Osseus

Osseus provides medical and biological datasets, evaluations, and reinforcement learning environments for training frontier AI models. The platform addresses gaps in medical and biological training data, which often draw from narrow populations, conditions, and settings, potentially limiting model accuracy for underrepresented groups. It also focuses on alignment, aiming to help models remain honest, reliable, and responsive to human oversight in unfamiliar situations, particularly in medicine and biology where outputs can influence health and safety decisions.

The platform offers off-the-shelf and custom datasets spanning patient histories, clinical conversations, pathology, molecular data, and experimental results, curated for training and evaluation. Interactive environments present multi-step medical and biological tasks where models gather evidence, analyze data, and use clinical or scientific tools, with feedback on accuracy, uncertainty, and safe behavior. Osseus works with partners on ongoing data collection and uses deployment feedback alongside separately released benchmarks to identify model limitations and evaluate progress.

Osseus is intended for teams working on model training or alignment, particularly frontier labs. The platform is built around partnerships for data collection and deployment feedback. Packaging details such as free plans, trials, editions, or seat-based and usage-based pricing are not specified.
