April 28, 2026 Update: HappyHorse 1.0 is now available through GPTImage2. The shortlist table and HappyHorse section have been updated to reflect live API access.
If you are searching for the best AI video model in 2026, the wrong first step is to look for one universal winner in GPTImage2's model catalog.
The better first step is to build a shortlist by workflow, then move from article to route page.
This article answers one question only:
Which AI video model families should a serious team shortlist in 2026?
It is a shortlist article, not a Seedance 2.0 launch-watch page.
Shortlist First
| If your main need is... | Start with |
|---|---|
| Lowest live per-second entry price | Seedance 1.5 Pro |
| Prompt-first short-form generation | Kling 3.0 |
| Reference-guided or edit-oriented workflows | Kling O3 |
| Premium realism and official vendor clarity | Sora 2 |
| Fixed per-video budgeting | Veo 3.1 Lite, Hailuo 2.3, Hailuo 02, Grok Imagine Video |
| Alibaba family continuity | Wan 2.6 or Wan 2.5 |
| Testing the newest top-tier challenger | HappyHorse |
What This Guide Includes
This guide focuses on model families that are useful to shortlist because they represent meaningfully different production choices:
- per-second vs per-video billing
- prompt-first vs reference-first workflows
- premium realism vs throughput efficiency
- family continuity vs new-route adoption
Shortlist Table
| Model | Provider | Billing shape | Main workflow | Starting price | Why shortlist it |
|---|---|---|---|---|---|
| Seedance 1.5 Pro | BytePlus | Per second | Low-cost baseline generation Modes: text-to-video, image-to-video | $0.0247/s | Best live entry point when lowest listed per-second price matters most |
| Kling 3.0 | Kling | Per second | Prompt-first short-form generation Modes: text-to-video, image-to-video | $0.075/s | Strong default shortlist choice for repeatable 3-15 second content production |
| Kling O3 | Kling | Per second | Reference-to-video and video edit Modes: text-to-video, image-to-video, video edit, reference video | from $0.075/s | Shortlist when reference-driven generation or editing is central to the workflow |
| Sora 2 | OpenAI | Per second | Premium realism-oriented generation Modes: text-to-video, image-to-video | $0.08/s | Shortlist when realism, premium polish, and cleaner vendor documentation matter most |
| Sora 2 Pro | OpenAI | Per 10s | Higher-tier premium video work Modes: text-to-video, image-to-video | from $0.6389/10s | Shortlist only when higher-end output justifies the much steeper pricing tier |
| Veo 3.1 | Mixed: Lite per video, Preview per second | Short-clip planning Modes: text-to-video, image-to-video, preview audio variants | from $0.1681/video Lite or $0.10/s Preview | Useful shortlist entry when you may want either fixed per-clip Lite budgeting or audio-aware Preview workflows | |
| Hailuo 2.3 | MiniMax | Per video | Simple fixed-price generation Modes: text-to-video, image-to-video | $0.25/video | Worth shortlisting when fixed per-video billing is easier to explain internally |
| Hailuo 02 | MiniMax | Per video | First-last-frame workflows Modes: text-to-video, image-to-video | $0.25/video | Relevant shortlist route for teams that need more frame-anchored control |
| Grok Imagine Video | xAI | Per video | Lowest fixed per-video entry Modes: text-to-video | $0.0639/video | Worth shortlisting when the lowest fixed clip entry cost is your first filter |
| Wan 2.6 | Alibaba | Per second | Alibaba family standardization Modes: text-to-video, image-to-video, reference video | from $0.0708/s | Useful shortlist route when your team wants the newer Wan family with multiple workflow entries |
| Wan 2.5 | Alibaba | Per second | Legacy family continuity Modes: text-to-video, image-to-video | $0.0708/s | Still worth shortlisting if compatibility matters more than upgrading families immediately |
| HappyHorse 1.0 | TBD | Per second | Text-to-video and image-to-video generation Live on GPTImage2 | See model page | Currently ranked No. 1 on the Artificial Analysis Text-to-Video Leaderboard. Worth testing when quality-first output is the first filter |
How To Shortlist By Workflow
1. If entry cost is your first filter
Start with Seedance 1.5 Pro for the lowest live listed per-second entry price.
Use Grok Imagine Video if you want the lowest fixed per-video starting point.
2. If your workflow is prompt-first
Start with Kling 3.0. It is the cleanest shortlist entry for repeatable prompt-first short video work.
3. If your workflow is reference-first or edit-first
Start with Kling O3. It is the clearest shortlist choice when control and editing matter more than a simpler prompt-only route.
4. If realism matters most
Start with Sora 2. It is the best shortlist entry when your bar is premium realism rather than lowest cost or highest throughput.
5. If finance wants simpler forecasting
Start with the clearest fixed-price families:
- Grok Imagine Video
- Hailuo 2.3
- Hailuo 02
If you still want Veo 3.1, use Lite routes for per-video budgeting and Preview routes for per-second, audio-aware planning.
6. If you want one family to grow inside
Use Wan 2.6 if you want the newer Alibaba family.
Use Wan 2.5 if you care more about compatibility than about moving families right now.
Quick Routing Table
| Workflow need | Better first pick | Why |
|---|---|---|
| Lowest live listed per-second start | Seedance 1.5 Pro | Lowest currently listed live per-second entry price |
Prompt-first 3-15 second clips | Kling 3.0 | Clear 3-15 second billing and prompt-first entry point |
| Reference-to-video | Kling O3 or Wan 2.6 Reference Video | Both expose explicit reference-oriented routes |
| Video editing | Kling O3 | Explicit video edit route in the current catalog |
| Motion transfer | Kling 3.0 Motion Control | Explicit motion-transfer workflow |
| Fixed-price budgeting | Grok Imagine Video, Hailuo 2.3, Hailuo 02, Veo 3.1 Lite | These options use fixed per-video or Lite-route pricing |
What About HappyHorse?
HappyHorse 1.0 is currently ranked No. 1 on the Artificial Analysis Text-to-Video Leaderboard (No Audio), above Seedance 2.0 in the public snapshot as of April 2026.
It is now available through GPTImage2 for API testing. Treat GPTImage2 pricing and access as route-specific, and keep official vendor, GitHub, and open-source claims separate until they are clearly documented.
That makes it a real shortlist contender — especially for teams currently choosing between Seedance 2.0 and Sora 2 for quality-first workflows.
What to do now:
- Test the model on the HappyHorse page
- Use the release-watch blog post for source-trust, GitHub, and open-source questions
- Compare it against Seedance, Kling, Sora, and Veo with your own prompts before choosing a default route
Why A Shortlist Beats A Winner List
AI video models do not solve the same problem in the same way.
Some are better because they are:
- cheaper
- easier to route
- easier to budget
- better at realism
- better at reference-driven control
That is why the right decision is usually a shortlist, not a champion.
Why This Matters On GPTImage2
This is exactly where GPTImage2 should be strongest.
The point of a shortlist is not to make users memorize model brands. It is to help them decide:
- which family to test first
- which family to route to for each workload
- how to avoid rebuilding integrations every time the shortlist changes
That is why a unified API gateway matters here. The operational win is not just access to more models. It is keeping model choice flexible while keeping integration overhead stable.
The next practical step is to move from shortlist to route page: open the full model directory, then compare specific routes like Seedance 1.5 Pro, Kling 3.0, Kling O3, Sora 2, and Veo 3.1.
View All Models on GPTImage2What This Guide Does Not Claim
This guide intentionally does not claim:
- which model is "best overall" for realism
- which model is fastest end-to-end in your region
- which model has the strongest native audio quality
- any blanket provider discount percentage across all families
- any winner claim that is not backed by your own eval set
If your production choice depends on visual fidelity, camera consistency, audio, or moderation behavior, run the same prompts across your short list and compare outputs under your own success criteria.
