Where sources disagree
Across the 43 benchmarks both have, Gemini 3.5 Flash leads 6, Muse Spark 1.3 leads 37. Every overall index that rates both puts Muse Spark 1.3 ahead.
| Overall index | Gemini 3.5 Flash (high) | Muse Spark 1.3 (max) | Leader |
|---|---|---|---|
| BenchLeader Index | 63.1 | 67.1 | Muse Spark 1.3 |
| AA Intelligence Index v4.3.2 | 32.6 | 48.1 | Muse Spark 1.3 |
| Arena Text | 1477 | 1496 | Muse Spark 1.3 |
Each publisher runs its own tasks, harnesses and effort settings, so their overall verdicts can differ; BenchLeader reconciles them on one scale. † measured at another effort setting of the same model (the publisher did not test the one compared here).
Price, speed and latency
List prices blended at three input tokens per output token. Per-task prices use the token counts on the methodology page; suite cost is what Artificial Analysis paid to run its whole Intelligence Index.
| Measure | Gemini 3.5 Flash (high) | Muse Spark 1.3 (max) |
|---|---|---|
| Blended price per 1M tokens | $3.38 | $2.00 |
| Input / output per 1M | $1.50 / $9.00 | $1.25 / $4.25 |
| Cached input per 1M | $0.150 | $0.150 |
| Price per task: chat reply | $0.0033 | $0.0018 |
| Price per task: summarize a 30-page report | $0.023 | $0.018 |
| Price per task: code edit | $0.022 | $0.014 |
| Price per task: agentic coding session | $0.126 | $0.092 |
| Price per task: structured extraction | $0.0048 | $0.0034 |
| Cost to run a full benchmark suite | $3.69 | $1.60 |
| Output speed | 222 tok/s | 116 tok/s |
| Time to first answer | 14.3 s | 90.1 s |
| Time to a complete answer | 16.6 s | 94.4 s |
Per token is not per task: on Artificial Analysis' full suite Gemini 3.5 Flash (high) cost $3.69 and Muse Spark 1.3 (max) $1.60, because Gemini 3.5 Flash (high) used about 1.4× as many tokens for the same work, which a per-token price hides.
Each model is compared at its best-ranked reasoning-effort setting. Gemini 3.5 Flash (high) scores 63.1 and takes 14 s to its first answer token; Gemini 3.5 Flash (medium) scores 62.8 in 13 s, Gemini 3.5 Flash (minimal) scores 56.4 in 1 s. Muse Spark 1.3 (max) scores 67.1 and takes 90 s to its first answer token; Muse Spark 1.3 (xhigh) scores 64.9 in 30 s, Muse Spark 1.3 scores 59.8 in 3 s. Higher effort means more thinking before the answer: better scores, longer waits and more tokens billed. How reasoning effort changes scores and cost.
