What Changed This Snapshot?

This snapshot does not redraw the model leaderboard. It changes two specific routes: prompt adaptation and language identification.

Meta Muse Spark 1.3 gained 0.12 points on model-specific prompt adaptation, reaching 8.93 out of 10, and 0.06 points on language identification, reaching 9.86.[^3][^1] Those gains are meaningful enough to reconsider the model for these two tasks—but not for translation, voice-profile generation, Markdown repair, or any other unmeasured workload.

The comparison is deliberately like-for-like. Since 2026-09-05, 829 model-task cells remained comparable, while 4 were added and 199 were dropped.[^2] The movement figures therefore describe continuing measurements, not every model and task currently in the benchmark.

There is also a strong reliability signal: meta/muse-spark-1.3-contributor produced a usable first response without repair or retry on 99.9% of 30,332 attempts.[^2] That supports it where first-pass usability matters. It says nothing about whether the model became faster.

The takeaway: update Meta Muse Spark 1.3’s routing for prompt adaptation and language identification. Leave other routes unchanged unless their own task-level evidence moved.
