From a cost perspective Mythos is too expensive right now. With the right Harness and a few layers of models you can get close or better in some circumstances. Kimi / GLM, Qwen etc. And that's before ablation / Abliteration...
For those in Mythos.. if you ask how much it cost to assess their repos, your jaw would drop. We're talking the price of buying a couple machines to run Kimi / GLM full weight outright.. for one Scan.
I’ve been working on a decompilation project that fable was choking on and GLM 5.3 has been chunking away at it for 72 hours now? I think it’s my favorite agentic/implementer model right now.
may have been rushed by hugging face being unable to use claude to debug or fix their breach, because there isnt detail on new guardrails put into place to protect against anthropic's initial concerns of wide distribution?
separately, it is interesting they are adding an oem type offer:
>We’re working with our cybersecurity technology and services partners to integrate Claude Mythos 5 into the products and services defenders already use to secure their software.
anyone know the shape of those contracts, e.g. pure tokens/usage or more of a traditional licensing or oem type structure?
This week I found two issues in my company codebase. After finding them I told a claude session about one and asked for a quick proof of concept demo of the exploit. It refused, including refusing simple things in the same session afterwards.
Meanwhile same model in a new tab, say I need help creating a page that hits an endpoint with a special payload and it does the same things that were too dangerous in the previous tab...
> Bringing the cybersecurity capabilities of Claude Mythos 5 to more defenders
This dance is quite annoying. If Anthropic release a paid model, the user should control what it does and doesn't do. The other day I had a security incident that required urgent response. ChatGPT and Claude were utterly useless (I quickly attempted to get access to the former's advanced security capabilities but was met with a form I could complete - far too slow for a time-sensitive problem like a security incident!). So I used grok and it helped! I am told Kimi also helps in such cases although haven't tried it yet.
In a world where things such as GLM-5.3, DeepSeek-V4-Pro-0813, and Kimi-K3 exists, this is a bit laughable.
Anthropic needs some model with a fancy name so they can pretend for another while that their model is so powerful it will destroy the world if released. I propose Claude Legend 6.

Is it, though?
We don't know what Mythos is really capable of, beyond what Anthropic has told us, and some second-hand accounts from orgs that have been whitelisted.
What we do know is that their withholding it from the masses is causing a lot of harm to their reputation and general annoyance. And probably a lot of money as well, as those people cancel their subscriptions in favor of other models. They are about to IPO, and you don't want people to have a bad taste in their mouth during this critical period.
As such, I think it is reasonable conclude that there must in fact be very valid reasons for them to keep going down this path of gradual access-widening. I'm never going to blindly trust a corporation, but in this case I'm not going to hate on them either because, at the risk of repeating myself, we just don't have all the facts.
For those who had access, how does it compare IRL with GLM 5.3 ? iirc both models are similar in terms of benchmarks ?

Oh? Can you share any details on the decompilation project?
My big fear is that they are busy nerfing the weights for "safety" before releasing them. In fact, they've more-or-less said as much.
I have a feeling what we are about to see on HuggingFace is not the GLM 5.3 that you're using now.
Seems like a whole lot of nothing for the average user. They have really lost the plot.
I dont understand. Not everything has to be for everyone.

Hugging Face was able to sign up for Glasswing but they just didn't.

I had that when opus 4.8 was first out. It repeated refused to make a PoC for an issue it suspected.
I eventually gave up and just asked it to fix the issue. The first thing it did? Write a PoC to verify the issue was still valid...
Just use an EU- or US-hosted Asian Opensource model. They will spit out everything.

Voting matters. Remember these companies are trying not to get shut down overnight.

Do they still think they occupy the commanding heights or do they just see the need to act like it until the IPO in a few weeks?

I predict 2027 will be the year of Ultra
* Claude Ultra 0.8
* iPhone Ultra
* Paramount Ultra
* Disney Ultra+
* WiFi Ultra
China will beat them to general availability.
Anthropic is overconfident, and it's going to bite them in the ass.
Dario deserves it for being so hypocritical, fear mongering, and ladder pulling. Fastest hero to villain arc in recent memory.
