Is DeepSeek Safe? I Tried a US Host

I keep recommending DeepSeek and I keep getting the same reply: sounds great, but I don't want my data going to China. Fair. So I went looking for a US provider serving the same open models and tested Fireworks.

They list DeepSeek V4.1 Flash, GLM 5.3 Flash, and Kimi K3, plus a US-only serverless option. I signed up as a regular user, wired the key into OpenCode, and raced it against OpenCode Go on the same model, prompt, and folder. The US-only endpoints were faster than the regular ones. Not sponsored, I spent my own $10.
