GPT 5.5 does not have the same capabilities as Mythos. There is a separate 5.5-Cyber model which is the Mythos “equivalent”, but it is similarly restricted access like Mythos. Per OpenAI, the major difference is the built-in safeguards that 5.5 (and other models have), where 5.5-Cyber does not have these safeguards and is more “permissive” for security work.

I have access to the Cyber version. It’s great at cybersecurity work but only marginally better than its predecessor with the right jailbreaking.

I imagine Mythos is going to be the same story from what I’ve seen so far.

That reminds me:

I got cajoled the other day that I need to upload my ID and ask for 5.5-Cyber access by the Codex desktop app while I was having it develop a fuzzing suite for an open source library I'm(we?) are developing. I was able to berate it into getting back to work.

This struck me as a point of emergent enshittification; an anus if you will.

reply
The company doing the actual ID verification (KYC) is probably the last company I'd trust with this kind of data.

To circumvent conversations being flagged as "cybersecurity bad!!!" I often have to use previous models (5.3 for example, and sometimes using them through subagents is enough). And when this method no longer works, local models will be good enough for it to not be a problem (for my use case, at least).

reply
That is very clearly the claim of mythos though. The experience of projects that do have access to mythos though suggests that if you use the other models it's not going to find much of anything. Which is to say generally we believe it is marketing as you say however the claim that the reporter said is very clearly stated even if it's not right.

Immediate distrust of the article… The author might be parroting company marketing, unable to discern that a lot of this is much less complex than it seems.

I have also worked at Reuters and National Journal, where I began my career in Washington chronicling congressional efforts to reform surveillance practices at the N.S.A. in the wake of the 2013 Edward Snowden disclosures.

What have you done lately?

Your comment was surely well meant, but you could have plainly stated that the article author is a seasoned reporter instead of the snarky reply.

GP might be incorrect in stating that the author is parroting Anthropic's marketing, but the author certainly does not go out of his way to specify that these are only Anthropic's claims. It is actually a bit ironic as the article linked[0] from the quoted part (by another author) uses the correct phrasing when dealing with such claims:

> Anthropic, the artificial intelligence company that recently fought the Pentagon over the use of its technology, has built a new A.I. model that it claims is too powerful to be released to the public.

I feel like this website is a particularly dangerous place to ask that and hope it to be a “mic drop” moment. There are a lot of highly accomplished engineers, scientists, founders CEOs, etc. here that could easily respond to that with any manner of impressive qualifications.

Lately I’ve been trying to think critically. I am not perfect, but I can recognize appeal to authority from a mile away.

> An argument from authority (Latin: argumentum ab auctoritate, also called an appeal to authority, or argumentum ad verecundiam) is a form of argument in which the opinion of an authority figure (or figures) is used as evidence to support an argument. The argument from authority is often considered a logical fallacy and obtaining knowledge in this way is fallible.

reply
> there is disagreement on the general extent to which it is fallible - historically, opinion on the appeal to authority has been divided: it is listed as a non-fallacious argument as often as a fallacious argument

> Some consider it a practical and sound way of obtaining knowledge that is generally likely to be correct when the authority is real, pertinent, and universally accepted

Anyway, other than trying to think critically, anything?

Reporting on such stuff requires networking skills, not technical knowledge.

Okay, well I’ve done more than that and I say he’s right. Now what?

nytimes reporters have recently been very disappoiting and starting to feel like they're people who managed to become relevant long time ago, but haven't kept up with recent changes and are just parroting things others have said instead of unique thoughts.

I found their recent investigative article on How do stars pee at the Met Gala? to be hard-hitting, yet fair to all sides. [1]

Not at all.

OP posited that the author didn't know what he's talking about. I pointed out that the author has far more knowledge and experience in the field than rando internet griefers on HN who immediately reach for "shoot the messenger" when they read something that doesn't neatly fit into their pre-conceived worldview, instead of perhaps learning things from other people.

But at least your trope acknowledges that he's an authority on the subject.

You mean, you guessed that a random person online lacked experience. The experts are genuinely here too.

reply

That position does not appear to be present.

Eh, "unable to discern" seems like a polite way of saying someone is talking out of their ass.
