The Best Sora Alternatives After OpenAI Shut Sora Down

If you opened the Sora app this spring and found a goodbye message, you weren't imagining it. OpenAI announced on March 24, 2026 that it was discontinuing Sora. The app and website shut down on April 26, and the API followed on September 24.

Sora isn't coming back, but you have plenty of options. The months since have been the busiest stretch AI video has ever had. ByteDance, Kuaishou, Google, Alibaba, and MiniMax all shipped new models, and several of them do things Sora never could, like generating 30 seconds in one continuous take or editing a clip just by talking to it.

Below are six models worth your time: what each one is actually good at, where it trips up, and what it costs. All six are available on AI Studio, so you can run the same prompt through every one of them from a single account instead of signing up six times.

The short version

Clip lengths are the makers' stated limits as of early November 2026. Platforms that resell these models sometimes offer a narrower range, so check the generator you're using.

1. Seedance 2.5: the one-take specialist

ByteDance officially launched Seedance 2.5 on July 31, 2026. The headline is length: one generation produces up to 30 seconds of video with synchronized audio, double what its predecessor could manage in a single pass.

That matters more than it sounds. Most AI video still looks like a string of short clips stitched together, and you can feel the seams. Thirty unbroken seconds is enough for a full product demo, a music-video verse, or a short scene with a beginning, middle, and end.

It's also built for directors who like to control things:

• Lots of references. ByteDance says one generation can take up to 30 images, 10 video clips, and 10 audio clips.
• Timestamped prompts. You can say what happens from 0 to 5 seconds, then 5 to 12, and so on.
• 3D blockouts. You can rough out a scene with plain, untextured 3D models (ByteDance calls this a "clay render"), and the model uses that layout for poses, motion paths, and camera angles.
• Targeted edits. Green-screen editing, changing the camera perspective, and editing specific moments by timestamp.

Where it struggles: ByteDance's own launch post admits room for improvement on the physics of complex motion and on keeping scenes stable when several characters interact. If your shot is a crowded fight, expect to reroll.

What it costs: ByteDance's launch post didn't include a public price list. At launch it was rolling out in ByteDance's Jimeng and Doubao apps, with API access through BytePlus ModelArk described as "coming soon."

On AI Studio: The Seedance 2.5 AI video generator offers 4 to 30 seconds, 480p to 1080p, up to 30 reference images, and audio that's on by default. A good habit is drafting at 480p and rendering the keeper at 1080p.

Pick it if you want one long, smooth take with sound and you're happy to write a detailed, time-coded prompt.

2. Kling 4.0: the planner's model

Kuaishou's Kling 4.0 arrived in two steps. A preview called Kling 4.0 Flash opened to some subscribers on September 28, 2026, and the full model followed in October.

Like Seedance 2.5, it generates 3 to 30 seconds natively. What sets it apart is keyframes. According to Kling's own guide, published September 30, you can give it up to 10 keyframe images in a single generation: the opening shot, the product reveal, the moment the lights change, the ending. The prompt then explains how the video gets from one to the next. Kling also lists up to 15 reference assets per task (images, videos, subjects, and voice) and prompts of up to 8,000 tokens.

If Seedance 2.5 is a camera operator who nails long takes, Kling 4.0 is a storyboard artist. It shines when you already know your beats.

Where it struggles: Spec lists differ by platform. Kling promotes features like 4K and HDR, but many third-party platforms, including AI Studio, currently offer 720p and 1080p. More keyframes also means more ways for transitions to go wrong. Kling's own advice is to change one major thing at a time.

What it costs: When I checked, I couldn't find an official per-second API price for Kling 4.0. Kling sells credit plans in its own app, and resellers set their own prices.

On AI Studio: The Kling 4.0 AI video generator offers 3 to 30 seconds, 720p or 1080p, 16:9, 9:16, 1:1, and 21:9 ratios, first- and last-frame control, and references of up to 10 images and 5 videos. AI Studio's page says credits for failed generations are returned automatically.

Pick it if you're making ads, explainers, or anything with a clear shot list.

3. Gemini Omni: the editor

Google DeepMind introduced Gemini Omni at Google I/O on May 19, 2026. Its trick isn't raw length. It's conversation.

You can mix text, images, audio, and video in a single prompt, then keep refining the result. Each instruction builds on the last, and characters, physics, and scene details carry over from one turn to the next. Instead of rerolling a shot from scratch because the lighting is wrong, you just ask for warmer light.

The August 27 update, Gemini Omni 1.1 Flash, added the controls creators had been asking for:

• Scene extension in 10-second steps, up to 40 seconds in total, using up to 10 seconds of the previous footage as context.
• First and last frames, so you can set where a shot starts and ends.
• 360p drafts that Google says generate up to 60% faster than 720p at about a third of the cost.
• 1080p and 4K output for finished work.

Every Omni video carries Google's invisible SynthID watermark by default, which matters if you publish where AI labeling rules apply.

Where it struggles: At launch, Flash clips were capped at 10 seconds per generation. Early hands-on testing by MindStudio found the API returning errors in the first days after the 1.1 update, and a breakdancing robot that lost its head mid-move. Environments and atmosphere looked strong. Characters in complicated motion were the weak spot.

What it costs: Google's Gemini API pricing page lists 720p video at roughly $0.10 per second on standard pricing.

On AI Studio: The Gemini Omni AI video generator now includes Gemini Omni 1.1 Flash, with 4 to 10 seconds, 720p, native audio, and up to 10 reference images.

Pick it if you'd rather fix a shot than regenerate it, or you want to build longer sequences step by step.

4. Happy Horse: the realist

Happy Horse has the best origin story on this list. It showed up anonymously on the Artificial Analysis video leaderboards in April 2026 and went straight to the top before anyone knew who made it. Bloomberg then reported that Alibaba was behind it.

According to DataNorth's launch coverage, it was built by Alibaba's Taotian Future Life Lab, a team led by Zhang Di, previously a technical architect of Kling. At debut it ranked first on Artificial Analysis for both text-to-video and image-to-video in the categories judged without audio.

What makes it interesting is how it handles sound. Happy Horse generates video and audio together in one pass, including dialogue, ambient noise, and sound effects, with native lip-sync in seven languages: English, Mandarin, Cantonese, Japanese, Korean, German, and French. If your video has a person talking to the camera, that's a big deal.

Where it struggles: Its leaderboard lead was a snapshot from its debut, and rankings in this space move monthly. Clip length is also more modest than the 30-second models.

What it costs: At launch on fal, Happy Horse cost $0.14 per second at 720p and $0.28 per second at 1080p, according to DataNorth's April 28 report.

On AI Studio: The Happy Horse AI video generator offers text-to-video, image-to-video, and reference-to-video at 3 to 15 seconds, in 720p or 1080p. It accepts up to nine reference images, which you refer to in the prompt as character1, character2, and so on. It costs 10 credits per second at 720p and 18 at 1080p, so a 5-second clip is 50 or 90 credits.

Pick it if your video centers on people: talking heads, spokesperson clips, dialogue scenes.

5. MiniMax H3: the open one

MiniMax released H3, which many people call Hailuo 3.0, on July 31, 2026. It makes clips of up to 15 seconds at up to 2K resolution with synchronized stereo audio, and it accepts text, images, video, and audio as inputs.

Its real distinction is open weights. GIGAZINE reported on August 3 that MiniMax had published the model on Hugging Face and ModelScope. That means a developer with serious hardware can run it themselves instead of renting it. "Serious" is the key word: according to the files in ComfyUI's repository, the diffusion model alone is about 21 GB and the text encoder another 27 GB.

It's competitive, too. In Artificial Analysis rankings reported by GIGAZINE in early August, H3 placed second for text-to-video with audio, behind Gemini Omni Flash, and third for image-to-video with audio.

Where it struggles: When GIGAZINE reported the release, the license terms weren't spelled out. Read the license before you build a commercial product on a self-hosted copy.

What it costs: If you run it yourself, you pay for hardware, not per clip. Hosted prices vary by provider.

On AI Studio: The MiniMax H3 AI video generator includes three versions in one tool. H3 offers 768p and 2K. H3 Max and H3 Max Turbo offer 480p and 768p, and Turbo is the cheapest. H3 also accepts up to five reference images and three reference videos.

Pick it if you want 2K output, or you're a developer who wants the option to self-host.

6. Seedance 2.0: the proven workhorse

Newer isn't always better for every job. Seedance 2.0, released in February 2026, generates about 15 seconds per pass, and it has had months of real-world use behind it.

It also has some baggage. Clips of real actors made with it went viral within days of release, and Disney and Paramount Skydance sent ByteDance cease-and-desist letters. ByteDance responded that it respects intellectual property and would strengthen safeguards.

The quality case is still strong, though. In the Artificial Analysis rankings GIGAZINE reported in early August, Seedance 2.0 placed first for image-to-video with audio, ahead of both Gemini Omni Flash and MiniMax H3.

Pick it if you want to animate a still image with sound and don't need 30 seconds. It's also on AI Studio. Just don't feed it famous faces or franchise characters.

How to choose in two minutes

• Need one long, unbroken take? Seedance 2.5 or Kling 4.0.
• Know your shot list in advance? Kling 4.0 and its keyframes.
• Want to fix and extend instead of starting over? Gemini Omni.
• People talking on camera? Happy Horse.
• Want to self-host, or need 2K? MiniMax H3.
• Animating a single image with sound? Seedance 2.0.

But honestly, the best test is your own prompt. Spec sheets can't tell you which model understands your idea of "golden-hour tracking shot." Write one prompt you care about, run it through two or three models in an AI video generator that hosts several of them, and compare the results side by side. Twenty minutes of that beats a week of reading comparison posts, including this one.

Moving over from Sora

Your old Sora library is gone. OpenAI said user data would be permanently deleted once the shutdown deadlines passed, according to The Decoder. If you exported your videos, keep the original files somewhere you control.

There's no exact replacement for Cameos. Sora 2's feature for putting yourself and friends into videos doesn't have a one-to-one equivalent. The closest substitute is reference images: Happy Horse takes up to nine on AI Studio, Gemini Omni 1.1 Flash up to 10, and Seedance 2.5 up to 30. Only use a real person's likeness with their permission.

Rewrite your prompts for longer clips. Sora-era prompts were written for short clips. With 30-second models, break your prompt into time segments, such as "0–8s: …, 8–20s: …, 20–30s: …," so the model knows what happens when.

If you build products, don't depend on a single model. Sora's shutdown was a lesson in vendor risk. Keep the model behind a switch in your code so that changing providers is a configuration change, not a rewrite.

Respect other people's characters. Sora and Seedance 2.0 both drew legal fire over copyrighted characters and real people's likenesses. Original characters are safer, and frankly more interesting.
