Mark Zuckerberg, CEO, on earnings call 29 April 2026 Meta (META) Q1 2026 Earnings Call Transcript (Motley Fool)

Factual Their own work or organisation

Meta released its Muse family of models in 2026, starting with Muse Spark, along with a significantly upgraded Meta AI.

Unresolvable The public record could not settle it.

Factual: Statements about the present or the past, checked against the record: did they hold up?

The second judge said resolved true; the verdict shown is the first judge's.

The evidence is the person's or their organisation's own records.

Said for an organisation they lead or work for; it counts on both records.

What would count as true or false

Judge as of 2026-04-29. True: official Meta announcements show that in 2026, on or before 2026-04-29, Meta released a model family called Muse, with Muse Spark as its first model, together with a significantly upgraded new version of Meta AI. Mostly true: all of these happened, but with a minor detail off (for example the Meta AI upgrade rolled out in stages, or Muse Spark was released in late 2025 with the family launched in 2026). Mixed: Muse Spark/the Muse family was released but there was no accompanying Meta AI upgrade, or the reverse. Mostly false: the models were announced but not actually released by 2026-04-29, or were released under different naming in a way the claim misdescribes. False: no Muse models were released by that date.

Set before the research began.

Reasoning

Meta's own announcements show that Muse Spark was introduced as the first model in the Muse series and that the Meta AI app and meta.ai got an upgrade on 2026-04-08 (E1, E2, E3). However, the verdict was lowered to mostly true because the Meta AI upgrade supposedly rolled out in stages, and no evidence item shows that.
