Artificial Analysis Reviews Meta's Muse Ember: Matches Haiku 5.5 at One-Third the Cost
Artificial Analysis published its full evaluation of Meta's latest efficiency-tier model Muse Ember on November 10. The core finding: the model scores 36 on the Intelligence Index, tying with Claude Haiku 5.5 (max), while costing roughly one-third per task ($0.14 vs $0.41), making its value proposition stand out.
Confirmed
- Intelligence Index of 36, on par with Claude Haiku 5.5 (max), at about 1/3 the per-task cost ($0.14 vs $0.41)
- In Artificial Analysis's own coding agent Muse Code, Muse Ember (max) scores 46 on the Coding Agent Index, beating Haiku 5.5 in Claude Code
- Its standout agent result is 68.1% on AutomationBench-AA, on par with the in-house flagship Muse Wonder and GPT-6 Astra
- Agent coding performance is polarized: results vary widely across coding benchmarks
- Cost structure: input/output token pricing matches Claude Haiku 5.5 (max) and GPT-6 Luna (max), but cached input is 60% cheaper and output tokens cost just one-third of Haiku 5.5's; output tokens dominate costs in agent evaluations, which further amplifies the cost advantage
Why it matters
At a fraction of the real-world cost of comparable models, Muse Ember reaches peer-level or even flagship performance on general intelligence and automation agent tasks. If its coding weaknesses are acceptable, it is highly attractive for high-throughput agent workloads. The review also shows its coding ability is inconsistent, so model selection should be weighed against specific benchmarks.
