Overview

About this model

Gemini Omni is Google's first natively multimodal any-to-any foundation model, unveiled at I/O 2026. Unlike pipelines that chain specialized systems, Gemini Omni reasons across text, image, audio, and video in a single forward pass — producing high-fidelity video with synchronized audio directly from a single prompt.

The first model in the family, Gemini Omni Flash, focuses on cinematic video generation with coherent motion, realistic physics, and natively generated dialogue and ambient sound — eliminating the seams typical of multi-stage generative stacks.

1Film & advertising: Generate broadcast-quality video with synchronized dialogue and ambient audio from a single script-style prompt.
2Social content: Produce vertical, square, or widescreen video clips with native sound design for TikTok, Reels, and Shorts.
3Storyboarding: Pre-visualize entire scenes — visuals, dialogue, and sound — before committing to live-action production.
4Localization: Regenerate spoken dialogue in a new language while preserving lip motion and ambient audio.
5Education & explainers: Create illustrative video lessons with narrated voiceover from natural-language briefs.

Implementation Guide

Developer documentation

How to Use Gemini Omni Text to Video

  1. Write a rich multimodal prompt Gemini Omni rewards prompts that describe visuals and audio together. Include subject, action, setting, lighting, camera direction, dialogue, and ambient sound cues. Example: 'A street musician plays a violin on a rainy Paris evening, raindrops tap the cobblestones, a slow melancholic melody, distant café chatter.'

  2. Choose duration Pick 4, 6, 8, or 10 seconds. Longer durations suit narrative scenes; shorter clips work for loops, transitions, and social posts.

  3. Choose resolution

    • 360p — fast, low-cost draft mode
    • 720p / 1080p — standard quality
    • 4K — higher resolution, higher cost

  4. Pick an aspect ratio

    • 16:9 — widescreen, cinematic
    • 9:16 — vertical, mobile-first

  5. Submit and poll POST to /api/v1/gemini-omni-text-to-video and poll GET /api/v1/predictions/{request_id}/result until status is completed.

  6. Prompt tips

    • Describe sound explicitly: 'soft piano underscore', 'wind through trees', 'whispered narration'.
    • For dialogue, wrap the spoken line in quotes and describe the speaker.
    • Specify camera moves — 'slow dolly in', 'handheld tracking shot', 'crane reveal' — for cinematic results.

  7. Example request

    curl -X POST https://api.muapi.ai/api/v1/gemini-omni-text-to-video \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "prompt": "A street musician plays a violin on a rainy Paris evening, raindrops tap the cobblestones.",
    "duration": 8,
    "resolution": "1080p",
    "aspect_ratio": "16:9"
  }'

    Then poll GET /api/v1/predictions/{request_id}/result until status is completed.

Common Questions

Frequently asked

What makes Gemini Omni different from text-to-video models like Veo or Sora?

Gemini Omni is a single foundation model that reasons across text, image, audio, and video in one forward pass — instead of relaying outputs through a chain of specialized models. The result is cleaner edits, native audio generation, and fewer cross-modality artifacts.

Does Gemini Omni generate audio with the video?

Yes — synchronized dialogue, ambient sound, and music are generated natively in the same pass as the visuals. You can disable audio generation if you'd rather add your own soundtrack.

What video durations are supported?

Gemini Omni supports 4, 6, 8, or 10 seconds per generation.

What resolutions are available?

Four tiers: 360p for fast, low-cost drafts, 720p and 1080p for standard output, and 4K for final delivery — each billed per second of output.

When will Gemini Omni be available on muapi?

Google announced Gemini Omni at I/O 2026 on May 19, 2026, with API access rolling out in the following weeks. muapi will enable this endpoint as soon as the API is live — follow the updates page for the launch announcement.
