It provides up to 15-second video generation with native audio, multi-input reasoning (supporting text, image, and video inputs), character consistency across up to 6 reference images, and multi-turn conversational editing and extension. The Veo 3.1 Preview in the Gemini API has been shut down. ## Gemini Omni Flash {% id="omni-flash" %} Gemini Omni Flash (`gemini-omni-1.2-flash`) is a fast, multimodal model for video generation and conversational video editing. It excels at turning text prompts and reference images into 3 to 15 second videos with native audio, and lets you refine or extend results across multiple turns using the Interactions API.
