Google Veo 3.1: The Complete AI Video Generation Guide (2026)
Google Veo 3.1 is Google DeepMind's current flagship AI video generation model — the production successor to Veo 3, adding native audio improvements, 4K upscaling, vertical video support, and precise scene-transition control. If you've been searching for "Veo 3" or wondering whether "Veo 4" has quietly launched, here's the short version: Veo 3 has been superseded, Veo 4 has not been released, and Veo 3.1 is what's actually live right now in the Gemini app, Google Vids, Flow, and Vertex AI.
This confusion is common, and for good reason — Google ships Veo updates roughly every five to seven months without always making a lot of noise about version numbers. This guide covers exactly what Veo 3.1 does, what changed since the original Veo 3, why "Veo 4" keeps trending as a search term despite not existing yet, and a complete walkthrough of how to actually use the model — whether you're generating your first clip or building it into a production workflow.
What Is Google Veo 3.1?
Veo is Google DeepMind's dedicated video generation model line — technically distinct from Gemini, though it's most commonly accessed through the Gemini app, which is where a lot of the "Gemini Veo" naming confusion comes from. Gemini is Google's general-purpose AI assistant; Veo is the specialized model underneath it that actually generates the video when you ask for one.
The Veo line started in May 2024 and has moved through several major versions: Veo 1 introduced 1080p video generation, Veo 2 (December 2024) added 4K support and better physics understanding, and Veo 3 (May 2025) introduced native synchronized audio — dialogue, sound effects, and ambient noise generated alongside the visuals rather than added separately. Veo 3.1, released in October 2025, is the version currently in production use across Google's products.
If you're comparing this to how other AI models get positioned, the pattern is similar to what we covered when reviewing Google's Gemini 3.0 Pro — Google iterates its flagship models steadily rather than in dramatic annual leaps, which means the "current" version at any given time is often a point release most casual users haven't heard of yet.
Veo 3 vs Veo 3.1: What Actually Changed
If you last used or read about "Veo 3," here's specifically what's different now:
Veo 3 launches at Google I/O
Introduced native synchronized audio generation for the first time — dialogue, sound effects, and ambient noise generated alongside the video rather than added in post.
Veo 3.1 released
Launched first in paid preview via the Gemini API, alongside a faster "Veo 3.1 Fast" variant. Improved audio quality, video-from-image outputs, and prompt adherence.
Vertical video + reference image upgrades
Added native 9:16 vertical generation for Shorts and social platforms, plus more expressive character movement from reference images even with shorter prompts.
Free tier + Veo 3.1 Lite + upscaling
Google Vids opened free Veo 3.1 generation to all Google account holders. Veo 3.1 Lite launched as a lower-cost API/Vertex AI variant, alongside a standalone 4K upscaling tool.
Veo 3.1 remains the production flagship
Confirmed directly on Google DeepMind's own Veo model page. No Veo 4 has been announced. Google I/O 2026 introduced a separate model, Gemini Omni Flash, instead.
Is Veo 4 Out Yet?
"Veo 4" has been one of the most searched AI terms of 2026 — and almost none of that search volume is being answered honestly. A number of sites have published detailed "Veo 4 features" articles built entirely on release-cadence speculation (Google ships a new Veo roughly every five to seven months, so a next version is plausible) rather than any actual product announcement.
Here's the distinction that matters: a probability is not a confirmation. Google DeepMind's own Veo model page, checked directly for this guide, still leads with Veo 3.1. Prediction markets and industry chatter placed reasonably high odds on a reveal at Google I/O 2026 — and Google did announce a significant new model that week, just not one called Veo 4.
If an article describes Veo 4 features in detail but doesn't link to an official Google DeepMind, Google Cloud, or Google Developers Blog post confirming the model exists, it's speculation — however confidently it's written. Build your workflow around Veo 3.1's real, documented capabilities rather than waiting on rumored ones.
Key Features of Veo 3.1
How to Access Veo 3.1
Veo 3.1 is available through more entry points than most AI video models, spanning free consumer access through to enterprise cloud deployment:
| Access point | Best for | Cost |
|---|---|---|
| Google Vids | Casual creators, quick social clips | Free for all Google accounts |
| Gemini app | General text-to-video from chat | Free tier + Gemini Advanced |
| Flow | Filmmakers, storytellers, structured projects | Included with Google AI plans |
| Gemini API (AI Studio) | Developers building video features | Paid — Veo 3.1 Lite available |
| Vertex AI | Enterprise deployment, EU/GDPR workflows | Paid — Frankfurt region available |
| YouTube Shorts / Create | Direct-to-platform video creation | Free in-app |
For teams evaluating access options seriously, the Vertex AI route matters most for GDPR-conscious workflows — Veo 3.1 is available in the Frankfurt (europe-west3) region specifically for this reason. Worth noting: in the EU and UK, certain features — particularly generating images of real people — carry additional restrictions.
How to Generate a Video with Veo 3.1: Step by Step
Veo 3.1 Pricing
The practical answer for most readers: if you're a casual creator, Veo 3.1 is free. Google Vids opened free Veo 3.1 generation to every Google account holder in an April 2026 update — no subscription required for standard use.
For developers and businesses building on top of the model, pricing runs through the Gemini API or Vertex AI on a per-generation or token basis, with Veo 3.1 Lite available specifically as a lower-cost variant for high-volume or cost-sensitive applications. Enterprise deployment through Vertex AI adds regional options — including the Frankfurt EU region — and integrates with existing Google Cloud billing.
API and Vertex AI pricing for generative models changes frequently and varies by region and volume commitment. Always check current rates at cloud.google.com/vertex-ai before budgeting a production workflow — the figures above reflect free-tier consumer access, which is the most stable part of the offering.
Veo 3.1 Prompting Guide
Video prompting differs from image prompting in one important way: you're describing time, not just a static frame. The prompts that work best specify what happens, how the camera moves, and what the scene sounds like — not just what it looks like.
Name the camera movement explicitly
"Slow push-in," "static wide shot," "handheld tracking shot following the subject" — camera language gives Veo a clear motion instruction rather than leaving it to guess.
Describe the audio, not just the visuals
Since Veo 3.1 generates sound natively, include it: "footsteps on gravel," "distant traffic hum," "she says softly." Leaving audio undescribed produces generic ambient noise.
Keep the action to one clear beat
An 8-second native clip handles one focused action well — a door opening, a hand reaching for a cup — better than a multi-step sequence. Chain clips for longer narratives.
Use frame control for continuity
When building a longer sequence from multiple clips, set the last frame of one generation as the first frame of the next to avoid jarring visual jumps.
What Is Gemini Omni Flash? (And Why It's Not Veo 4)
At Google I/O 2026, Google introduced Gemini Omni Flash — a genuinely new model, but not part of the Veo line and not a "Veo 4" by any official naming. It's worth understanding because it's the actual answer to what Google announced during the exact window many expected a Veo 4 reveal.
Omni Flash unifies text, image, audio, and video into a single consistent output and works conversationally — after generating a scene, you can adjust it without re-prompting from scratch ("make the background a rainy Tokyo street" applied directly to an existing generation). It caps clips at 10 seconds and, like all of Google's generative media output, carries a SynthID watermark identifying it as AI-generated.
The practical distinction for creators: Veo 3.1 remains the tool for longer-form, higher-fidelity, audio-synced video production. Omni Flash is positioned more as a fast, iterative, conversational tool for quick multimodal generation — a different workflow, not a straight upgrade path.
Veo 3.1 vs Sora vs Runway vs Kling
We tested the broader AI video landscape in detail in our guide to the best free AI video generators, which covered Veo alongside seven other tools. Since that comparison was published, Google's model has moved on from Veo 2 to Veo 3.1 — here's how it stacks up against the field today:
| Model | Native audio | Max native length | Standout strength |
|---|---|---|---|
| Veo 3.1 (Google) | Yes — dialogue, SFX, ambient | 8 seconds | Audio sync + first/last frame control |
| Sora (OpenAI) | Limited | Up to 20 seconds | Photorealism, physical simulation |
| Runway Gen-4 | No native audio | Varies by plan | Granular creative control tools |
| Kling AI | Limited | Up to 10 seconds | Realistic human motion, no watermark on free tier |
Native audio generation is Veo 3.1's clearest differentiator — it's the only model in this group where sound design happens automatically as part of the generation rather than as a separate step. If your workflow is audio-independent and you need longer clips, Sora's extended duration may matter more. For a deeper breakdown of what each tool in this space actually does well, our 8 best free AI video generators guide covers pricing, watermark policy, and generation speed across all eight tools we tested.

Frequently Asked Questions
What is Google Veo 3.1?
Google Veo 3.1 is Google DeepMind's current flagship AI video generation model. Released in October 2025 as the successor to Veo 3, it generates video with native synchronized audio, supports both landscape and vertical formats, and offers first and last frame control for precise scene transitions. It's accessible through the Gemini app, Google Vids, Flow, the Gemini API, and Vertex AI.
Is Veo 3.1 different from Veo 3?
Yes. Veo 3.1 improves on the original Veo 3 with better audio quality and sync, native vertical (9:16) video support, first and last frame control, stronger character and background consistency, better prompt adherence for camera and lighting instructions, and 4K upscaling via a standalone Vertex AI tool. Veo 3.1 replaced Veo 3 as Google's production flagship.
Has Google released Veo 4?
No. As of mid-2026, Google has not officially announced or released a model called Veo 4. Veo 3.1 remains the current production flagship, confirmed directly on Google DeepMind's own model page. Google I/O 2026 introduced a related but separate model, Gemini Omni Flash, which is not part of the Veo line.
Is Google Veo 3.1 free to use?
Yes, with limits. Google Vids offers free Veo 3.1 video generation to all Google account holders as of an April 2026 update. Higher-volume or developer access through the Gemini API and Vertex AI is paid, and a lower-cost variant called Veo 3.1 Lite is available specifically for cost-sensitive API and Vertex AI use.
How long can Veo 3.1 videos be?
Veo 3.1 generates native clips up to 8 seconds in length, as documented on Google DeepMind's own Veo page. Longer sequences are typically built by generating multiple clips and using first and last frame control to stitch them into smooth, continuous scenes.
Can Veo 3.1 generate audio?
Yes. Native audio generation was introduced with Veo 3 and improved in Veo 3.1. The model generates dialogue, sound effects, and ambient noise synchronized to the video, removing the need to source or generate audio separately for most short-form clips.
What is Gemini Omni Flash and is it the same as Veo 4?
Gemini Omni Flash is a separate multimodal model Google introduced at Google I/O 2026, not a Veo successor. It unifies text, image, audio, and video into one output and works conversationally — you can adjust a scene without re-prompting from scratch. It caps clips at 10 seconds and always carries a SynthID watermark. Despite speculation, Google has not positioned it as "Veo 4."
How does Veo 3.1 compare to Sora and Runway?
Veo 3.1 sits in the same professional-quality tier as OpenAI's Sora and Runway's Gen-4 models. Its main differentiator is native synchronized audio generation, which neither Sora nor Runway matches as reliably. Runway offers more granular creative control tools; Sora supports longer native clip lengths. The right choice depends on whether audio generation or fine creative control matters more for your workflow.
Summary: Build on What's Actually Live
Veo 3.1 is a genuinely strong video generation model, and the fact that so much online content is chasing an unreleased "Veo 4" instead of covering what Veo 3.1 actually does well is a real gap worth closing. Native audio, first/last frame control, and free access via Google Vids make it one of the more practically useful AI video tools available right now — not despite being "only" 3.1, but because 3.1 is a substantial, shipped, documented upgrade over the original Veo 3.
If your workflow spans multiple AI tools rather than just video, it's worth reading alongside our broader looks at AI content creation tools and common AI myths — both cover the same pattern seen here: the gap between what a tool is marketed as and what it actually, verifiably does.
Open Google Vids, upload one product photo or reference image you already have, and generate a single 8-second clip with a specific camera movement and one audio cue in the prompt. That one generation will tell you more about Veo 3.1's real capability than any spec sheet — including this one.
