Mythos is from the same guy who did "GPT-2 is too dangerous to release"

The UK gov disagrees with you:

Bingo.

"We had to do extra work to make this safe because it's so advanced and dangerous..." how many times can they trot out that line before it loses its effect entirely?

It worked for OpenAI when GPT 3 was deemed too dangerous to be released. This is just a spin of that.

Yes, and "in collaboration with the U.S. Government" feels like a very gross ploy at appeal to authority. You don't need Mythos or really any SotA frontier model to make malware or do extensive penetration testing/reconnaissance already. Sure, Mythos might be faster/more efficient, but the cat has been out of the bag for awhile. Even the terminology "infrastructure providers" practically screams "Enterprise leads".

I think all models can find vulnerabilities if read the entire code base. Or intelligently combine parts of the codebase. Especially with test loops.

I know a security researcher at Google with access to Mythos. He says it's the "real deal" and that "there are career plans I had that are no longer viable".

I fear it's a smokescreen to manage cost and capacity.

And to ensure that only USG-approved entities are allowed to secure their code.

I tried 2 chats and it declined both.

- 1st chat asked about a minor shoulder injury most likely mechanisms

- 2nd chat asked about optimal bloodwork testing markers

So the degradation to Opus 4.8 from the article isn't happening in practice?

Oh joy. A model whose safeguards make it prone towards code that make your systems less safe. How brilliant!

DSv4 is nearly in the 2t range, but yes you're generally right

We’ll see it distilled first.

Ah, American Hubris ... I don't blame you, Hollywood is the world's greatest propaganda machinery of all times.

You should check out some Chinese forums. There are services selling gateways/proxies for all major models at fraction of the official rates. Likely reselling subscriptions, or some other form of abuse.

I've seen people posting screenshots of billions of tokens consumed where they paid next to nothing.

These same gateways are likely also reselling the data to Chinese labs, because TLS has to terminate at the gateway level.

Asian labs generated synthetic datasets from UBS labs but also innovated with technology. Now it is harder to get the thinking traces AND Anthropic is recorded to poison it as well.

Thus Asian labs will have to generate their own data sets, which with the huuuuge usage boom from deepseek, mimo, kimi, etc, they will be able to.

That's the reality China already lives in. Their weapon against US companies is commoditizing them, eliminating their moats and their profits by going open weights.

Same thing Meta was doing before they fell behind.

Yeah, because it's impossible. You can't ask it anything about the thing that it's known for. It will not even answer a sky-high level question about reverse engineering, for example.

In CC, it will probably report you to authorities if you ask it to do a vulnerability scan of your codebase.

Not sure this holds, sadly. I spent a few months reporting serious security bugs as model capabilities took off earlier this year, and only ~half were fixed. The unfixed bugs were just as critical as the fixed ones; sometimes they were even two similarly critical bugs at the same company, and only one would be fixed!

On your other point, the government still has systemic leverage and can compel access, so this doesn't remove that risk.

That doesn't mean this is the end of the world, and some balance of power is usually good. But I do think it will still increase the capabilties of rogue actors and their net harm.

I think the Chinese have identified this gap and are working overtime on sovereign inference tech including chips.

That doesn't match my experience at all. I can't see myself saying in 6 months that the current model I am using is useless, that makes no sense.

In fact, I did go back to DeepSeek V4 Flash for most of my problems as it is way cheaper and there is no need to use SOTA for absolutely everything.

People can work around those if they are open-weight.

And, thankfully, I never needed to have a discussion on Chinese politics with LLM in all the myriad of uses I had for it.

Trying asking fable is Israel is committing a genocide

I think the stronger incentive is undermining/undercutting the Western AI companies. Given what we have seen, any model can be used/convinced to do harm so that is just part of the game

A specific strategy is to arm absolutely everyone with very capable models, thus eliminating any advantage the U.S. could get from frontier AI.
