In a side-by-side test, Muse Spark 1.3 Ultra (Meta) and Fable 5.1 ran the same prompt for roughly 2 hours. The prompt required continuous self-improvement until independent judges scored the result above 9.5/10.

Muse Spark never stopped: it completed 20 self-improvement loops, launching 3 agents per loop — 60+ agent runs total — all in Ultra mode for under $1. Scobleizer, who shared the test, says Meta has sprinted ahead of Google here.
