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

I 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.

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?"
