HAL Reliability - Overall: leaderboard

Princeton HAL Reliability Dashboard aggregate for agents built from one LLM inside HAL's harness, run three or four times per task on GAIA and a cleaned 26-task tau-bench airline subset. Overall reliability is the mean of the consistency, predictability and robustness indices, with safety reported separately; 0-1, higher is better.

Metric: Overall reliability (0-1, mean of consistency, predictability and robustness; higher is better). Source: hal.cs.princeton.edu. Saturation forecast: Around February 2027. 15 models tracked.
