I've been brewing on this topic since Mythos preview was announced. As Mythos got finally released, then banned, then released again under U.S. government control, it was time to finally flesh it out and use it as a way to exit the lurker-zone on HN !

But what if Opus 7.1 is real smart - as what Mythos was promised to be?
Or an Opus 9.0
Will Cybersecurity ever start to be an issue?

This is a great read! I never realized the scale of the effort to find that BSD vulnerability- helps put things in perspective

So funny both this and https://news.ycombinator.com/item?id=48698617 are on the front page at the same time.

The fear porn around this all has been horrible. I work in Cybersecurity and Mythos is all the vendors will talk about because they want to sell something. It started the day of the announcement which is what told me it was all BS. They had no information about it yet would happily tell me about all their solutions for it.
Anyone in my profession worth a damn will tell you the vast majority of security issues are related to bad configurations and bad practices + accidents and bad luck. Vulnerable software is a problem but basic defense in depth will either mitigate or drastically reduce attack surface. Mythos does nothing to change that.
The technical debt at companies is the largest security threat. That, and layer 8 which is the people factor. The amount of silliness I've seen from people and companies as a whole is truly hard to verbalize. I've seen banks that gave every employee from the janitor up to the CEO domain admin access due to a crappy application that was written in 2004 that they never updated. I've seen a fortune 250 company write its own internal routing protocol that was basically clear text traffic that dated back to the 1990's and was never retired because, why not. I've seen contractors infect entire fab's in the chip industry because they plugged an infected USB stick into a 30 year old tool that hadn't seen an update in over 20. Then when the fab came back up, they did it again the next day.
Ultimately, Mythos is just another tool in the toolbox. It's great to find new vulns but it is incredibly short sighted to think it will move the needle in any meaningful way in the security industry.

it all looks suspicious:
```
  - June 1st 2026: Anthropic files S-1 paperwork with SEC to get ready for IPO

  - June 2nd 2026: Anthropic annouces expanding "Project Glasswing" to let people use their new model to enhance security of existing systems

  - June 9th 2026: Anthropic releases Mythos model

  - June 12th 2026: Model gets export regulations placed on it by US Gov

  - June 26th 2026: US gov announces they will let some companies use new model

  - August 2026: Anthropic goes IPO
```
The timing of all of this just seems to be a play to pump the stock. The reality is that in six months GLM-5.3 will be released open source with comparable functionality to their Mythos model. They are trying to cash in before that happens.
I would not be surprised if the US government, the people pulling the strings who actually put the export announcements onto Anthropic, actually have purchased stock in the company to artificially pump up the stock, I would bet money on it.

The actual story here: The Trump administration is going to choose which organizations get access to which AI models when.
This will establish an asymmetry where the chosen organizations get to secure their stuff and break other people’s systems with each new model release.
If you believe the “good guys” will be the ones given asymmetric offensive access, then you’re either severely misinformed or support things like ethnic cleansing (which these models are already being used for).
Mythos’ slightly higher performance is a nothing burger. It is not even the current top model. According to anthropic, gpt 5.5 is!
Personally, I’m switching to open weight models asap, and probably will start sending money to Chinese vendors since they have values more compatible with western democracy.
