Sora替代方案

Need AI video generation but Sora is too expensive or unavailable?

OpenAI Sora is the most famous AI video generator but not the only option. Runway Gen-3 costs 35/mo with 9/10 quality. Kling 1.6 has free tier with 8/10 quality. Stable Video Diffusion is free and open source. Real test data from July 2026 shows Kling generates fastest in 20 seconds.
