Choose GPT-6.1 Sol if…

  • • you need a model with explicit reasoning support

Choose Hy Image 3.5 Preview if…

  • • you need image generation

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.
