Verdict
When to choose each
Muse Ember
Where it leads
- Lower input and output prices, $0.10 and $0.50 vs $1.25 and $4.25 per 1M tokens
- Cheaper cached input, $0.004 vs $0.15 per 1M tokens
Best for
- Sub-agent work under a larger planner such as Muse Spark or Muse Wonder
- High-volume extraction, classification and routing over images, documents and records
Watch out for
- A request over 200K input tokens is billed in full at three times the rate: $0.30 input, $1.50 output and $0.012 cached input per 1M tokens
- Claude Haiku 5.5 scores higher on FrontierCode 2.0 as run by Artificial Analysis (34.9% against 27.2%), a row in Meta's own launch post
- Arena Text has not rated it yet, and its WebDev rating rests on 1,345 votes so far
Muse Spark 1.3
Where it leads
- Higher Arena WebDev score, 1654 Elo vs 1608 Elo
Best for
- Tool-heavy agent loops where fewer calls per task matters as much as the per-token rate
- Coding agents at volume, where its coding scores and low price line up
Watch out for
- Meta’s own documentation states audio understanding is not fully supported and response quality may be degraded on requests containing audio
- The much cheaper contributor endpoint (about $0.10 / $0.20 per million) is priced that way in exchange for Meta training on your traffic. The standard tier is the rate recorded here.
- Meta’s scorecard has it trailing Claude Opus 5 on every broader agent-workflow benchmark it published, including GDPVal-AA v2, despite winning the coding rows
