# The Best AI Video Generation Models in October 2026: What Changed and Which to Use

Six months ago the answer to "which AI video model should I use" had Sora in it. As of October 2026 it does not: OpenAI closed the Sora app in April and switched off the API on 24 September. In the same stretch Google folded Veo into a new multimodal model, ByteDance shipped a Seedance that makes 30-second clips, and an Alibaba model nobody outside China had used in July took the top of the public leaderboard.

Most "best models" lists were written before any of that. This one is dated on purpose. It covers the models that matter this month, what each is actually for, what they cost per second, and how to pick one without reading another ranking next week. We generated clips with two of them ourselves this month, and we say which claims are ours and which are someone else's.

**Key takeaways**

- There is no single best model. Seedance 2.5 and Wan 3.0 lead the text-to-video leaderboard; Veo 3.1 still wins for cinematic realism and audio; Kling 3.0 is the storyteller; Gemini Omni Flash is the cheap, fast default for most work.
- Sora is discontinued. If a tool you use still lists it, the listing is stale.
- Price per second ranges roughly tenfold between models, and most charge several times more at 1080p than at 480p. Draft cheap, render once.
- Open weights are real now: MiniMax H3, Wan 2.2, LTX-2.5 and HunyuanVideo 1.5 can be self-hosted.
- The leaderboard was reset this summer, so Elo numbers from before August are not comparable with today's.

## How to judge an AI video model

Rankings change monthly; the things that make a clip usable do not. Judge any model on these six, in this order.

1. **Does it follow the prompt?** Not "is it pretty" but "is it the shot I described": subject, action, camera move, exclusions. Prompt adherence is the biggest gap between the top of the leaderboard and the middle.
2. **Does the world hold together?** Hands, teeth, fabric, water, and objects passing in front of each other. Physics failures are what make a viewer say "that's AI" before they can say why.
3. **Does the character survive the clip?** Faces drift, jackets change colour, hair changes length. Models with reference inputs (a photo you supply) hold up far better than text alone.
4. **Does it make sound?** Native audio, meaning dialogue, ambience and effects generated with the picture, went from a Veo party trick to table stakes in a year. A silent model costs you a second tool.
5. **How long is a clip, and can you extend it?** 5 seconds was standard in 2025. The current range is 8 to 30 seconds, with some models chaining clips while keeping the character.
6. **What does a usable second cost?** Not the headline rate: the rate at the resolution you will publish, multiplied by the takes you need to get a keeper.

The quality bar is best measured by a third party. [Artificial Analysis](https://artificialanalysis.ai/) runs a blind, head-to-head arena where people vote on paired clips, and most of the comparison sites quote it. Two cautions: its text-to-video board was reset to a new version this summer, so scores quoted from spring are on a different scale, and the arena measures preference, not prompt adherence on your specific job. Use it to shortlist, then test.

## October 2026 at a glance

Figures are from each vendor's pages and the comparison sources listed at the end, checked the week of 8 October 2026. Prices are per second of output through the cheapest public API or reseller we could find, and they move; treat them as the order of magnitude.

| Model | Best for | Max clip | Resolution | Price per second | Status, October 2026 |
|---|---|---|---|---|---|
| **Seedance 2.5** (ByteDance) | Prompt adherence, long multi-reference clips | 30s | 480p–1080p via resellers | ~0.10 (480p) to 0.61 (1080p) | Released July 2026; via Runway, fal, Higgsfield, Runware |
| **Wan 3.0** (Alibaba) | Top of the leaderboard, motion realism | 30s | up to 1080p | ~0.05–0.20 | API only; no weights |
| **Gemini Omni Flash** (Google) | Cheap, fast, multimodal input | 10s | 720p | ~0.10 | Public preview since June; replaced Veo in the Gemini app and Flow |
| **Veo 3.1** (Google) | Cinematic realism, synced audio, 4K | 8s, extendable | native 4K | ~0.15 (Fast) to 0.40 (Standard) | Still on the Gemini API and Vertex: Quality, Fast, Lite |
| **Kling 3.0** (Kuaishou) | Stylised storytelling, multi-shot sequences | 15s per shot | native 4K, up to 60 fps | ~0.08–0.17 | Global since March 2026 |
| **MiniMax H3** | Open weights with stereo audio | 15s | up to 2K | ~0.13 hosted; free to self-host | Weights on Hugging Face, community licence |
| **Runway Gen-4.5** | Ideation inside a full editing suite | 10s presets | 1080p | ~0.12–0.25 | Current since December 2025; Runway also resells Seedance and Wan |
| **Wan 2.2 / 2.7** (Alibaba) | Self-hosting (2.2), cheap API (2.7) | 15s | 1080p | 2.7 from ~0.10 | 2.2 is Apache-2.0 open weights; 2.5 onward API only |
| **Sora 2** (OpenAI) | — | — | — | — | App closed 26 April 2026; API closed 24 September 2026 |

Prices are in US dollars per second of output. Every live model in the table generates audio with the picture (HunyuanVideo 1.5, in the open-weight section, does not). Where a vendor publishes no rate, as ByteDance does not for Seedance 2.5, the figure is what resellers charge, and we quote the one we paid.

## The models, one by one

### 1. Seedance 2.5: the one to test first

ByteDance announced Seedance 2.5 in June and opened access through partners over July. It is the model most lists now put first for commercial work, and after a day with it we understand why.

**What stands out.** Adherence. We gave it eight shot descriptions for our own preview pages, from a rain-soaked alley to a product unboxing from above, and seven came back as described on the first render, including a parenthetical about neon signs showing "abstract shapes, no readable text" that it respected. Clips run to 30 seconds with audio, and the reference budget is unusually large: up to 30 images, 10 clips and 10 audio files to anchor a character, a product or a voice. That is what makes it practical for a product video, where the thing in the shot has to look like the thing you sell.

**Limitations.** Availability is the catch. ByteDance's own API is not offered in the US, so you reach it through Runway, fal, Higgsfield, Runware and similar. Each sets its own price and resolution tiers, and there is no official rate to compare against. The one that failed for us was a sneaker "floating in coloured smoke": the shoe came out tiny in an empty frame, a reminder that small subjects need a camera distance spelled out. Sits at #3 on the text-to-video arena as of 8 October.

### 2. Wan 3.0: top of the leaderboard, hard to reach

Alibaba's Wan 3.0 holds first place on the Artificial Analysis text-to-video board this month, ahead of Seedance 2.5. It is also the model most people have never opened.

**What stands out.** Motion and physics: Wan has been the "things move correctly" family since 2.5, and 3.0 extends that to 30-second clips with native audio. Pricing through the APIs that carry it is the lowest in this list at the 480p tier.

**Limitations.** There are no published weights for 2.5, 2.7 or 3.0, despite the family's open-source reputation; the open one is Wan 2.2, which is a different, older model. Access is through Alibaba Cloud and a handful of resellers, documentation is thinner in English, and we have not generated with it ourselves, so everything here is second-hand.

### 3. Gemini Omni Flash: Google's new default

At I/O in May, Google announced Gemini Omni, a multimodal model that takes text, images, video and audio in and produces video out. Omni Flash replaced Veo inside the Gemini app and Flow in June. If you use Google's consumer tools, this is what you are already getting.

**What stands out.** Cost and speed. At roughly a tenth of a dollar per second, with audio, it is the cheapest of the big-name models and the quickest to return a clip. It led the text-to-video arena in July before the benchmark reset and still sits near the top for image-to-video. It is the right model for volume: social variations, drafts, anything you will iterate on ten times.

**Limitations.** Ten seconds and 720p in Flow. For a hero shot or anything that will be shown large, you will want Veo 3.1 or Seedance 2.5 instead. Treat it as the draft model and the social model, not the master.

### 4. Veo 3.1: still the cinematic pick

Veo did not go away when Omni arrived. Veo 3.1 remains on the Gemini API and Vertex AI in Quality, Fast and Lite tiers, all with native audio, and it is the model to reach for when the clip has to look like film.

**What stands out.** Light, lenses and sound. Veo's output has the most convincing depth of field, specular highlights and synced audio of anything we have used, and it is the only model here with native 4K on the base clip. We generated five product clips with Veo 3.1 Fast this month, including a pair of headphones turning on a lit pedestal and a bottle caught in a slow-motion splash, and the material and reflections held up at full size.

![Four clips we generated with Veo 3.1 Fast in October 2026: headphones on a glowing pedestal, a ceramic kettle on a sunlit counter, a frosted bottle in a splash of water, and hands opening a gift box from above](https://exemplary.ai/img/blog/ai-video-generation-models-2026/veo-samples.jpg)

**Limitations.** Eight seconds per generation, extendable by chaining but dropping to 720p when you do. It is also the most expensive per second in the table at the Standard tier, and its arena score has fallen behind the newer Chinese models on prompt adherence. The watch we rendered came back with invented lettering on the dial, which is the general Veo caution: say "no text" or expect some.

### 5. Kling 3.0: the storyteller

Kuaishou announced Kling 3.0 in February and rolled it out globally in March. Where Seedance wins single shots, Kling wins sequences.

**What stands out.** Multi-shot generation, up to six scenes in one job with a character that persists between them, lip-synced dialogue in five languages, and native 4K at up to 60 fps for anyone who needs the frame rate. Pricing is mid-pack and lower on Kling's own platform than through resellers. It is the model for a short narrative, an explainer with a recurring presenter, or anything stylised.

**Limitations.** Its arena scores sit well below Seedance and Wan on raw text-to-video, so a one-line prompt gets a more generic result than the same prompt in Seedance. Kling rewards structure: a shot list, references and a script. A 4.0 has been rumoured for this autumn; as of this writing it has not shipped, and we would not plan around it.

### 6. MiniMax H3 and the open-weight tier

For the first time, self-hosting is a serious option rather than a hobby.

**What stands out.** MiniMax H3 is 33 billion parameters, generates native stereo audio, reaches 2K and 15 seconds, and ships under a community licence that allows commercial use. A fine-tuned version ranks in the arena's top five. Wan 2.2 is Apache-2.0 and the most widely used open model, with a 5-billion-parameter variant that runs on a 24 GB consumer card. LTX-2.5 (19 billion, native audio, free under 10 million dollars of annual revenue) and HunyuanVideo 1.5 (8.3 billion, no audio, runs in 14 GB with offloading) round out the set.

**Limitations.** The cost moves from the invoice to the GPU bill and the engineer's time, and the hosted versions of the same models are often cheaper per clip than renting the hardware for occasional use. Open weights matter most if you need the model inside your own infrastructure, want to fine-tune on your own footage, or generate at a volume where per-second pricing hurts.

### 7. Runway Gen-4.5: the editor's model

Runway's Gen-4.5 shipped in December 2025 and remains its flagship, but Runway's story this year is the suite around it: Aleph 2 for editing existing footage with up to five keyframes, and a platform that now resells Seedance 2.5 and Wan 3 alongside its own model.

**What stands out.** Workflow. If your team already edits in Runway, generating there keeps everything on one timeline, and Aleph 2's video-to-video editing (change the weather, swap the background, restyle a shot) is the most practical tool of its kind.

**Limitations.** Gen-4.5's launch-day leaderboard score was self-reported on a scale that has since been retired, and the model does not appear on the live boards. On pure generation it is a tier behind the models above, which is presumably why Runway now sells them too.

### What happened to Sora

Sora 2 launched on 30 September 2025 with native audio and a social app, and for a few months it was the consumer face of AI video. In March 2026 OpenAI announced a two-stage shutdown: the app and web product closed on 26 April, and the API followed on 24 September. No successor has been announced. Any guide, plugin or tool that still offers "Sora" is routing to something else or has not been updated; ask which.

## Choose a model in thirty seconds

- **A product shot or an ad where the thing must look like the thing:** Seedance 2.5, with your product photos as references.
- **A cinematic hero clip, a film look, or anything shown at 4K:** Veo 3.1.
- **A short story, an explainer with a presenter, or a multi-shot sequence:** Kling 3.0.
- **Social variations, drafts, ten takes to find one:** Gemini Omni Flash.
- **Motion-heavy scenes, if you can reach it:** Wan 3.0.
- **Inside your own infrastructure, or fine-tuned on your footage:** MiniMax H3 or Wan 2.2.
- **Editing footage you already have rather than generating new:** Runway Aleph 2.

## Why the serious workflows use more than one

Nobody shipping video at volume uses one model. The pattern that works: draft the prompt at 480p on the cheapest model that follows instructions well, lock the shot, then render the final take once on the model whose look you want. A product video might be referenced in Seedance, have its hero shot rendered in Veo, and be cut together with captions and a voiceover in a tool that was never a generator at all.

That last step is the one the model lists skip. A generated clip is raw footage. It still needs captions (most short video is watched muted), a cut, maybe a translation, and a version for each aspect ratio. [Auto captions](https://exemplary.ai/auto-subtitle-generator) and [subtitle translation](https://exemplary.ai/subtitle-translator) already do that part for any clip, from any model, today.

It is also why we are building our [AI video generator](https://exemplary.ai/ai-video-generator) to route to models rather than be one: a prompt or a script goes to the model that fits the shot (Veo 3.1 and Kling 3 are the first two families), the price is shown before anything renders, and the output lands on the same timeline as your own footage and captions. It opens in December 2026; the page has previews and a waitlist.

## Frequently asked questions

**Which AI video model is the best right now?**
On the public leaderboard, Wan 3.0 and Seedance 2.5 lead for text-to-video as of October 2026. For most people Seedance 2.5 is the better first choice because it is reachable through several Western resellers and follows prompts closely. "Best" still depends on the job; see the list above.

**Is Sora still available?**
No. The Sora app closed on 26 April 2026 and the API on 24 September 2026. OpenAI has not announced a replacement.

**What replaced Veo in Google's apps?**
Gemini Omni Flash, in June 2026. Veo 3.1 is still available to developers on the Gemini API and Vertex AI, in Quality, Fast and Lite tiers.

**Which model is cheapest?**
Per second, Wan 3.0 at 480p and Gemini Omni Flash are the cheapest of the major models at around five to ten cents. The cheapest usable second is a different question: a model that needs five takes costs more than one that needs two.

**Which models make sound?**
Seedance 2.5, Wan 3.0, Gemini Omni Flash, Veo 3.1, Kling 3.0, MiniMax H3 and Runway Gen-4.5 all generate audio with the picture. HunyuanVideo 1.5 does not.

**Can I run a video model on my own hardware?**
Yes. MiniMax H3, Wan 2.2, LTX-2.5 and HunyuanVideo 1.5 have published weights. Wan 2.2's 5-billion-parameter variant runs on a 24 GB GPU; the larger models want an 80 GB card.

**How long can a clip be?**
Eight seconds on Veo 3.1 (extendable), ten on Gemini Omni Flash, fifteen on Kling 3.0 and MiniMax H3, and thirty on Seedance 2.5 and Wan 3.0.

**Do I have to say a video is AI-generated?**
If it shows people or events that did not happen, yes, and several platforms now require a label. Every preview on our own pages carries one. Audiences forgive a label far more readily than a discovery.

## Sources and method

Specifications, dates and prices were checked the week of 8 October 2026 against vendor documentation (Google's Veo and Gemini pages, Runway's changelog and pricing, Kling's documentation, the MiniMax, Wan, LTX and Hunyuan repositories on Hugging Face and GitHub) and cross-checked against three independent comparison pages: [rizzgen's model comparison](https://www.rizzgen.ai/blogs/runway-kling-veo-ltx-wan-seedance-comparison) (updated 8 October 2026), [VideoGen's ranked list](https://videogen.io/best-ai-video-models) and the [Machine Learning Guide's 2026 video episode](https://ocdevel.com/mlg/mla-26) (updated 13 September 2026). Arena positions are from [Artificial Analysis](https://artificialanalysis.ai/). The Seedance 2.5 and Veo 3.1 Fast observations are our own, from clips generated for our preview pages in October 2026 through Runware and Adobe Firefly; the Seedance price we quote is the rate we paid there. We have not generated with Wan 3.0, Kling 3.0, MiniMax H3 or Gen-4.5 ourselves, and we say so where it matters.
