Overview
What is Gemini Omni Flash?
Gemini Omni Flash is Google's video generation model, built to understand text, images, audio and video together and to make video with its sound in one pass. On Zurelay it makes 720p and 1080p clips of 6 or 8 seconds from a prompt, a start frame, a start and end frame, or up to 3 reference images. The Zurelay Gemini Omni Flash API costs $0.047 per second of video, and a video is charged only once it's delivered.
Google describes Gemini Omni Flash as a high-performance multimodal model for high-speed video generation, editing and cinematic control. It processes text, images, audio and video together, and makes video with audio from a text description. Google released it in the Gemini API as a preview on June 30, 2026. On Zurelay it uses the model ID gemini-omni-flash.
On Zurelay, Gemini Omni Flash makes video from a text prompt, from a start frame, from a start and an end frame it moves between, or from up to 3 reference images of people, products or places you describe in the prompt. Sound is always on: describe the dialogue, effects and music you want in the prompt. Clips run 6 or 8 seconds, at 720p or 1080p, in 16:9 or 9:16.
Video takes time, so the API is asynchronous. POST https://api.zurelay.com/v1/videos returns a job right away; poll GET /v1/videos/{id} until its status is completed, then download the MP4 from /v1/videos/{id}/content or from the signed url in the job. A clip usually takes about 1.5 minutes. Videos are kept for 30 days.
Zurelay prices Gemini Omni Flash by the second, the same at both resolutions: $0.047 per second, so a 6 second clip costs $0.282. Google lists the model at about $0.10 per second at 720p and $0.15 at 1080p. Frames, reference images and the aspect ratio don't change the price. The price is held from your balance when the job is accepted and charged only when the video is delivered; videos that fail, including ones the content filter refuses, are free.
Strengths
Where Gemini Omni Flash shines. And what teams build with it.
Sound in the same pass
Dialogue, effects and ambience come with the picture. Describe the sound you want in the prompt, and time it to the action.
1080p at the 720p price
Zurelay charges the same per second at 720p and 1080p, so the sharper picture costs nothing extra.
Timed direction
Google's guide shows prompts with timecodes such as [0-3s] and [3-6s] to place each beat of the action within the clip.
Use cases
Photos into motion
Start from a product shot, a portrait or a landscape and describe the camera move and the sound.
Before and after
Give a start and an end frame, such as day and night or empty and furnished, and let the clip move between them.
Product placement
Pass a product photo as a reference image and describe the scene to put it in.
Vertical social clips
Make 9:16 clips for stories and shorts, with sound, ready to post.

Wan 3.0 APIHow much does the Gemini Omni Flash API cost?
Zurelay charges $0.047 per second of video at 720p and at 1080p, so a 6 second clip is $0.282. Google lists the model at about $0.10 per second at 720p and $0.15 at 1080p. Frames, reference images and the aspect ratio don't change the price, and a video is charged only once it's delivered.
How do I make a Gemini Omni Flash video from a start frame?
Send POST https://api.zurelay.com/v1/videos with model gemini-omni-flash, a prompt describing the motion and sound, and first_frame set to an image (an https link or a base64 data URL). Add last_frame to end on a second image. Set aspect_ratio to the image's shape, 16:9 or 9:16.
How long can Gemini Omni Flash videos be?
6 or 8 seconds on Zurelay. Leave out seconds and you get 6. Each clip is generated in one pass with its sound.
Which resolutions and shapes does it make?
720p and 1080p, in 16:9 or 9:16. Both resolutions cost the same per second. 360p and 4K aren't available on Zurelay yet.
Can I use reference images with Gemini Omni Flash?
Yes, up to 3 in reference_images, as https links or base64 data URLs. Describe in the prompt who or what from each image appears and what happens. Reference images aren't used as literal frames; to start or end on an image, use first_frame and last_frame instead.
When am I charged for a video?
When Zurelay accepts the job, its price is held from your balance, so videos in progress can never spend more than you have. It's charged only when the video is delivered. If a video fails, including when the content filter refuses the prompt or images, it's free.
Can Gemini Omni Flash edit or extend videos on Zurelay?
Not yet. Google's own API can edit and extend videos in a conversation; on Zurelay, Gemini Omni Flash makes new clips from text and images.
Are the videos watermarked?
Google says every video from the model carries SynthID, an invisible watermark that identifies it as AI-generated. Zurelay is an independent service and is not affiliated with or endorsed by Google.
