Muse Spark 1.3 evaluated on the hub's only benchmark

Released on 2 September 2026, Muse Spark 1.3 (Meta) joins the hub's rankings: its place on the Business Index, its strongest and weakest business functions, its cost and its hallucination rate.

Report written by the hub from the published rankings: every sentence is computed, none is an opinion.

  • 5th of 27 on the Business Index, at 100.0% (95% margin of error: ± 0.0 points).
  • 1.7 index points above Llama 4 Maverick, its predecessor at Meta, released on 5 April 2025. The gap is smaller than the margin of error: the two models cannot be told apart.
  • Mean cost per test: $0.013, the 18th cheapest of the 27 models with a known price.
  • Mean hallucination rate: 0.0%, the share of items missing from the source for which it invented a value.
  • It took the hub's only published benchmark.
