude model", and as for human access to that other model there can be different less restrictive privacy protections. In other words, that anything goes.

One of the major attack vectors is distillation, where millions of questions are auto-generated and coordinated to produce training data for new LLMs. Anthropic alleges Minimax, Deepseek and Kimi were trained this way. Deepseek 4 compares favorably to Opus, so they're probably trying to prevent Deepseek 5 from being a bootleg Mythos. https://www.anthropic.com/news/detecting-and-preventing-dist...

Even worse when you git push something Microsoft gets all your code!
dannyw 17 hours ago
Yes, that is your intended purpose of “git push”, it’s to save. And only if you use GitHub.
A better analogy here is probably “every time you use VS Code, the files you edit get sent to Microsoft”.
Some legitimate concerns:
• You have trade secrets. Previously; you can use services like Bedrock, etc, with signed contracts and significant reputations. Your contract is between AWS and you, and stays within your AWS security boundary.
• Security breaches. Remember when Anthropic accidentally published the source tree of Claude code? Or Meta’s recent AI recovery bot that didn’t check if the supplied recovery email was actually the email of the Instagram account? The best way to reduce your exposure is to minimise storage.
• Weaponised T&S. For example what if Anthropic decided to build a classifier for “usage in unsupported regions” that’s super overbearing (as we see with Fable) and vacuums up all context/input/output if there’s Mandarin? Contractually they could now retain it forever, not just 30 days, for ‘trust and safety purposes’ and perhaps have AI scan for any new or interesting ML techniques at scale, for Anthropic’s own use? They say just can’t train Claude models on the data.

people over-rate how much software/IP is useful in running a successful business. There are genuinely very few IP in this world that needs to be protected. Everyone else is running stupid CRUD apps
They also over index fear of LargeCo stealing IP from SmallCo. In fact, LargeCo is typically more scared about even the possibility of any product team looking at competitor internals due to lawsuits.
59nadir 10 hours ago
I've worked with a company that literally has a one-of-a-kind product that is the single product in its niche that uses a very specific and custom algorithm to run its workload 500-1000 times faster than the competition. Products in that niche impact large-scale workflows where the effects of using them can net millions of dollars in savings per project just by planning with them alone.
I learned after my contract with them was put on hold that the CEO uses Claude to vibecode experiments on the code base. Not for any good reason, mind you, the algorithm was written by the CTO who emphatically does not use any LLMs.
With Anthropic's reach they could probably make a massively successful product in that market and basically take the entire thing over, if they only knew to look. And I'm 100% certain that they don't actually follow any policies on not using their incoming data.

Don't get me wrong, you need the right background to understand it and that's not trivial, but if you got someone from the right area you could replicate it pretty easily.
Eridrus 12 hours ago
In general, I agree with you.
However, in the case of model providers, I think it is a more real concern since it could make it into some training data, and then one of your actual competitors could ask the model to code something up and get your IP.
I sort of assume the frontier AI labs are good about not doing this when they promise not to, but if you don't have airtight restrictions on what your devs are doing, they might be sending it somewhere that hasn't agreed....

This is massive and an insane move from Anthropic. They should have worked with AWS to have the retention done entirely in AWS infra and disabled the retention on their side.

Exactly. See my downthread comment. That is my proposal as well.

I would be fine with that.

consumer451 6 hours ago
Yeah sure, maybe, but prior to this, the model creator had no observability into any of this on Azure/Bedrock, right? Now they do. That's one over-eager PM or bug away from training on my clients' data.
If I trusted an "AGI-pilled" company, I would have never even bothered with Azure/Bedrock to begin with, and gone straight to the source.
AGI-pilled means that you think you are building god. They might actually be doing that, but in either case, I cannot trust people in that state of mind with my clients' most valued proprietary data.
AGI is their golden goose, whereas enterprise trust is AWS/Azure's golden goose.
edit after upvotes: I get it from the Anthropic POV. I am not an Anthropic hater, in-fact I am a huge fan. People trying to distil their models would likely use Azure/Bedrock for that purpose, as the lack of Anthropic observability would be ideal for that. Still, this all sucks for anyone building an honest business with enterprise customers.
There has to be a better way. Maybe deploy the automated observability tools to the Azure/Bedrock teams... and have them flag and investigate accounts? If Anthropic can do this, so can Azure Foundry/Bedrock teams, right? Maybe even forward deployed Anthropic folks would be ideal to keep them honest, as long as the raw data does not flow back.

am I correct that you basically cannot comply with HIPAA in this case, even if you had a BAA with Anthropic?
I'm new to the whole governance / compliance thing and wondering like even if you use a HIPAA compliant tool like Bedrock to serve up your inference in your VPC, this sort of puts you in a dangerous legal spot?
it seems like the data retention, even if it's metadata and they promise not to log the actual full logline, messes you up here since it's leaving your autonomous system
Also what about things like GH copilot using an anthropic model as the backend? This feels like a mess with chained data agreements

buzer 16 hours ago
Mentioned in the earlier, topic as well, but one very important point here is that it looks like Anthropic is becoming GDPR controller for all submitted data for this model (when they are in GDPR scope anyway). So data subjects would have Article 15 right to request information about processing and possibly a copy of the data. Latter might be contested under "rights of others", but former is more absolute.
What this means it that if someone makes an Article 15 request, they would be entitled to know if Anthropic holds personal data about them and also from who they received this data at minimum.
If someone wants to do that, I would recommend combining it with Article 18 request to forbid deleting the data for legal claim in case you contest Anthropic's reply. Otherwise they could just delete the data per their retention policy and DPA would find much later that they no longer hold the data.
Another issue here is that their DPA frames everything as controller-to-processor, i.e. they do not appear to have SCCs in place to actually receive this personal data as controller. So the original exporter would likely also be in breach if they send any GDPR covered personal data to this model.

You have right to ask for it, but it doesn't guarantee that they will do it. It's also limited to data they hold as controller (i.e. the copy they hold for "safety" purposes), not the original copy that is controlled by customer. For that you will need to contact the source.

I guess the better question would be if you are under and NDA and using an online model, are you already violating it but does this violate it further?

In the same way that using Gmail and Dropbox and iCloud and Notion violates it. (Which IANAL but for most NDAs would be not at all.)

Google Workspaces and Dropbox have an IL5-compliant offering, which means they attest that they will not do exactly this (and are audited on that). Not sure about iCloud and Notion.

I got off from all anthropic stuff a while back. And I feel the fresh air again. No bloated reasoning or code. No vendor lock-in (due to complexity increase in code). Money saved too. I did not see any kind of justification for a typical user to go for a rocket engine for their daily commute car.

Anthropic is desperate for the IPO and will release a half-baked product that they are so afraid to release, you can literally feel the shiver through the text of their press-release.
Now they want to have any way of either fixing it, or in case someone will actually make a big boo-boo with their model, to be able to blame the guy in the end.

Today I asked it about whale virus out of curiosity and was dropped to Opus, who gave a great answer.
They are for sure not using mythos or opus do the safeguard check.
moritzschultz 9 hours ago
As far as I remember OpenAI does it too even when using the API. Their reason is fraud and harmful behaviour detection. But let's be honest, does it really matter? Building a successful product does depend on so much more than the technical implementation and brainstorming you do with Fable, Mythos or any model.

Worth noting retention doesn't end at the model provider. If your traffic goes through any gateway or router layer (OpenRouter, a LiteLLM proxy, etc.) that layer sees every prompt too,

Didn’t they all but admit they’ve been storing and actively looking at requests with this post: https://www.anthropic.com/news/detecting-and-preventing-dist... ?
If they weren’t storing, they’d be oblivious to what customers are doing, making this kind of detection impossible. What data did they train their classifier on, if not real user (distiller) traffic?
cowsandmilk 15 hours ago
Why can’t they have trained the classifier on internal red teaming?
crazylogger 14 hours ago
They basically said "Deepseek ran 150,000 requests and here's the gist of one of their prompts". Anthropic doesn't know which accounts are Deepseek proxies beforehand, so definitely sounds like retrospective analysis of broad user logs to me.
Of course Anthropic realizes saying this straight is problematic so they said they examined request metadata, but no, I don't think they can get this kind of insight from metadata (token counts, request time, etc.)

After the AI companies just blatanty lying that they weren't hoovering up people's IP and art for training I assume they collect any and all data they can get their hands on for training. When it comes to the big AI players feeding their future models I 100% just assume that they suck up any data we send them. Am I cynical?
lawrjone 2 hours ago
Most companies have legal agreements called "Zero Data Retention" with these providers that bans them from storing any data that you send them (we are one of those companies).
The difference here is that for the first time Anthropic have said that's not available for 'Mythos class' models.
indoordin0saur 2 hours ago
Sure. That's what they say but does anyone actually trust what they say about where they are getting their data? They also had a legal requirement not to steal IP, they said they weren't and then it came out that both OpenAI and Anthropic were pirating mass amounts of media. When they said they weren't doing this they were knowingly lying. I'm quite certain that some (if not all big players) are retaining data from their customers despite explicit agreements not to do so. As a data engineer myself, I know how easy this is to do.

I think this was the most sensible way to deploy this model. Considering how much of a step up it has been from Opus.
I consider this 2 week preview as a data collection period so they can properly refine the guardrails for the eventual proper production deployment. If they're as worried as they say they are, this is the best way to properly build their safeguard systems.
It's annoying af, but I'd rather be cautious here.

There were two (expensive) exceptions / alternatives so far: Bedrock and Vertex. Their Zero Data Retention was in fact contractually enforced. Now it is all f...d because of these morons at Anthropic. For now I am better off just using DS via their API.
This is just a tragic moment for Tech. We just killed AI privacy. OpenAI already follows this trend and others will do too.

This could be a big issue for firms with strict GDPR criteria: "This change only applies to organizations that have set up workspaces with zero data retention (ZDR) in Claude Console, use Claude Code with ZDR in Claude Enterprise, or access Claude through AWS Bedrock, Google Cloud Agent Platform, or Microsoft Foundry with ZDR. The rest of this article applies only to these organizations."
pbgcp2026 18 hours ago
All I can say to my team (and my clients): "f...k Anthropic". They've just put both Bedrock and Vertex on slippery slope of "we don't collect your prompts. period. ... comma ... except ..."
Right now we have changed the code of all our agents to data retention mode 'none' (Note: not "default" or "inherited", this is not enough now!) and we are fighting with GCP doco to set similar things for Vertex.
This is just terrible.

Maybe this isn't different than using something like Google Sheets to keep a list of people to dox and blackmail, but the leverage certainly makes it feel different.

I mean not just the part 30 days data retention but I think the serious trade of this product is just the token efficiency. They trade it for precision. The claims that they make that it found a 30 year software bug from millions of lines of code is just precision. To human it's looks like a lot but for it it's just the ablity to process (token processing). Let's see how long it runs. Peace.
