why agent can speak only on English?

[S4ntyC1t]

I am a Russian-speaking student and don't understand English very well. When I asked the agent to speak Russian, they said their system prompt requires them to speak exclusively in English. Could you please remove that requirement from the system prompt?

this problem have on any model with freebuff, but 1 week ago all work okay

Same problem to me. Just use prompts to emphasize the output language, to emphasize it again and to emphasize it again again. Believe me, that does work.

I checked the public mirror for that instruction and it isn't there — no English-only requirement exists anywhere in the agent runtime source, so this comes from the server-side system prompt (which matches your timing: worked a week ago, now enforced). You can't fix it from your side, but you can work around it:

1. Per conversation, instruct explicitly at the start: 'reply in Russian for this whole session'. A direct user instruction normally outranks the default language behavior for that session.
2. If the app supports custom instructions / memory (check settings), put 'Always respond in Russian' there so you don't repeat it.
3. If Russian still gets refused after an explicit instruction, report back with the model name — that distinguishes a prompt rule from a model capability gap.

And maintainers: if this restriction was intentional, it deserves a note in the changelog — silent behavior changes read as bugs, as this thread shows.
