Leak: Meta's unannounced Wonder Full 1.0 and Spark models spotted in dev tool UI
kevinkern · x · 2026-10-14
A UI screenshot of a "Handoff to new thread" model picker appears to show unreleased Meta (infinity logo) models: Wonder 1.0, Wonder Full 1.0 (selected), Spark 1.3, and Spark 1.2, with reasoning levels Low/Medium/High/X-High/Max and "Wonder Full 1.0 High" active.
This suggests Meta has an undisclosed "Wonder" model line plus Spark smaller models already integrated into a developer tool's model-switching UI. The leak is from a third-party screenshot and unconfirmed by Meta.
