Meta released Muse Ember, its smallest model aimed at cheap, repetitive agent tasks. It scores 35.8 on Artificial Analysis' Intelligence Index v5 — nearly matching Claude Haiku 5.5's 36.2 at roughly 1/3 the cost — and cuts per-task cost 17x vs Muse Spark 1.3 ($2.39 → $0.14). Pricing starts at $0.1/M input tokens. It supports 1M-token context, 512K output, native audio/video understanding, and topped CodeArena's WebDev small-model leaderboard. Demo: it audited a $12.6M ledger, finding $2.48M in mismatches. All three Muse models are now on Google Cloud; parameter count undisclosed.
