The full engine, free — nothing held back.

Rather not think about model providers? Let us run your for you — pay-per-use, with full cost guardrails — so no one, not even the model provider, can see your data. It's a no-human-access architecture: the infrastructure itself enforces the privacy, built on confidential computing.
Prefer to run it on a server? We publish guidance and one-command quickstarts for two reference setups — pick the one that fits, and grow into the other later.
Great for one person, or just trying stoa on a server of your own.
For teams and always-on access, with room to grow.
