alt Hacker NewsHuggingFace offers DeepSeek as one of its models— it's pretty simple to spin up instances under your control.
I'm not sure about OpenRouter but I wouldn't be surprised if they offer a US-based provider of DeepSeek.
For reference, Cursor has their first own light fork of Kimi that they use as their baseline coding and review model.
The majority of Deepseek providers on OpenRouter for v4 pro are in the US. Especially interesting is that they are in the same ballpark for pricing.
