A gentle reminder that the only GUARANTEED private AI is with models you are hosting yourself, on your machine or your infrastructure.
Every cloud provider, without exception, will have somewhere in their Terms of Service that they will comply with lawful requests for data from the government of their jurisdiction. For example, this is inference provider Groq:
We may disclose information as necessary or appropriate under applicable laws (including laws outside your country of residence) to: comply with legal process or requirements, including applicable notification obligations; respond in good faith as necessary to requests from public and government authorities (including public and government authorities outside your country of residence)… (etc)
Not only will Groq adhere to lawful requests in its jurisdiction, it may do so outside of it as well.
There are three levels of basic data privacy:
- Completely safe: no one has access to your data – it’s never in a third party’s hands
- Commercially safe: your data will not be used to train on, but humans can still look at it
- Unsafe: your data is being used to train models, and humans can look at it
The good news is that the current generation of open weights models – Nemotron 3 Super, Qwen 3.5, Gemma 4, and many others – are incredibly capable and depending on what kind of infrastructure you have may be sufficient even as a daily workhorse.
Why? Because AI models are engines, and the software you use them in comprises the rest of the car – and you can get a LOT of mileage, metaphorically speaking, from the rest of the car with even a modest engine. For example, Gemma 4 26B-A4B is a lightweight, fast model that is very good at agentic AI. Put inside something like OpenCode or Openwork, told what it has access to, and given robust skills, the engine can handle tasks intelligently and the rest of the app enforces the engine’s outputs.
When you use a model like Gemma 4 on your laptop, it’s completely private. No data gets sent anywhere, which is the best way to work with sensitive data. So when you’re wondering how safe your data is, the golden rule is that the further it is away from you/your machine, the less safe it is.
