Ehsan's Verdict

The Runway vs Stable Diffusion debate misses a critical nuance. Runway was built for video-first teams and it shows in the API design and workflow assumptions. Stable Diffusion approaches image from first principles with a cleaner mental model. For 2026, pick Runway if you have existing infrastructure, Stable Diffusion if building greenfield.
