I think their system prompt is in Chinese and probably has instructions to prioritize answering in Chinese, since this has never happened to me via API, where I (or the coding harness) set the system prompt.

I just started learning Chinese instead, like they want us to

seriously

I'm starting to have chinese characters bleed into claude as well. Perhaps a sign of the times. Understanable for a chinese first model but an english first (supposedly) model? wild stuff.

Yes, this is one of the few issues with Deepseek; their chat pages and the app all respond in Chinese. However, i think i have only had it happen once when using the API, and im using it for hours each day for the last... couple of months?

Same issue on desktop. Would be nice be able to set a prefix or postfix for every prompt.

I occassionally get Chinese characters interlaced with English in Google AI Mode, too.

nothing to do with mobile app, I have same issues while using it on desktop browser, it will never remember to use English permanently, even within one conversation
