AWS Bedrock has DeepSeek models running on their infrastructure. That should be enough to prevent training on user data (there's a markup compared to DeepSeek's pricing though).
And unfortunately AWS doesn't have prepaid billing, so you can't just give the internet access to your API key without getting FinDDoS'd.
If anyone is looking for a solution in this space. Fire me an email, I have a partner whose focussed closely on that problem set!
The latest one available for serverless inference looks to be from 8 months (Deepseek v3.1), which is an eternity and far behind.
