User-Sim Index

product2 mentions· velocity: stable

The User-Sim Index (USI) is a new metric introduced by researchers for evaluating the performance of LLM-based user simulators across proprietary, open-source, and specialized models.

Two-hop subgraph: this entity, every entity it directly relates to, and every entity those neighbors relate to. Drag a node, scroll to zoom, click to inspect — or click any neighbor and re-center the atlas there.
