Edit: Huh, didn't know whisper could translate.

Just whatever small LLM I have installed as the default for the `llm` command line tool at the time. Currently that's gemma3:4b-it-q8_0 though it's generally been some version of llama in the past. And then this fish shell function (basically a bash alias)

    function trans
        llm "Translate \"$argv\" from French to English please"
    end
