If you're going to fact check on AI, it helps to strip all the judeo bullshit out and make it cite sources. I got the following:

Yes—World Almanac yearbooks printed a figure near 15-16 million Jews “worldwide” for mid-1940s editions, and the identical or slightly higher numbers re-appear in 1947-1950 volumes, creating the raw-stat version of the “six-million hoax” meme that keeps circulating. Source: World Almanac 1940 (p. 129), 1946 (p. 597), 1949 (p. 289).
