What Is Google Gemini Omni? Text/Image/Audio → Video AI (Features + Who Can Use It 2026)

Quick answer: Gemini Omni is Google's new model unveiled at Google I/O 2026 (May 19) — combining Gemini's reasoning with content creation, especially video. It accepts text + image + audio + video input, generates video output, and crucially lets you refine results conversationally (change the scene, shift the style, trim a beat). The released variant is Gemini Omni Flash, available immediately to Google AI Plus / Pro / Ultra subscribers via the Gemini app, Google Flow, and YouTube Shorts Remix. Omni Pro was mentioned but not yet released.

What Gemini Omni Actually Is (no hype)

Omni = omnimodal — receive and generate multiple modalities from one model. Previously, Google had Veo (video), Imagen (image), and Gemini (chat/reasoning) as separate stacks. Omni fuses them into one model — drop in a photo with a voice command and caption, and Omni understands all of it together, then produces a video. Outputs are described as "grounded in real-world knowledge" because Gemini's reasoning runs underneath — not a bare generative model.

What It Does — 4 Core Capabilities

From what Google demoed at I/O 2026:

• •1. Text → Video — type a prompt, get a short clip out (exact length/quality specs not detailed yet).
• •2. Image → Animation — drop in a still photo, Omni adds motion. A dog runs, a person walks, a logo animates.
• •3. Conversational editing — talk to the AI to refine the scene: "brighten it," "make it more cinematic," "trim the first two seconds" — without opening a video editor.
• •4. Multimodal real-time response — feed text + audio + image together and Omni responds and generates in real time.

Who Gets It First — Pricing + Tiers

Omni Flash is rolling out globally from I/O day for these subscribers:

Omni vs Sora / Veo / Runway

The AI video market is crowded — where Omni sits:

• •vs Sora 2 (OpenAI) — Sora's consumer app shutters April 26, 2026. Omni walks into that gap, with Google's distribution edge (YouTube Shorts, Workspace).
• •vs Veo 3.1 — Veo is Google's pure video model. Omni is a superset with Gemini reasoning fused in, enabling chat-based editing Veo doesn't do.
• •vs Runway Gen-4 / Pika 2.0 — Runway/Pika lead on creator workflow + serious production pipelines. Omni wins on integration (type in Gemini app → use in Flow → post to YouTube Shorts).
• •vs Kling 3.0 — Kling leads on physics + human motion. Omni hasn't published comparable physics benchmarks yet.

What Thai Creators and Businesses Can Actually Do With It

Omni fits these Thai-specific jobs well:

• •Shopee/Lazada sellers — turn a product photo + Thai caption into an ad clip for Facebook/TikTok in minutes (vs ฿2,000-5,000 per clip from a freelance editor).
• •Thai YouTube Shorts creators — use Shorts Remix to spin variations of existing clips for daily uploads without re-shooting.
• •Marketing agencies — produce mood reels / concept videos for client pitches in 1-2 hours instead of 1-2 days.
• •Teachers / online course creators — animate existing slide images into explainer videos that learners actually retain.
• •Restaurants / cafés — animate signature-dish photos for LINE OA / Facebook posts without hiring a pro camera crew.

Limits + What's Still Unclear (May 2026)

As of the day after launch, many specifics are pending:

• •Clip length/quality — Google hasn't published max duration or resolution. Likely close to Veo (10-30 seconds).
• •Watermarks — Google embeds invisible SynthID watermarks in all AI video. Omni almost certainly does the same.
• •Commercial usage rights — terms vary by plan; re-read Google's Terms before running real Facebook Ads.
• •Thai prompts — Omni understands Thai prompts (Gemini is strong multilingual), but Thai text rendered on the video still comes out wrong (true for every AI video model). Add subtitles via CapCut afterward.
• •Omni Pro — no release date, pricing, or capabilities announced yet.
