Latest update (11-08 09:01): Meta's ABTest Agent computes every reported number with validated code, not the LLM

Overview: Meta reports that its ABTest Agent lets the LLM choose and order analysis steps, while validated tools compute every number it reports. A report template blocks output unless each table traces back to that code. Meta says plain result fetching made up 45% of requests in one study, and 52 of 97 skills checked whether results could be trusted. The source is a Meta paper summarized in a post by Rohan Paul on X.
