Meta's Muse Spark Models Rapidly Catch Up to Frontier, Rivaling Opus at Low Cost
haider1 · x · 2026-08-09
- Meta's Muse Spark series has evolved surprisingly fast, rapidly closing the gap with frontier models.
- The model progressed from being slightly behind Sonnet 4.6 in v1.0, to matching Sonnet 5 in v1.1, and now reaching roughly Opus 4.8 level with v1.2.
- Pricing is highly disruptive at $1.25/M input and $4.25/M output tokens, though the author speculates the cost is still being subsidized.
