Muse Wonder has the larger context window (1,048,576 tokens vs 524,288 tokens).

Choose Muse Wonder if…

  • • you work with longer documents, transcripts, or codebases
  • • you need image inputs

Choose Solar Mini 4 if…

  • • lower blended API cost matters for your workload

The benchmark count includes only results measured with a matching benchmark version and protocol. Arena scores are shown separately. Missing, preliminary, and incompatible data is not treated as a controlled win. Published point-score comparisons are labeled separately when protocol details are incomplete. For text-output models, the verdict also compares token pricing and context windows.
