Side-by-side comparison of pricing, 12 benchmarks, and generation speed.
| Metric | Muse Spark 1.1 (xhigh) | o3-mini |
|---|---|---|
| Input ($/M tokens) | $1.25 | $1.1 |
| Output ($/M tokens) | $4.25 | $4.4 |
Verdict. Muse Spark 1.1 (xhigh) wins the overall benchmark matchup 2–0 across 2 overlapping categories, but raw benchmark score is only one input to the decision.
Pricing. Both models sit in the mid-tier bracket for output-token pricing. At 1.0× the per-million-token cost, Muse Spark 1.1 (xhigh) is meaningfully cheaper if your traffic is output-heavy (long completions, document generation, agent loops). Muse Spark 1.1 (xhigh) makes more sense when output volume is low and absolute reasoning quality justifies the premium.
Strengths. Muse Spark 1.1 (xhigh) is strongest on Coding Index (71.3), Intelligence Index (53.2). o3-mini leads on Intelligence Index (19.2).
Speed. Throughput is comparable — 179 tok/s vs 203 tok/s — so generation speed shouldn't drive your choice here. Look at the per-benchmark wins instead.
Provider. Meta and OpenAI sell to overlapping but distinct developer audiences: Meta tends to ship frontier reasoning models with premium positioning, while OpenAI often prices more aggressively. Your existing vendor relationships, billing, and SLA preferences may matter as much as the raw numbers above.
Workload cost. Workload scenarios (per million requests at 30M input + 15M output tokens): Muse Spark 1.1 (xhigh) costs $101.25 ($1215/year); o3-mini costs $99.00 ($1188/year). At a smaller 5M-input/2M-output scale (single-developer tool or prototype): Muse Spark 1.1 (xhigh) ≈ $14.75/run, o3-mini ≈ $14.30/run. At agent/realtime scale (200M input / 100M output per million requests): Muse Spark 1.1 (xhigh) ≈ $675/run, o3-mini ≈ $660/run. o3-mini becomes more attractive at higher volume — the absolute per-token pricing difference compounds when you ship at scale.
Recommendation. Both models have legitimate use cases — the right answer depends on whether you are optimizing for benchmark ceiling, latency, or unit cost. Start with the cheaper / faster model, evaluate against your specific task, and only switch if the upgrade shows a meaningful lift.
