Cura 1T introduces a novel training methodology for healthcare LLMs using a human-gated self-evolution loop that specifically targets the degradation issues common in narrow updates. By refining its data mixture based on observed failures, this model achieves top-tier performance across diverse agentic tasks like clinical reasoning and EHR tool use without sacrificing out-of-domain capabilities. The approach offers significant insights for developing robust vertical-specific models where task interdependence is critical.
Cura 1T: Specialized Model for Agentic Healthcare
arXiv:2607.15314v1 Announce Type: new Abstract: Healthcare spans high-stakes communication, expert reasoning, and workflow execution, yet specialized LLMs that cover these use cases together remain limited. A healthcare model must handle patient consultation, clinical reasoning over text and images, interactive diagnosis, and electronic health record (EHR) tool use. These capabilities fail in different ways, and a narrow update for one task can degrade another. We present Cura 1T, a healthcare-specialized LLM trained through a human-gated self-evolution loop. In each evolution round, a training agent plans a target capability, trains the model, evaluates benchmark trajectories, and refines the data mixture from observed failures. This data-centered loop improves the model through targeted synthetic and curated examples rather than a single generic medical-data update. Across the healthcare evaluation suite, Cura 1T ranks at or near the top among frontier baselines, while remaining competitive on out-of-domain reasoning and agentic benchmarks.
