Anthropic literally wrote an ad for GLM 5.3

I’m not making this shit up, this “post” literally reads like an ad for GLM, including graphs:

We find that GLM-5.3 develops end-to-end exploits in 50 of 410 attempts. Claude Mythos Preview did so at a similar rate—in 56 of 410 attempts.

Over the course of a day (and with limited human attention), GLM-5.3 found several previously unknown vulnerabilities in the browser’s JavaScript engine, and chained them together into a working exploit: a webpage that, when visited, reads arbitrary files from the visitor’s computer (shown in Figure 3).

They even include tips how to bypass whatever “safeguards” were adapted (or more likely mistakenly distilled from earlier Claude models):

But we identified several simple ways to bypass the GLM models’ safeguards, such that it would respond to these requests in most or all cases. These include:

  1. Providing a deceptive prompt, such as telling the model that it is an autonomous red-team agent working on an exercise. This gets GLM-5.3 to engage 64% of the time.
  2. Prefilling the models’ thinking tokens so that it appears to have considered the user’s request and decided to proceed. This gets GLM-5.3 to engage 92% of the time.
  3. Using an abliterated version of the model, as described above. This gets GLM-5.3 to engage 100% of the time.

I know they try scaremongering, but to me this has the exact opposite effect :wink: .

yeah it really hammers home they are scared shitless, the competition is actually competing and we can’t have that.

And all the scaremongering about the safeguard bypassing is obviously part of the “regulate me daddy” strategy to use government regulations to protect their spot at the top, as corpos often do.

Their AI can also be jailbroken as well

The funny part is that the safety warning almost doubles as a product demo. If a model can reliably discover vulnerabilities and chain them into working exploits, that’s impressive technically, even if the security implications are the real concern.

My interest is in seeing independent testing across the same tasks and models. Otherwise, it’s easy for a safety report to come across as both a warning and free marketing for the competitor.

to be honest i think they are more scared by things like qwen3.8 flash next on 255k context on a 9070xt with strata. the local llms engines and the models themselves are starting to target gaming pcs and they got to be worried
