Meta’s Muse Revival, Frontier AI Under Threat, The Rise Of Dopamine Sites

Meta's Muse shows a non-frontier model plus strong product 'harness' can beat frontier labs and disrupt commerce aggregators.

• Muse tops the App Store: Meta's consumer AI agent hit #1 two weeks post-launch but usage is modest — 500K+ tryouts, ~250K-800K daily actives, 2M prompts (~4/user); Meta stock rose ~20% since Aug 25, its best day since April 2025.
• Harness beats frontier model: Hosts argue Meta built Muse on a non-frontier model, proving that connectors, memory, and product design ('the harness') matter more than raw model intelligence — a Ramp Economics Lab chart shows frontier models fell from 53% to 45% of AI spend (Aug 2-Sept 6).
