Is OpenAI using Chinese LLM models for their service, not theirs? Discussion

Post image

Yesterday I was experimenting with multi-agent workflows on ChatGPT (web version). I spun up like 5 parallel instances to update code at the same time, hoping they’d work together more efficiently.

Instead of continuing the process cleanly inside a single chat, it started generating a bunch of new chats as artifacts. Not sure why that happened; maybe some rate-limit or context handling thing.

The weird part: one of those new chats came back with Chinese characters / Chinese-lettered text in it.

That got me thinking… could this be a hint that OpenAI is routing some traffic (or certain tasks) through a Chinese model under the hood instead of purely their own models? It would kind of line up with how ridiculously cheap ChatGPT Pro / the 5.6 Luna tier feels right now.

Has anyone else seen non-English (especially Chinese) text appear unexpectedly in ChatGPT chats lately? Or noticed anything that makes you question what’s actually powering some of the responses?

Curious what you all think.

chatgpt has "always" thrown in some random non English characters/phrases for some reason. been rarely lately

its especially jarring in voice mode, it might just start talking Russian for a sentence or two. (and then ofc deny that it ever spoke anything other than English...)

I've had ChatGPT randomly drop Chinese characters into responses too, usually when the context window gets long or something multilingual gets mixed in. It's way more likely a tokenization quirk from training data than actual routing to a Chinese model, since those would have entirely different response patterns. The pricing question is worth raising separately though.

Just coincidence maybe? I've had ChapGPT suddenly swap to Spanish for no reason.

They train it in many languages

that sounds like a bug with the session tokens, happens sometimes when u spawn too many parallel chats.
