- nijave 3mo agoError 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 3mo agoI 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 3mo agoNo, 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.
- johndough 3mo agoAnother 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/stealth/ox-alpha#uptime https://openrouter.ai/z-ai/glm-5.3#uptime https://openrouter.ai/z-ai/glm-5.3#uptime Screenshot of a recent blip: https://files.catbox.moe/haq90y.png https://files.catbox.moe/haq90y.png
- hypfer 3mo agoCan 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 3mo agoStealth 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 3mo agoAaah, free inference. Yeah that checks out and fits very well with weird Internet hype. Okay, fair enough. Thanks!
- handfuloflight 3mo agoIt's a good model ser.
- tcdent 3mo agoI 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.
- cgorlla 3mo agoIt's fun! Also it's an interesting commentary on where the AI industry is as a whole.
- chermi 3mo agoDon'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

- UncleOxidant 3mo agoSpeculation that this is GLM 5.3 Flash.
- cgorlla 3mo agoVery likely, NYT confirmed it's releasing Friday.

- Frannky 3mo agoI was using it side by side with GLM 5.3, and they were very, very similar. Also, the new zhipu 1 GW data center plus a flash(smaller?) model, can justify the 100T/day they said they were able to serve. Pretty cool model, especially since it's not a nanny, if you want to unlock your own devices, like rooting an Android, it will happily help instead of flagging you. Available for free via OpenRouter and Nous free tier. Also via OpenCode Go, but you have to pay a $5–$10 subscription. APIs are hammered now, so service is bumpy.
