High Quality Data
Orinn is trained on high-quality medical data sourced from textbooks, research papers, and partner medical institutions. We don’t rely solely on web scraping.
Specialized Algorithm
No single algorithm is sufficient for every domain, so we designed a highly personalized one specifically for healthcare.
RL with Professionals
We trained and applied RL with a team of doctors, so the model learns to align closely with real medical expertise.
Affordable Intelligence
Our new model, Orinn 1.5, is far more affordable than others—hosting 8B model while delivering the same level of efficiency.
HealthBench
We evaluated Orinn 1.6 on OpenAI’s HealthBench benchmark to measure medical reasoning, reliability, and hallucination safety compared with leading frontier models.
Orinn 1.6 achieves the highest score across the benchmark, demonstrating stronger reliability and lower hallucination rates.
