Looking at confirmed facts and source claims separately, the boundary is fairly clear. What is confirmed: Facebook launched "Your Algorithm," allowing users to directly add and manage the topics they want to see in their feed and Reels; the feature previously launched on Instagram; Meta also rolled out "Dear Algo" on Threads; users can access it through the three-dot menu, or select "Interested" or "Not interested" on an individual post; these two buttons may also appear below posts.
What belongs to Meta's claims: it may ask follow-up questions; users can express preferences in their own words and recommendations update in real time; after making an update, recommendations "respond right away"; it is using large language models more in its ranking systems; large language models can incorporate the interests, context, and intent behind natural language; recommendations adapt within the same session. None of these have been independently verified.
The report only relays Meta's claims and provides no independent third-party verification of the "real-time update" or "same-session adaptation" effects. This means that, regarding how this feature actually performs, there is currently no cross-checkable evidence in publicly available information.
