What does a sovereign AI stack mean?

It means running AI under your own control — self-hosted on your hardware, or on infrastructure in a jurisdiction you choose — so prompts and data never leave your boundary and aren't used to train someone else's model. It trades convenience for control, privacy, and data residency.

Are open models as good as proprietary ones?

For many tasks, yes. Strong open-weight LLMs are competitive with mid-tier proprietary models for summarization, classification, and RAG. The gap is narrower than it was, but the very largest frontier models still lead on the hardest reasoning and coding tasks.

What hardware do I need to self-host an LLM?

A quantized 7-8B model runs on a modern laptop or a single 16GB+ GPU. 70B-class models need a high-VRAM GPU (or several) or an Apple Silicon machine with a lot of unified memory. Smaller models cover most production tasks at far lower cost.

Is self-hosting actually cheaper?

It depends on volume. At low volume, paying per API token is cheaper than running a GPU 24/7. At high, steady volume, self-hosting can cost less per token and gives fixed, predictable spend plus full data control.

Sovereign AI Stack Advisor

Sovereign AI stack advisor

If you can’t send data to a third-party API — for regulatory, privacy, or data-residency reasons — you can usually replace a proprietary AI tool with a self-hostable or open-weight alternative. This advisor maps the tool you use today to viable sovereign options and tells you what running them actually costs in effort and hardware.

How it works

Choose the tool category you want to replace (chat LLM, image generation, speech-to-text, or embeddings) and your hosting constraint (air-gapped on-prem, private cloud, or EU/region-pinned managed). The tool returns matching open or self-hostable projects, each with a one-line description, the deployment effort, and the main trade-off to expect — so you can weigh control against convenience before committing.

Notes and tips

Start with the smallest model that passes your evals: a quantized 7-8B LLM covers a surprising range of production tasks at a fraction of the hardware cost.
“Sovereign” is a spectrum. Fully air-gapped on-prem gives maximum control; region-pinned managed hosting (EU data residency) is far easier and may satisfy your actual requirement.
Budget for the unglamorous parts: model updates, monitoring, scaling, and security patching are now your responsibility, not the vendor’s.
