}Gemini Omni 1.2 Flash
Gemini Omni 1.2 Flash, Google’s multimodal video model. Text-to-video, image-to-video from a first frame, first & last frame interpolation, and generation guided by up to 10 reference images. Clips run 3-15 seconds at 24fps.
Audio — every generated video comes with a native audio track (dialogue, music or sound effects, described in the prompt). It is always on: the model has no switch for it, so turning sound / generate_audio off is rejected.
Pricing — per second of generated video, in tokens (USD at $0.02/token). Text-to-video, image-to-video and reference images cost the same; frames and reference images are not charged:
| resolution | tokens/s | USD/s |
|---|---|---|
| 360p | 1.3 | $0.026 |
| 720p | 3.9 | $0.078 |
| 1080p | 5.876 | $0.11752 |
| 4k | 11.752 | $0.23504 |
Example: a 10-second video at 720p costs 39 tokens.
1080p and 4k are upscaled by the model.
Returns an img_uuid; poll GET /api/v1/jobs/detail (or use custom_callback_url) to get the generated video.
Not accepted by this model (rejected before any tokens are charged): turning audio off, negative_prompt (describe what to avoid in prompt), seed, middle keyframes, combining first / last frames with image_urls, and video input (editing or extending a video is not available yet).
