Tips
I have currently tested the Gemini API, Qwen, and SiliconFlow, and I recommend using gemini-2.5-flash-lite.
It balances speed and quality, and the price is relatively low. It can also translate sensitive content.
For models above Gemini 3, translating sensitive content may return an empty result, and the price is higher.
