Hurricane Refinery

Fine-tune models on your own GPU hardware, from the Sentinel console.

Point Refinery at a machine you control, give it a corpus, and it trains a LoRA/QLoRA adapter there inside a pinned container. Your data, your compute, your weights.

• HOWITWORKS.md — the architecture and the decisions behind it
• SECURITY.md — the trust boundary; read this before adding a target
• HELPDESK.md — setup and what to do when something breaks

The short version

A training job outlives the process that starts it, so jobs are durable files that reconcile against the target rather than entries in memory. A corpus is validated and scanned for credentials before it can leave this machine, and the receiver hashes what actually arrived. Weights stay on the target in v1.

Training runs on hardware you supply, and Sentinel's sandbox does not extend to it. That is stated deliberately rather than glossed: see SECURITY.md.
