MemoryArena - Group Travel Planning Soft Progress Score: leaderboard

Metric: Soft progress score (%) on Group Travel Planning (270 tasks of five to nine sessions): each subtask earns the share of its constraints satisfied, averaged within and then over tasks (task success and hard progress are near zero for every system); the model is the task agent and keeps its full interaction history in context (no external memory); printed as fractions and shown times 100; higher is better. Source: arxiv.org. Saturation forecast: Around January 2027. 5 models tracked.
