Not only that, DeepSeek "thinks" in English!

When I interact with it by asking it a question in Spanish, the parts between the <think> ... </think> are in English before it goes on to answer in Spanish.

Give it a try in your favourite language.

I went on to ask it if it "thinks" in English, Spanish or Chinese but it just gives the pat answer that, being an LLM, it doesn't think in any language.
