# What Can't Jev Decide? Probing the Limits of One-Pass Decision Models

Authors: Wang Yang, Xinpeng Li, Yanyan Zhang, Chuang Ma, Shouren Wang, Jianzhe Wei, Liqin Ye, Xiaoran Cai, Mohsen Hariri, Vipin Chaudhary, Xiaotian Han.

Tests models that choose among options in one forward pass without generating reasoning text. Separates retrieval from combining state updates and examines how similar distractor records and stale summaries affect decisions.

## Approaches

- [Analysis and evaluation](https://latent-implicit-thinking.github.io/topics/implicit-reasoning-evaluation/): Measure how well these methods work, investigate what their internal computation does, and identify where they fail. This includes experiments, studies of model internals, and mathematical results.
