Pick Microsoft MAI-Image-2 if...

  • Higher output quality (8.5 vs 7)
  • Easier to use (6.5 vs 5)

Microsoft shops already on Azure or M365 Copilot who need a first-party image model without an OpenAI dependency. Also good for any high-volume programmatic image workflow (ad creative, product photography variations) where MAI-Image-2-Efficient's 4x cost efficiency materially changes the economics.
