Generalist graders can't evaluate clinical reasoning.
Your model is only as good as your graders. To improve on medical benchmarks, they need domain experts. Most data providers use crowdworkers. Academic partnerships take months. Neither scales.
You need verified physicians. We provide them.
Three steps to better models.
Define the task
Share your rubric or work with us to create one. Pairwise ranking, Likert scales, free-text critique—we support all formats.
We match specialists
Your prompts are routed to physicians with relevant board certifications. Oncology evals go to oncologists.
Get labeled data
Receive structured annotations via API or export. Multi-reviewer consensus available for high-stakes items.
What labs use Cernere for.
Alignment & Preference Data
High-quality physician critiques yielding reasoning traces and preferences for post-training methods like RLHF and DPO.
Red Teaming
Adversarial prompts from practicing clinicians who know where models break. Rare pathologies, drug interactions, ethical edge cases.
Benchmark Creation
Custom evaluation sets with physician-authored questions and gold-standard answers. Build your own HealthBench.
SFT Data
Expert-written clinical reasoning traces for supervised fine-tuning. Chain-of-thought data from physicians, not language models.
