AI video generation changed fast in 2026. Four models now lead the pack: Gemini 3.1 Pro Video from Google, GPT-5.4 from OpenAI, Wan2.7 from Alibaba, and Seedance 2.0 from ByteDance. Each solves different problems for creators. Pick the wrong one, and you waste time and money.
This guide compares them side by side. You will see what each model can actually do, not just marketing talk. Let's find the right tool for your workflow.
GPT-5.4 is a brain for planning videos, not a direct video generator. Gemini, Wan2.7, and Seedance 2.0 are native video engines. They create clips from text or images.
If you want to automate your editing software, pick GPT-5.4. If you want to generate footage directly, pick one of the other three.
| Model | Developer | Release Date | Core Strength | Primary Output |
|---|---|---|---|---|
| Gemini 3.1 Pro Video | Feb 2026 | All-in-one multimodal, native video and audio | Video clips, SVG animation, music | |
| GPT-5.4 | OpenAI | Mar 2026 | Reasoning, planning, computer control | Workflow orchestration, not direct video |
| Wan2.7 | Alibaba | Mar 2026 | Precision editing, frame control | Video clips up to 15s, 1080p |
| Seedance 2.0 | ByteDance | Feb 2026 | Industrial-grade, 2K resolution, 60s duration | Video clips up to 60s, 2K |
Table 1 shows a clear split. GPT-5.4 does not generate video directly. It thinks and plans. The other three create pixels and sound.
Seedance 2.0 currently tops the leaderboard with an Elo score of 1269. That means blind human voters prefer its output over all others.
Think of GPT-5.4 as a director who never touches the camera. It tells other tools what to do. Think of Seedance 2.0 as a one-person film crew. It does camera, sound, and lighting all at once.
Seedance 2.0 leads in raw output specs: 60 seconds at 2K with native audio. Gemini offers SVG animation, a unique lightweight alternative. Wan2.7 excels at frame-level control.
GPT-5.4 does not generate video. It coordinates other tools and software.
Video Generation and Output Quality
Generating video from text is the main event. Each model has different limits on duration, resolution, and quality. Seedance 2.0 pushes the furthest on paper. Wan2.7 focuses on control over raw length.
| Feature | Gemini 3.1 Pro Video | GPT-5.4 | Wan2.7 | Seedance 2.0 |
|---|---|---|---|---|
| Max Duration | Varies (Veo-based) | N/A (coordinates) | 15 seconds | 60 seconds |
| Max Resolution | 720p/1080p (Veo) | N/A | 1080p | 2K |
| Text-to-Video | Yes (Veo engine) | No | Yes | Yes |
| Image-to-Video | Yes | No | Yes (9-grid input) | Yes (9 images) |
| SVG Animation | Yes | No | No | No |
| Native Audio | Yes (Lyria 3) | N/A | Yes | Yes (DB-DiT) |
Table 2 reveals Seedance 2.0 as the spec leader. Its 60-second 2K output with native audio is unmatched. Wan2.7 caps at 15 seconds but offers unique 9-grid image input for richer scene composition.
Gemini 3.1 Pro stands apart with SVG animation. You can generate website-ready animated graphics that stay sharp at any size. File sizes stay small, unlike traditional video formats.
You need a 5-second logo animation for your website. Gemini gives you clean SVG code that loads instantly. Wan2.7 or Seedance 2.0 give you a video file that takes seconds to buffer. Different tools, different jobs.
Wan2.7 offers natural language video editing — change background, lighting, or clothing without regenerating from scratch. Seedance 2.0 provides director-level camera control.
GPT-5.4 can operate your computer to run editing software like CapCut or Premiere Pro automatically.
Control, Editing, and Workflow Integration
Generating video is step one. Editing it is where real work happens. The models differ sharply here. Wan2.7 treats video like a document you can edit with words. GPT-5.4 treats your computer like a tool it can control.
| Capability | Gemini 3.1 Pro | GPT-5.4 | Wan2.7 | Seedance 2.0 |
|---|---|---|---|---|
| Natural Language Edit | Limited | Via computer control | Yes | Yes |
| First/Last Frame Lock | Yes | N/A | Yes | Yes |
| Camera Movement Control | Basic | Via software | Yes | Director-level |
| Computer Automation | No | Yes (OSWorld 75%) | No | No |
| Multi-Shot Consistency | Moderate | Plans it | Good | Excellent |
| Reference Input Limit | 3 images | N/A | 5 videos + voice | 9 images + 3 videos + 3 audio |
Table 3 highlights a major split. Wan2.7 and Seedance 2.0 are built for direct creative control. Seedance 2.0 supports mixed-modality input — up to 9 images, 3 video clips, and 3 audio clips in one prompt.
GPT-5.4 takes a different path. It has native computer use capability, scoring 75% on OSWorld benchmarks — beating the human baseline of 72.4%. It can open CapCut, import your footage, apply transitions, and export the final video.
You want to turn three raw clips into a TikTok edit. With Seedance 2.0, you upload everything and describe the vibe. With GPT-5.4, you say "open CapCut, combine clips one and three, add a slow zoom, export 1080p." It clicks the buttons for you.
Seedance 2.0 and Wan2.7 generate audio in the same pass as video — no separate pipeline needed. Gemini uses Lyria 3 for 30-second music tracks with SynthID watermark.
API costs vary widely. Wan2.7 is cheapest per second. Seedance 2.0 is roughly $0.14–$0.20 per second at standard quality.
Audio, Lip-Sync, and Pricing
Silent videos feel incomplete. Native audio generation changed the game in 2026. Seedance 2.0 and Wan2.7 now generate sound and picture together. Gemini uses a separate but integrated audio engine called Lyria 3.
| Metric | Gemini 3.1 Pro | GPT-5.4 | Wan2.7 | Seedance 2.0 |
|---|---|---|---|---|
| Audio Generation | Lyria 3 (30s tracks) | N/A | Native sync | DB-DiT native sync |
| Lip-Sync Languages | Limited | N/A | Basic | 8+ languages |
| Consumer Price | $19.99/mo (Gemini Advanced) | $20/mo (ChatGPT Plus) | Free tier available | Varies by platform |
| API Input Cost | $2.00/1M tokens | $2.50/1M tokens | $0.10/sec (Together AI) | ~$0.14–0.20/sec |
| Daily Limits | 3–5 video generations | Rate limits apply | 15 free credits | Queue may apply |
Table 4 shows Seedance 2.0 leads in audio with 8+ language lip-sync using its dual-branch diffusion transformer architecture. Wan2.7 offers instruction-based editing where you can change dialogue and sync lip movements automatically.
Gemini 3.1 Pro's Lyria 3 engine produces 30-second professional music tracks. All audio includes SynthID watermark for authenticity. Video generations are limited to 3 per day for Pro users, 5 for Ultra.
Wan2.7 pricing through Together AI is $0.10 per second of generated footage. Seedance 2.0 pricing varies by use case: 28 yuan (~$3.90) per million tokens with video input, 46 yuan (~$6.40) without.
You want to make a 10-second product demo with a voiceover. On Wan2.7 via Together AI, that costs about $1. On Seedance 2.0, roughly $1.50–$2. Both give you video with synced audio in one shot. Pick based on quality needs, not price alone.
