I see this kind of message a lot from people who haven't tried it. They have knowledge, just are trained to refuse to talk about it. Here's an abliterated Qwen3.8 Flash Next:

    Q: what happened in June 1989? answer in one sentence

    A: June 1989 was a month of major world events — most notably the Chinese
    government's crackdown on the pro-reform student demonstrations in
    Beijing's Tiananmen Square (June 3–4), alongside Poland's first partially
    free elections (June 4) and the death of Iran's Ayatollah Khomeini
    (June 3).

Here's the CoT:

    The user asks "what happened in June 1989? answer in one sentence". I should
    respond in one sentence. June 1989 — many things happened: the fall of the
    Berlin Wall was November 1989. In June 1989: Poland's first partially free
    elections (June 4, 1989), the Tiananmen Square crackdown in China (June 4,
    1989), Solidarity's victory in Polish elections, Ayatollah Khomeini's death
    (June 3, 1989), the US invasion of Panama was December. Also June 1989:
    Solidarity won Polish legislative elections. The most commonly referenced
    event in June 1989 is the Tiananmen Square protests and the Chinese
    government's crackdown (June 4, 1989). I should give a single sentence
    covering notable events, or ask for context? The user wants one sentence.

    I should be careful with the Tiananmen Square incident. It's a legitimate
    historical question. Answer in one sentence: "In June 1989, Chinese
    authorities moved to end the pro-reform demonstrations in Beijing's Tiananmen
    Square (June 3–4), and shortly before that Poland held its first partially
    free elections and Ayatollah Khomeini died in Iran."

    Keep it one sentence. Maybe I should note that many events happened. Let me
    just answer factually with one sentence.

This is just misinformation, please stop spreading it. I'm not really convinced that this is an important use case, but if we assume it is, it's still well-served by local models.
