Facebook is rolling out a new search option called AI Mode that uses Meta AI to generate answers from publicly posted content across Meta apps such as Facebook Groups, Reels, Instagram, and Threads, according to Meta's blog post. The feature appears as an "AI Mode" toggle inside Facebook search and returns synthesized, conversational answers rather than a list of links, as reported by The Verge and TechCrunch. The capability is powered by Muse Spark, referenced on Meta's marketing pages. TechCrunch and AI Chat Daily explicitly raise accuracy and provenance concerns because the model summarizes everyday user posts rather than vetted sources.
