This is really cool, thanks for sharing this! I tried a few tests and it did pretty well. But it translated 热闹 as "hot and noisy" with this prompt: Give some example sentences using 热闹 with translation.

>这个城市是一个热闹的城市。 (Zhège chéngshì shì yígè rènao de chéngshì.) - This city is a hot and noisy city.

That seems like a very literal translation, never seen that before.
