OpenTumorBoard - Board Simulation: leaderboard
The model simulates a whole tumor-board discussion for a real case and reaches a consensus on therapy, surgery, next steps and trial matching. An LLM judge scores alignment with the real board's conclusion on a 1-5 scale, higher is better (OpenTumorBoard, 2026).
Metric: Conclusion alignment (1-5) of a simulated multidisciplinary discussion's consensus with the real tumor board's conclusion, mean over 184 test cases (malformed outputs score 1; judged by Qwen3.8-27B); higher is better. Source: arxiv.org. Saturation forecast: Around 2033. 14 models tracked.
