They're the main open source privacy-preserving video models that VeniceAI has started offering with a convenient frontend. Ovi is one with image to video and there is also Wan 2.1 image to video, Wan 2.2 text to video. Wan 2.5 is available but it's routed in an anonymized fashion to the official provider. They're also much more affordable compared to the routed Kling, Veo, and Sora options.
