AWS Bedrock to require sharing data with Anthropic for Mythos and future models - https://news.ycombinator.com/item?id=48473166 - June 2026 (223 comments)

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.

How were they not already auditing access to customer data?
codebje•35m ago
They were not keeping it beyond the timeframe necessary for the model to process it, so there wasn't access there to audit.

Step 1: Find all companies which refuses/bans to use SOTA models from irrational fear.

Step 2: Use SOTA models to copy them and crush them

Step 3: Profit.

(Yes, not every business is easily replicable, but you sure can find some)

applfanboysbgon•47m ago
Can you name a single example of a business that has been replaced by another business leveraging LLMs to copy and "crush" their software?
pbgcp2026•37m ago
Pretty much any Chinese business. (Except takeouts and laundries)

Step 4, get sued because you violated an NDA or other regulation?
ai-x•23m ago
thekevan•1h ago
So if you are under an NDA, does this violate it?

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?

FiloSottile•1h ago
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.)
layer8•47m ago
I never had an NDA permit such usage.
FiloSottile•43m ago
Your NDAs prohibit emailing a colleague about the e.g. project, or discussing it in a Slack DM with the client, or tracking progress on it in JIRA? You have to do NDA’d work exclusively with local tools or end-to-end encryption? Those are some difficult NDAs!
layer8•26m ago
We use inhouse on-premises email, issue tracking, and messaging. Depending on the project, external communication does require E2EE email. Development happens on local hardware and software unless required otherwise by the customer.
FiloSottile•5m ago
I’m pretty sure (even just based on the revenue of various SaaS products) that’s not typical, hence “most NDAs”. I’m also sure some require a SCIF, but that’s not most of them.
lvl155•1h ago
I actually think that’s warranted. And if you used it to poke around, you would also agree.
unshavedyak•51m ago
> And if you used it to poke around, you would also agree.

Would you elaborate? Not sure what you're describing

connorboyle•1h ago
A startup that uses agentic coding tools such as Claude Code or Codex is packaging up their entire codebase and sending it directly to their LM provider. Depending on their product, they might be sending it directly to a potential competitor.

Odd times we are living in!

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.

hnlmorg•1h ago
I’d be more scared of a data leak due to LargeCo being hacked than I would about LargeCo prying into the data.

What I don’t trust LargeCo with is personal information. I’ve heard too many horror stories about Govs and LargeCos swapping customer nudes or stalking ex’s to be comfortable with anything personal on those systems. But that’s a whole different topic.

keithnz•1h ago
the real risk is using it at all as you are already sending them your data. If you are ok with that, then this retention/review seems ok.
Daedren•43m ago
From a personal use perspective yes, the big issue here is enterprise and existing contracts as surely most companies will have signed zero retention.
pbgcp2026•39m ago
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.

The only hope now is ... tada .. Mistral LOL

osti•23m ago
Hmmm no? The only way is to deploy your own local model, using anyone else's you are at their whim on what happens to your data.
Sol-•52m ago
Fortunately I can't use Fable anyway, since their hyperactive content flaggers do not let you work on anything remotely biological or medical related (i.e. parse a CSV with some medical content, nope, you're probably a bioterrorist) and you get downgraded to Opus immediately.
pbgcp2026•43m ago
Yes! I have hit the same brick wall. What sort of idiots are doing this? Honestly, I have no idea. And just before their IPO. SO far Anthropic marketing has been perfect and spotless. This is serious slipup.
solenoid0937•29m ago
It's good they're being overcautious here. The alternative is far worse.

torginus•2m ago
My 2 cents is that doctors people with lots of money and very specific needs who generally don't really go for tech jobs, so they're probably planning to create a separate monetization tier.

That, or alternatively, Mythos is so good at medical stuff, that it cam replace a lot of physician work 90% of the time, pissing off doctors, while the remaining 10% would result in very expensive lawsuits.

pbgcp2026•47m 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.

Vortex777•35m ago
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.
zb3•26m ago
What an annoying company, I wish it didn't exist..
giancarlostoro•12m ago
Yeah I'm never using either one, and if that becomes standard Anthropic will never see a dime from me again. I'm going to draw the line in the sand right there.
I'm not talking about Claude copying.

I'm talking about scouring Twitter/LinkedIn and look at posts from employees who say SOTA model is banned. Look at what the business do. Copy it using SOTA. Call their clients with 30% discount and faster turnaround and higher quality product.

It is complicated, but I can get Private Equity of even VCs to fund this idea.

tl;dr -- I'm actually agreeing with you. Anthropic will never copy your business model due to NDA. But there are plenty of fearmongering about they copying you and because of which you won't use their models. If their models are genuinely SOTA you can use that information to your advantage and crush scaredy-cats.

pbgcp2026•37m ago
This. And AI labs seem to be above IP / Copyright law and absolutely nothing will happen to them when they grab all the data and package it up.

LargeCo is probably struggling under the weight of technical debt and organizational challenges/politics.

I bet if you gave them the Codebase of the Gods, it’d be a heap of hacks inside a couple months.

Yes, it certainly is an odd situation when some people believe you cannot use Mythos-class models because security while others believe you must do code reviews with Mythos-class models because security.
