Deepseek v4.1 flash is an open weights model. You can run it on your own hardware. You have no idea how my companies gets access to it. A very cursory Google search would reveal to you that there are many enterprise grade LLM providers that host this model on US soil with SOC2 protections.

Try not to talk about subjects you have no knowledge about because you are making yourself look like an idiot.

Edit: It's also clear to me that you don't deploy any LLM based system on scale because if you had you'd know why open weights models are so compelling.

Hint: it's the cost.
