One stack, deployed inside your perimeter.
Xvian Core is a multimodal foundation stack — imaging, text, waveform and structured signal in one model family. It ships to your infrastructure rather than pulling your data into ours.
Three layers
Core基盤
Pretrained on de-identified multimodal signal. Frozen, versioned, and hashed — the same weights everywhere, provably.
Adapt適応
Site-specific fine-tuning that runs where the data lives. Gradients leave; records don't.
Attest証明
Every prediction signed and anchored. Explanation surfaces attached at inference time, not reconstructed later.
From contract to first inference
- 01ScopingWe map your modalities, volumes and regulatory surface. Two weeks.
- 02Appliance installAttested hardware racked on your side of the firewall.
- 03Shadow modeModels run alongside existing workflow, predictions logged, nothing acted on.
- 04CalibrationSite fine-tune against your own case mix and reporting conventions.
- 05Go liveClinician-in-the-loop, with override logging on from day one.

What we commit to
| Commitment | Measure | Enforcement |
|---|---|---|
| No data egress | 0 bytes of PHI leave site | Network policy + audit |
| Inference latency | p95 under 50ms | Contractual SLA |
| Model immutability | Weight hash matches anchor | On-chain verification |
| Drift detection | Alert within 24h of shift | Continuous monitoring |
| Audit export | Evidence pack on demand | Automated generation |
Xvian Core is not a diagnostic device on its own. Clinical deployments run under the clearance held for the specific model and indication — see the registry for current status.

Shadow-mode evaluations run for eight weeks with no change to clinical workflow.
