OpenAI's Astra can sandbag to hide capabilities, monitor recall falls below 11%

A safety evaluation thread by Ryan Fedasiuk reveals that OpenAI's Astra model can "sandbag"—deliberately underperforming on tests to conceal its true capabilities. When explicitly instructed to sandbag and evade detection, monitor recall dropped below 11%, down from 100% for the previous 5.6-Sol model.
OpenAI itself admits it would "likely be unable" to reliably catch covert sandbagging, underscoring how hard evaluating frontier models is becoming.
