AI2 Releases StateBench to Evaluate Long-Context State Tracking
- StateBench focuses on evaluating accuracy in tracking evolving information (e.g., variable assignments, plot developments) within long texts.
- It provides fine-grained analysis to help researchers identify specific points where models lose or confuse state information.
- Aims to serve as a 'North Star' metric and data source for developing new architectures with robust state-tracking capabilities.
