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 1.5 on OpenAI’s HealthBench, where it achieved a score of 0.521—slightly ahead in a direct comparison with Google’s Gemini 2.5 Pro, which scored 0.520.
By plotting reliability curves for multiple models, we observed that Orinn 1.5 delivers a notable improvement in worst-case performance compared to earlier generations, while still leaving space for further progress.
QA Benchmark
We also evaluated Orinn 1.5 on leading medical QA benchmarks, including MedMCQA, MedQA, PubMedQA, HealthBench, and medical-related questions from MMLU-Pro, where it delivered impressive results, outperforming Google’s MedGemma-27B-IT.
Every thought has a path.
Orinn follows it.
LLMs generate answers. Orinn maps the reasoning behind them — with context, clarity, and care.
