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 mo…

Does anyone know about the jailbreaks and attacks they are referring to? These are done through model queries?

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...

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.

Reminder: FISA Section 702, aka FAA702, aka PRISM, aka the #1 most used collection source by the US IC, allows *warrantless* realtime access for the US federal government to everything Anthropic, OpenAI, Google, Apple, Microsoft, Amazon, and Meta have on you.

It takes a lot of audacity to train on all the data you can without any license, attribution, etc and then act like you can own the outputs of the model so that someone else doesn't make a model from your data without a license. I've lost a lot of respect for Anthropic in the last 24 hours.

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!

A Startup using gitlab or github or bitbucket also have the same risk right?

Pretty incredible just how much good will Anthropic managed to burn.

Are they really burning good will? For many users this is a deal breaker. But for the general public, politicians, etc they’re stamping “safety” on their brand.

Can’t wait till that turns into “regulatory capture”

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?

Why can’t they have trained the classifier on internal red teaming?

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.)

It’s even worse than that. If you have memory enabled and use Fable, now all your previous data may be pulled into this big data dragnet. How can Anthropic possibly think this is okay?
