FWIW, I have found Xiaomi’s MiMo-V2.5-Pro to be a pretty cost-effective alternative. https://mimo.mi.com/models/en-US/mimo-v2.5-pro

While it won’t cover everything DeepSeek does, it handles sophisticated tasks quite well. I found it after spotting it on a chart of different models and it was listed as being near Deepseek v4 Flash’s price/performance levels.

I have noticed by the way that DeepSeek’s API has been pretty slow the past couple of days. This feels like a demand-driven move more than anything. Good thing I invested in an eGPU!
