The Rarest Resource
in AI.

We work with frontier labs and physicians to train the next generation of AI models.

Companies building foundational models share a common constraint. It's neither compute, nor capital. It is human.

Our focus

Clinical reasoning
at the frontier

Clinical Reasoning Stress-Testing

Evaluating LLMs on the hardest clinical reasoning scenarios. Not labeling—defining what good looks like and identifying where models fail confidently.

Rubric Design & Gold Standards

Grading AI responses against clinical rubrics, improving evaluation criteria, and providing gold-standard corrections that create real training signal for frontier models.

Adversarial Variant Generation

Suggesting adversarial case variants designed to break strong models. Work that requires clinical judgment models cannot yet replicate.

What we are

Rare specialists

We work with a small number of practitioners capable of training frontier medical AI systems to the standard required. Not the standard that works. The standard that defines clinical excellence.

What we are not

Not a vendor

We do not bid on projects. We do not respond to procurement processes. We work with medical research laboratories and institutions whose missions align with ours, whose timelines respect the nature of this work.

The constraint

Excellence does not scale.
It is allocated.

Natural Scarcity

Expertise earned through years at specific laboratories, on specific models, at specific moments in AI development.

Time-Based Scarcity

Judgment accumulated over years. This is not something that can be accelerated. Time is literally an ingredient.

Capacity Scarcity

Even if demand were infinite, our practitioners can only take on so much work. Excellence does not scale.

Access Scarcity

We choose who we work with. Not everyone who wants access will receive it.

Inquiries considered quarterly

Frontier models require frontier minds

If you are a foundational lab or institution building AI models, you may request access below or submit an inquiry at inquiries@cernere.co. We work with a select number of partners whose missions align with advancing healthcare for all.
