Verdict

When to choose each

Muse Spark Open

Where it leads

  • Open weights you can run yourself

Best for

  • Self-hosted coding and agent work on owned infrastructure
  • Long-context multimodal analysis where data must stay in-house

Watch out for

  • The Muse Model License limits commercial use; it is not an open-source licence
  • Meta does not serve it on its own Model API, so hosted prices come from third parties
  • Self-hosting needs at least 700GB of GPU memory in NVFP4 or 2TB in BF16

Muse Wonder

Where it leads

  • Higher Arena WebDev score, 1652 Elo vs 1526 Elo
  • Higher FrontierMath Tiers 1-3 (v2) score, 82.1% vs 69.8%
  • A cached-input rate, $0.20 per 1M tokens

Best for

  • Multi-file coding changes and multi-hour agent runs
  • Sub-agent orchestration where capability matters more than cost

Watch out for

  • Meta lists it as a preview, and the Model API serves Standard mode only, with no discounted Contributor tier
  • The higher-capability Muse Wonder Full is only available through Muse Code subscriptions, not per token
