So I stumbled on something interesting while exploring Z.ai.

I noticed that the Z.ai logo actually points to chatglm.cn. Out of curiosity, I followed the link… and ended up on what looks like the same service, but in a Chinese version.

A few differences stood out immediately:

• It supports login via WeChat
• The interface is clearly tailored for the Chinese market

But here’s the part that really caught my attention:

• On chatglm.cn, you can upload files up to 100 MB
• On Z.ai, the limit is only 50 MB

Same product (or at least very similar), but different limits depending on the region.

Now I’m wondering:
Is this a technical limitation?
A business decision?
Or just different deployment configurations?

Curious if anyone else has noticed this kind of behavior with other AI tools !
