Best AI Video Models 2026: Seedance, MiniMax H3, Gemini Omni

Last updated: September 28, 2026. Looking for last year's head-to-head of Veo 3.1, Kling 2.6, Wan 2.6, Seedance 1.5 and Sora 2? That's still here: AI Video Model Comparison 2025.

Three releases shaped AI video in 2026 more than anything else: ByteDance's Seedance 2.5, MiniMax's H3, and Google's Gemini Omni. They go after different problems. Seedance 2.5 is about long single takes. MiniMax H3 is about resolution and, in its Max version, speed. Gemini Omni puts four short-video jobs into one model.

This guide goes through each of them in some depth, then covers the other models we'd still reach for. Every spec and credit price here comes from the model settings on Dreamega as of the date above. We didn't run our own benchmarks, so there are no invented scores. When a vendor hasn't published something, we say so.

Why these three matter

• Seedance 2.5 made 30-second shots normal. It renders up to 30 seconds in one pass with no stitching, and it takes up to 50 reference files in a single request. Last year's models mostly stopped at 10 to 15 seconds.
• MiniMax H3 took over from Hailuo. The standard model renders only at 2K. H3 Max, fal's post-trained version, trades that for speed: fal says a 5-second clip comes back in about 3 seconds.
• Gemini Omni is Google's all-in-one short-video model. Text-to-video, image-to-video, reference-to-video and video editing all sit under one name, and every clip comes with synchronized sound.

Seedance 2.5 (and what's left of 2.0)

Seedance 2.5 is ByteDance's current flagship video model. It was unveiled at Volcano Engine FORCE 2026. The headline feature is a native 30-second one-shot: you set any length from 4 to 30 seconds, and the model renders it as one continuous take, scene changes included.

What you get

Native audio is on by default in every mode. Text-to-video accepts up to 30 reference images, 10 reference videos and 10 audio tracks, which is where the "50 references" figure comes from. Adding reference videos costs extra, from 11 credits per output second at 480p up to 110 at 4K. On Dreamega, 480p is available on every plan. 720p and above on the standard model need a Pro plan. Turbo's 720p tier does not.

Where it's strong

• Long takes. A 30-second shot is one generation, not three clips glued together, so lighting and characters don't jump at the seams.
• Lots of control. Few models let you feed in this many images, videos and audio tracks at once.
• Turbo is the real bargain. 1080p Turbo costs 22 credits per second, only a little more than the standard model at 480p (18). If you don't need 4K, start with Turbo.

Limits

• Full quality gets expensive fast. Standard 1080p is 90 credits per second, so a 30-second 1080p take costs 2,700 credits. The same take at 4K is 5,400.
• Turbo has no 480p or 4K. It's 720p or 1080p only.
• Spicy tops out at 15 seconds and is image-to-video only.

Spicy, Reference and the 2.0 family

Seedance 2.5 Spicy is an image-to-video tier tuned for more expressive, higher-energy motion. The Seedance 2.0 Spicy tier works the same way, and there Spicy refers to the intensity of the motion and grading, not the subject matter. Seedance 2.5 Reference takes up to 30 images, 4 videos and 2 audio tracks, and you point to each one in the prompt by position: [Image1], [Video1], [Audio1].

Seedance 2.0 is still available and still useful for drafts. Seedance 2.0 Mini is 12 credits per second at 480p (60 for 5 seconds), and 2.0 Mini Turbo is 14 per second at 720p with audio. Both stop at 15 seconds.

Best for

Long continuous shots, music-driven edits, multi-character scenes that need references, and anything you'd otherwise have to stitch together.

Prompt tips

• Write the 30 seconds as beats in order ("opens on…, then…, ends with…"). The model handles tempo changes inside one take, but it needs to know where they are.
• In Reference mode, name what each file is for: "[Image1] is the lead actor, [Image2] is her jacket, [Video1] sets the camera move."
• Draft at 480p or on Turbo, lock the prompt, then render the final at 1080p or 4K.

MiniMax H3 and H3 Max

MiniMax H3 is MiniMax's newest video model family. On Dreamega there are two versions, and they're more different than the names suggest.

MiniMax H3

Text-to-video has six aspect ratios, from 21:9 down to 9:16. Image-to-video takes a first frame plus an optional last frame, so you can decide where the shot lands. Reference-to-video takes up to 9 images, 3 video clips and 3 audio tracks. The first five reference images are free and each extra one is 8 credits. Each reference video clip (up to 5 seconds) adds 130 credits, and reference audio is free.

MiniMax H3 Max

H3 Max is the same H3 base model with extra post-training from fal Research, aimed at prompt adherence and visual quality. fal reports that a 5-second clip returns in about 3 seconds, with roughly 35 times the throughput of MiniMax's own H3 endpoint. In fal's human-preference evaluation against twelve models, including Seedance 2.5, Gemini Omni Flash, Kling 3 and Veo 3.1, it ranked first for overall quality. That's fal's own test, so read it as a claim, not a settled result.

Every H3 Max clip comes with synchronized audio at no extra charge. 768p is the model's native tier (1344×768 at 24 fps for 16:9). 1080p is a refinement from that 768p source. 480p is open on every plan, and 768p and 1080p need Pro.

Where they're strong

• H3: every clip renders at 2K, with wide 21:9 framing and first-and-last-frame control.
• H3 Max: 1080p with sound for 16 credits per second is one of the lowest prices for 1080p with audio on Dreamega, and it's fast enough to iterate in near real time.

Limits

• H3's settings on Dreamega don't list audio output, so plan on adding sound yourself or use H3 Max.
• H3 has no lower resolution tiers, so every draft costs the full 26 credits per second.
• H3 Max has no reference-to-video mode and stops at 1080p.
• Both max out at 15 seconds.

Best for

H3 for widescreen 2K shots and first-to-last-frame transitions. H3 Max for quick drafts, social clips with sound, and anything where you'll iterate a lot.

Prompt tips

• H3 image-to-video responds to plain motion instructions ("slow push-in, she turns toward the window"). Keep it to one or two actions per clip.
• Use the last-frame option for loops and transitions. Try the same image as first and last frame when you want the clip to cycle.
• On H3 Max, draft at 480p (25 credits for 5 seconds), then re-run the winning prompt at 1080p.

Google Gemini Omni Flash

Gemini Omni 1.1 Flash is Google's fast, omnimodal short-video model. "Omni" means one model covers four jobs:

Every clip includes synchronized native audio: dialogue, ambience and sound effects. Output is 16:9 or 9:16. Google hasn't published an output resolution for this model, so we don't list one. There's no resolution setting to pick, and no mode is locked behind a Pro plan.

Where it's strong

• One place for the whole loop. You can generate a clip, animate a product photo, keep a character consistent with reference images, then fix the lighting with a text edit, all with the same model.
• Sound is always included, and it's billed in the per-second price.
• 9:16 is one of its two formats, which suits Reels, Shorts and TikToks.

Limits

• 10 seconds is the ceiling. For longer shots, look at Seedance 2.5 or Wan 3.0.
• Only two aspect ratios. No 1:1, no 21:9.
• It's not the cheapest Google option. Veo 3.1 Fast costs 15 credits per second at 1080p against Omni's 20, and Veo goes up to 4K. Omni's advantage is having generation, references and text-based editing in one model, not the price.
• No published resolution, so if you need guaranteed 1080p or 4K deliverables, use a model that states it.

Best for

Social content, quick prototypes, product shots animated from a photo, and small fixes to a clip you already have.

Prompt tips

• Pick 9:16 up front for mobile. Cropping a 16:9 clip later loses a lot.
• In reference mode, use clean images of the subject on a plain background. Up to four are allowed, and different angles help more than near-duplicates.
• For video edit, describe only the change ("make it dusk, add rain on the window"). The edit is meant to keep the original motion and framing.

Other models worth knowing in 2026

These aren't the focus of this article, but you'll run into them, and each one still wins in its own lane.

• Veo 3.1 (Google): 4, 6 or 8 seconds, native audio, up to 4K. Standard is 40 credits per second at 720p or 1080p, and Fast is 15. Still our first pick when people talk on camera.
• Kling 3.0 and Kling O3 (Kuaishou): 3 to 15 seconds, with Standard, Pro and 4K tiers. Kling 3.0 Standard is 126 credits for 5 seconds with sound on (the default). O3 has sound off by default (84 for 5 seconds) and adds multi-shot generation and reference-based subjects.
• Wan 3.0 (Alibaba): 2 to 30 seconds with native audio, at 11, 20 or 42 credits per second for 480p, 720p and 1080p. It's the cheaper way to get a 30-second shot. A 30-second 720p clip is 600 credits, compared with 1,080 on standard Seedance 2.5 (Seedance 2.5 Turbo is also 600).
• Sora 2 (OpenAI): 4, 8 or 12 seconds with synchronized audio. Standard is 720p at 10 credits per second, and Pro goes up to 1792×1024 at 30.
• HappyHorse 1.0 (Alibaba): a roughly 15B-parameter single-stream transformer that took the top spot on the Artificial Analysis video leaderboard in April 2026. 3 to 15 seconds at 720p (20/s) or 1080p (35/s). Our settings don't list native audio for it.
• Vidu Q3 (Shengshu): 1 to 16 seconds with audio and background music, up to 1080p. 35 credits for a 5-second 540p draft, 80 for 5 seconds at 1080p.

Side-by-side comparison

Prices are Dreamega credits for one 5-second clip unless noted. "Pro" means that tier needs a Pro plan.

Which one should you pick?

• One long take, 20 to 30 seconds: Seedance 2.5 (Turbo if you don't need 4K), or Wan 3.0 at 480p for the cheapest version.
• 1080p with sound on a budget: MiniMax H3 Max at 16 credits per second.
• Widescreen 2K and first-to-last-frame shots: MiniMax H3.
• Vertical social clips, quick edits, reference-based characters: Gemini Omni.
• People talking to camera: Veo 3.1.
• Precise motion or 4K from Kuaishou: Kling 3.0 or Kling O3.

A habit that saves more credits than picking the "best" model: draft on the cheapest tier that shows you the motion, lock the prompt, and only then pay for resolution.

FAQ

What is the best AI video model in 2026? There isn't one winner. Seedance 2.5 is the pick for long single takes and heavy use of references. MiniMax H3 Max gives the best price for 1080p with sound. Gemini Omni is the most flexible for short clips and edits. Veo 3.1 is still the strongest for realistic people talking.

What's the difference between Seedance 2.5 and Seedance 2.0? Seedance 2.5 goes up to 30 seconds in one pass (2.0 stops at 15), accepts up to 50 references (2.0 takes 9 images, 3 videos and 3 audio tracks), and costs less per second at every resolution. For example, 720p is 36 credits per second on 2.5 and 48 on 2.0.

Is MiniMax H3 the same as Hailuo? No. H3 is MiniMax's newer model family. Hailuo 2.3 is still on Dreamega, but it doesn't generate sound and it tops out at 10 seconds. For new work, use H3 or H3 Max.

Is Gemini Omni the same as Veo? No. Both come from Google, but Veo 3.1 is a dedicated video model with resolutions up to 4K, while Gemini Omni Flash is a fast multimodal model for 3 to 10 second clips that also edits existing video.

Which of these models generate sound? Seedance 2.5 (all modes), MiniMax H3 Max and Gemini Omni all generate synchronized audio. The standard MiniMax H3 settings on Dreamega don't list audio.

Can I try them for free? New Dreamega accounts get free credits through the daily check-in. The lowest-cost entry points here are MiniMax H3 Max at 480p (25 credits for 5 seconds) and Wan 3.0 at 480p (55 credits), and Seedance 2.5 at 480p and all Gemini Omni modes don't need a Pro plan.
