The Image-to-Video Landscape: Architecture, Models, and Real Prices in 2026
Every serious image-to-video model in 2026 runs latent diffusion on a DiT backbone, so visual quality is no longer a useful axis for choosing one. The real axes are native audio, self-hostability, and dollars per second. Three widely-repeated errors worth correcting: Sora's app shut down on April 26 and its API goes on September 24; Wan 2.7 is described everywhere as Apache 2.0 open weights but no first-party source has them; Veo 3.1 officially costs $0.40/s, not the $0.75/s that circulates on review sites.
