Meta AI (FAIR) — User Count: 1 billion

NoteThe claim states Meta AI's user count is 1,000,000,000 (1 billion) as of 2025-03 (March 2025). The source confirms Meta AI reached 1 billion monthly active users in Q1 2025 (which includes March 2025). The exact stored value of 1,000,000,000 matches the source's statement of '1 billion monthly active users.' The temporal alignment is precise—both refer to Q1 2025. The source also provides supporting context: 'Meta AI has crossed 1 billion monthly active users as of 2025' and lists the user growth timeline showing 1 billion in May 2025 (Q1). The claim's reference to 'Over 1 billion monthly active users across Meta platforms' is also directly confirmed by the source.
