Held-out validation
Every model is tested on separate validation data it has never seen. Benchmark performance is the starting line, not the finish.

The Gosta Clinical AI Factory
Europe’s vertically integrated clinical AI infrastructure — from sovereign foundation model training to governed inference inside hospital walls.
We don’t wrap someone else’s model. We train, distill, deploy, and monitor our own — on European supercomputing, under European regulation, with clinicians in the loop at every layer.
We don’t wrap someone else’s model. We train, distill, deploy, and monitor our own — on European supercomputing, under European regulation, with clinicians in the loop at every layer.
Most healthcare AI is built around closed models. Ours is a factory: five layers of proprietary infrastructure, one continuous learning loop. You can certify a closed model. You can’t retrain it, inspect it, or improve it.
Most Healthcare AI
Interface - owned
Closed model - rented
Certifiable — but frozen. What’s inside can’t be opened, and clinician feedback has nowhere to go.
AI management platform - owned
Multilingual foundation models - owned
Task-specific expert models - owned
Clinical model harness - owned
Clinical feedback flywheel - owned
Every layer open to us — inspectable, retrainable, and improved by every clinician who uses it.
Five layers. One learning loop.
Every layer of the Gosta Clinical AI Factory is built, owned, and operated by Gosta — from the governance foundation to the feedback signals flowing back from live clinical use. Intelligence builds up from the foundation. Data flows back from live care. The loop never stops.

Everything above runs on our proprietary AI and data governance platform for healthcare - the system of record for every model, version, approval, and audit trail. Compliance isn’t a checklist we run at the end; it’s the foundation the factory is built on.
Our foundation models are trained and fine-tuned on LUMI, one of the world’s fastest supercomputers - EU-hosted, with complete data sovereignty. Post-training is physician-in-the-loop: our in-house medical experts annotate, rank, and validate as part of the training pipeline itself. Native clinical performance across five languages, not English models with translation bolted on.
We distill our foundation models into compact specialists — each optimized, validated, and versioned for a single clinical task. Right-sized from lean BERT-scale encoders to 27B+ parameter models, they run fast enough for agentic pipelines and lean enough to live inside a hospital.
Frontier capability means nothing if it can’t survive a Tuesday morning clinic. The harness is our orchestration layer: routing each task to the right model at the right latency, composing agentic pipelines, and running inline safety checks - including hallucination detection - before output ever reaches a clinician.
Every clinician interaction is a training signal. Our UI layer streams edit and preference data from real-world clinical conditions into Gosta’s post-training pipelines — preference optimization powered by the people who actually practice medicine, not crowd workers rating text.
Gosta AI Foundation
Train. Deploy. Monitor. Repeat.
The factory is a cycle, not a line. Surveillance findings from live clinical use become retraining data and new success criteria for the next training round on LUMI.
Deploy · choose your jurisdiction
Deploy inside your walls
Deployed entirely inside the hospital’s own environment. Patient data never leaves.
Deploy on sovereign cloud
Hosted on sovereign infrastructure — EU providers under European jurisdiction end to end, or US sovereign infrastructure for American health systems with data-residency requirements.
The Science
A demo is not evidence.
Every model is measured against the clinical success criteria it was commissioned for — before it ever reaches a patient record.
Clinical benefit, not just accuracy
We evaluate technical performance and practical benefit: does essential information survive, do fabricated claims appear, does the clinician actually save time?
Explicit contraindications
For every model, we define where it must not be used. Knowing a model’s limits is part of the model.
Controlled release
Limited pilots with named clinical owners, defined metrics, and a rollback plan - deployment is a change in clinical workflow, not a software release.
Regulation as a design input
Built for the strictest regulatory environment in AI
European healthcare regulation isn’t an obstacle to route around — it’s the specification we build to. Owning the full stack is what makes certification possible.
EU MDR — Class IIa pathway
The sovereign model pathway enables development and certification of clinical AI as a medical device under the Medical Device Regulation.
EU AI Act — ISO/IEC 42001
A full AI Management System governs the lifecycle of every model - high-risk AI obligations engineered into the platform, not bolted on.
GDPR — Data sovereignty
EU-hosted training on LUMI, local inference inside hospital environments. Patient data stays where it belongs.
