Muse Spark 1.3
Muse Spark 1.3 is a Meta proprietary reasoning model, released 2 Sept 2026. Its best configuration (max reasoning effort) ranks #27 of 785 on the BenchLeader Index at 67.1 ±4.4, in the upper half. The ± is the point: 90 other configurations score within that range, so they and this one cannot be told apart on quality alone — price and speed are what separate them. It scores highest in composite (83) and lowest in maths (63). At $2.00 per million tokens blended it is pricier than most ranked models. Output speed of 116 tokens per second puts it faster than most, with a first answer in 90.1 s. It has been measured at 7 reasoning-effort settings; this summary describes the best-scoring one, and the tabs above switch between them. Last measured 22 Oct 2026.

Versions
Meta has shipped 4 models under this name. Each is ranked on its own results; a newer version often has fewer results so far, which holds its index nearer the average until more arrive.

Reasoning-effort configurations
The same model behaves differently depending on how much it is allowed to think. Each row is one setting, scored only on the benchmarks that were run at that setting. “Not stated” collects results from publishers that did not say which setting they used; for a reasoning model that is usually its thinking mode, but we do not assume it. Pick a setting here or at the top of the page to see its price, speed and category scores.

The index is recomputed from scratch every day, so a line moves when a new benchmark result lands, when a publisher revises a score, or when the models it is normalised against change. Early movement usually means the score is still settling.
