Meta will ship its Watermelon model soon.
Delivered on time The record shows it happened or was so.
Promise: Commitments to the person's or organisation's own future action, with something to deliver: was it delivered?
Said for an organisation they lead or work for; it counts on both records.
What would count as true or false
'Soon' is treated as within about three months of 15 September 2026, that is, by 15 December 2026. The test is whether Meta publicly shipped the model it calls 'Watermelon'. Shipping means a release to users or developers through Meta AI apps, an API or open weights. A release under a different public name counts if credible reporting or Meta itself identifies it as Watermelon. True: Watermelon was publicly released by 15 December 2026. Mostly true: it was released on time but only in a limited public form (for example a limited preview or restricted regions). Mostly false: it was released only after 15 December 2026, or only internally or to a closed partner group. False: dated reports show it was delayed beyond the horizon, cancelled or folded into another project without release.
Set before the research began.

“No source shows Watermelon released or publicly accessible as of Oct 4”
Reasoning
An independent article dated 14 October 2026 reports that Meta released Muse Wonder and Muse Wonder Full on 12 October 2026 (E1). Citing CNBC, it says the project's codename was Watermelon (E2). It also says developers could call Muse Wonder through the Meta Model API as muse-wonder-1.0 (E3), and API release counts as shipping under the criteria. An earlier scan found no release as of 4 October (E4), which fits an October 12 release well before the 15 December horizon.
