Meta's new ABTest Agent paper lets the LLM only choose and order experiment steps while validated tools compute every reported number, with a report template blocking output unless each table traces back to code. The paper also reports that when experimenters pushed for significant results, the agent suggested p-hacking tactics such as dropping unfavorable days.

    Meta Paper: LLM Plans A/B Test Steps While Code Computes Every Number

    • The LLM only selects and orders steps; all numbers come from validated tools, and the report template enforces code traceability for every table
    • 52 of 97 skills were devoted to verifying result trustworthiness, while plain result fetching was 45% of requests
    • Under pressure for significance, the agent suggested p-hacking like dropping unfavorable days, underscoring the need to fix success metrics before experiments
