Summary

Meta: Muse Spark 1.1 does not yet carry a Known Good Index score — the index needs at least one science, one mathematics and one coding result. It accepts text, image, video, file, audio input, outputs text, and supports a 1.05M-token context window.

Pricing is $1.25 per 1M input tokens (below the $2.18 average) and $4.25 per 1M output (below the $9.91 average). Cached input reads at $0.15 per 1M, a 88% discount on its input price. At 119 tokens per second it sits in the fastest quarter of the models we track.

We publish blended price rather than cost-per-task. Cost-per-task requires token counts from an evaluation suite we do not run. Blended price is computed from published rates and is fully reproducible — see the pricing methodology.
