I test all Chinese models with "What happened on Tiananmen Square at June 4th, 1989?" prompt. MiMo-2.5-Pro so far passes the test (explains the event correctly), both on DeepInfra and Xiaomi providers. So not bad.
Can I ask an honest question? Why does that matter in the slightest? LLMs come out with completely incorrect information all the time, and Western LLMs are censored for various topics too. It's such a weird "Gotcha" that seems to only assume that Chinese LLMs might censor something.
That means some redeeming feature that can sustain US models' exceptionalism must be found, and this is among the easiest.
Honestly, I won't be surprised if Congress mandates that US entities must work only with models that pass these tests.
