| Error messages matching Z.ai GLM I think are the simplest/most compelling. I had Opus 4.8 poke it and it came back with a couple different errors than the article mentions. Matching the tokenizer is interesting tho |

| ▲ | randomblock1 an hour ago | parent [-] | | I find the tokenizers most compelling. That's what the model is trained on, it's an immutable fact of the model and its architecture. You know for a fact that the model is at least related to other models that way. And if a tokenizer is unique / specific to one lab, like GLM's is, it's basically as good as it gets. Comparatively, you can't be 100% sure that Z.ai isn't able to host some other lab's model (although in this case, the hosting errors still support the GLM theory). | | |
| ▲ | Chu4eeno 14 minutes ago | parent [-] | | No, that's not how anything works. You can finetune an LLM to a new tokenizer by nudging just a few layers (even wildly different kinds of tokens), and there's nothing stopping a lab from using someone else's tokenizer. |

| Another strong hint is that the uptime graph of GLM-5.3 by Z.ai is very similar to that of Ox Alpha: https://openrouter.ai/stealth/ox-alpha#uptime https://openrouter.ai/z-ai/glm-5.3#uptime Screenshot of a recent blip: https://files.catbox.moe/haq90y.png |

| Can someone explain why people care about that? Both as in "Why is there a stealth launch like that in the first place?" but also "Why does it matter? Is it very good in something?" |
| |
| ▲ | Philpax 3 hours ago | parent | next [-] | | Stealth launch: builds hype, allows them to collect user preference data and see where the model fails.
Why people care: it's free, decent, and people love a good mystery. | | |
| ▲ | hypfer 3 hours ago | parent [-] | | Aaah, free inference. Yeah that checks out and fits very well with weird Internet hype. Okay, fair enough. Thanks! | | |

| ▲ | chermi 2 hours ago | parent | prev | next [-] | | I think there was some loud speculation is was Google. It's cool people can pretty definitively show it's not. But also maybe Google is being crazy sneaky and faking it! (Joking) | |
| ▲ | tcdent 3 hours ago | parent | prev | next [-] | | I think the stranger thing is that people spend tens of hours doing analysis like this to hit an inevitably-expiring hype cycle that will give us a definitive answer shortly. | | |
| ▲ | chermi 2 hours ago | parent | next [-] | | Don't you think the forensics is fun?! This is exactly the sort of thing i would've expected hn to be broadly interesting to hn. It's a complicated technology and people are poking it and learning things | |
| ▲ | cgorlla 3 hours ago | parent | prev [-] | | It's fun! Also it's an interesting commentary on where the AI industry is as a whole. |
| |
| ▲ | cgorlla 2 hours ago | parent | prev [-] | | It's decent. How good depends on compute needs. |

| Speculation that this is GLM 5.3 Flash. |
