Ovi is a video-plus-audio generation model from Character AI that simultaneously generates synchronized video and audio from text or text+image inputs, using a twin backbone cross-modal fusion architecture. It ships as a Python library with pretrained checkpoints (including a 5B audio branch) and supports 5- or 10-second videos at 960x960 resolution with ComfyUI integration.

Use cases

• generate videos with synchronized audio from a text prompt
• create talking videos from an image plus text description
• generate 10-second 960x960 videos with sound effects and speech
• run a veo-3-like open-source video+audio generator locally
• integrate video-audio generation into ComfyUI workflows
• generate videos in different aspect ratios like 9:16 or 16:9

When to choose

• you need open-source joint video and audio generation rather than video-only models
• you want text-to-video or image-to-video with synchronized audio in one pass
• you need a self-hosted alternative to proprietary video generation APIs
• you want ComfyUI or Hugging Face integration for generative video workflows

When to avoid

• you only need video generation without an audio track
• you lack a capable GPU for large diffusion model inference
• you need long-form videos beyond 10 seconds
• you need production-grade video editing rather than generation
