What the reports cover
Artificial Analysis’s September 2 report evaluates Muse Spark 1.3, including separate effort configurations and a limited preview. Its August 10 Glimmer report examines a smaller open-weight offering. These are dated measurements of different models, not a single score for everything Meta makes.
The everyday takeaway
When a newer model appears, older results remain useful context, but their rankings age. Compare the same task and configuration, and check the actual license before planning a local installation. A hosted assistant and a downloadable checkpoint can have very different requirements.
Our coverage boundary
We have not run these models. Meta’s research page did not expose readable body text during this check, so this briefing relies on the evaluator’s own reports and does not claim a fresh provider announcement. Our separate Muse Wonder briefing covers the October 12 evaluation.
