DeepSeek-V4.1-Flash-1017 update keeps API pricing and calling method unchanged

DeepSeek-V4.1-Flash-1017 更新

DeepSeek V4.1 Flash has been upgraded to DeepSeek-V4.1-Flash-1017, with the official web and app updated to match. API pricing stays the same and the model is still called through deepseek-flash.

Why it matters: DeepSeek improved the model while holding API price and calling method fixed, and cut task runtime and output length to lower task cost.
