Executive Analysis & Verdict
Muse Ember by Meta is an ultra-fast, budget multimodal agent worker model scoring 44.8 overall, matching Claude Haiku 5.5 on the AA Index v5 (36.0) at one-third of the inference cost ($0.10 / $0.50 per 1M).
Key Strengths & Highlights
- •Unmatched economic efficiency at $0.10 per 1M input tokens and $0.50 per 1M output tokens
- •Matches Claude Haiku 5.5 on the Artificial Analysis Index v5 (36.0) while costing 67% less
- •Expansive 1M context window with 512K output token capacity and 185 tokens/sec throughput
Limitations & Considerations
- •Complex multi-step reasoning requires orchestration alongside larger Muse Wonder models
Architectural Overview & Capability Profile
Muse Ember is Meta AI’s smallest and most cost-effective multimodal foundation model, engineered specifically to serve as a high-speed “worker” sub-agent in production multi-agent architectures. Designed to handle high-frequency, repetitive tasks such as JSON routing, data extraction, test execution, and document parsing without incurring the latency and cost of frontier models, Muse Ember scores an overall 44.8 / 100 on RankLLMs.
Despite its lightweight footprint, Muse Ember features an expansive 1,000,000-token context window with a 512,000-token maximum output limit, natively processing text, high-resolution imagery, audio, and video streams at a rapid 185 tokens per second.
Benchmark Performance & Cost-per-Task Comparison
Evaluations by Meta and independent benchmark testing from Artificial Analysis demonstrate notable value per dollar:
- Artificial Analysis Intelligence Index v5.0:
- Scores 36.0, matching Claude Haiku 5.5 (36.2) and substantially outperforming GPT-6 Luna (28.0).
- Cost-per-Task Efficiency:
- Resolves standardized agentic tasks at approximately $0.136 per task, compared to ~$0.411 for Claude Haiku 5.5—delivering roughly a 67% reduction in operational cost.
- Latency & Execution Speed:
- In benchmark coding quests, Muse Ember achieves a p95 latency of just 2.2 seconds while utilizing 36% to 48% fewer output tokens through compact, direct reasoning.
