시댄스 2.0과 소라 2: 어떤 AI 비디오 모델이 가장 적합할까요? (2026년 비교) 

선택하는 것 시댄스 2.0 (best for directorial control) and 소라 2 (best for physical realism) is difficult, but accessing them is even harder. Creators are often forced to choose between paying a steep $200/월 에 대한 소라 2 프로 or navigating complex regional accounts for Seedance, effectively doubling their costs and fragmenting their workflow.

At this stage, 시댄스 2.0 is only officially accessible through Jimeng (Dreamina), which puts it out of reach for many creators outside the ByteDance ecosystem. GlobalGPT is working on bringing Seedance 2.0 to its platform. For now, users can rely on advanced alternatives such as 소라 2 그리고 Veo 3.1 ~에 GlobalGPT to produce similar cinematic-quality videos.

The best part? No phone numbers, 지역 잠금 없음, and no waitlists—just instant, 무제한 액세스 to the tools you need.

What Are Seedance 2.0 and Sora 2? (Updated for 2026)

To understand which tool is right for you, you first need to know what they were built to do. They might both make videos, but they have completely different “personalities.”

Seedance 2.0: The “AI Director”

시댄스 2.0 (by ByteDance/Jimeng) is like an obedient actor and special effects artist rolled into one. It cares less about perfect physics and more about following your exact orders.

• It copies your references: The biggest difference is that Seedance can “watch” a video you upload and copy the movement exactly. If you upload a video of yourself dancing, Seedance can make an anime character do that exact same dance.
• It mixes everything: It allows you to use text, images, video, and audio all at the same time to control the result.
• The “TikTok” DNA: Since it comes from the same company as TikTok, it is built for viral content—fast, catchy, and easy to edit, rather than just being a scientific simulation.

Sora 2: The “World Simulator”

Think of OpenAI’s 소라 2 as a brilliant physics genius who is also a cameraman. Its main goal isn’t just to make a pretty video, but to simulate how the real world works.

• It understands physics: Sora 2 knows that if you drop a glass, it shatters. If water hits a rock, it splashes. It tries to make every movement look 100% physically accurate.
• It creates “Long Takes”: It excels at making longer, continuous videos (up to 25 seconds) that feel like a real movie scene filmed by a professional camera.
• The Trade-off: Because it is so focused on realism, it can be stubborn. Sometimes it ignores your specific instructions about 어떻게 a character should move because it’s too busy making the lighting look perfect.

The 2026 Market Context

In 2026, the AI video market has shifted. We are no longer just typing text and hoping for the best.

• From “Prompts” to “Workflows”: The best creators now use a mix of tools. They might use Seedance to plan the shot and Sora to render the final look.
• The “Workflow” Era: This is why platforms like GlobalGPT are becoming essential—they let you use both “The Director” (Seedance) and “The Simulator” (Sora) without switching tabs.

Seedance 2.0 vs Sora 2: Basic Info Comparison

Before we dive into the details, let’s look at the fundamentals of these two models.

Quick Take: If you need multi-asset mixed creation and 2K resolution, go with 시댄스 2.0. If you’re after ultimate physical realism and long-form video storytelling, 소라 2 is your best bet.

8 Core Differences: Seedance 2.0 vs. Sora 2

Difference 1: Output Resolution Comparison

Resolution is one of the key benchmarks for any video generation model.

결론: Seedance 2.0 takes the lead in resolution, offering native 2K output and a wider variety of aspect ratio options. While Sora 2 maxes out at 1080p, it remains top-tier in terms of lighting details and overall visual texture.

Difference 2: Video Duration Comparison

If you’re creating content for large-scale displays, high-definition advertising, or print materials, Seedance 2.0’s 2K resolution offers a clear advantage.

Video length directly impacts a model’s storytelling capabilities. Sora 2 holds a significant advantage in this category:

• 소라 2: Supports 5–25 seconds, a 4x increase over Sora 1’s 6-second limit.
• Seedance 2.0: Supports 4–15 seconds, making it ideal for short-form video and clip production.

For ads or short films that require a complete narrative arc, Sora 2’s 25-second duration gives you more creative breathing room. Meanwhile, Seedance 2.0’s 4–15 second range is better suited for social media clips and product showcases. If you are wondering 소라 2 동영상을 더 길게 만드는 방법, the new updates effectively address this limitation.

Difference 3: Multimodal Input Comparison

This is where Seedance 2.0 shows its most unique strengths.

Seedance 2.0’s quad-modal input system means you can simultaneously provide a face photo, a dance video, and a musical beat, and the model will fuse these elements into one coherent video. This “director-level control” is currently unmatched by other models.

Sora 2’s Cameo feature, on the other hand, allows you to upload your own photo so the AI can “place” you into the generated video. This is essential for creators learning how to use celebrities in Sora 2 or maintain consistent characters.

Difference 4: Physical Realism Comparison

Physical realism is a critical metric for evaluating the quality of video generation models. Sora 2 is the undisputed gold standard in this dimension:

• 소라 2: Offers the highest precision in simulating physical laws like gravity, momentum, collisions, fluids, and light refraction. When you need a basketball to bounce realistically, water to flow naturally, or fabric to flutter in the wind, Sora 2 is the most convincing.
• Seedance 2.0: Shows significant improvement over version 1.5, reaching excellent levels in gravity, momentum, and causality. However, it still lags slightly behind Sora 2 in highly complex physical interaction scenarios.

In real-world tests, Seedance 2.0’s generated scenes—like falling cherry blossoms or swimming koi—are already very realistic and fluid, with natural trajectories and accurate lighting. But for extreme scenarios involving multi-object collisions or fluid simulations, Sora 2’s physics engine still reigns supreme.

Difference 5: Native Audio Comparison

Both models support native audio generation, but they have different focuses.

주요 차이점: Seedance 2.0 supports audio reference input. You can upload a real voice clip or a musical rhythm, and the model will generate the video’s audio based on that reference. This is incredibly valuable for commercial dubbing and maintaining brand audio consistency. Below is an audio demonstration of Seedance.

Below is an audio demonstration of Seedance.

Sora 2 excels in overall audio quality, particularly its ability to generate 배경 음악. It can produce dialogue, sound effects, and a score all in a single inference pass, significantly reducing post-production work.

Difference 6: Multi-Shot Storytelling Comparison

Multi-shot capability determines how well a model can generate long-form, coherent content.

• Seedance 2.0: Features a built-in automatic storyboarding system that can break down a narrative prompt into multiple coherent shots. Character appearance, clothing, and settings remain highly consistent across shots.
• 소라 2: Also supports multi-scene inference with enhanced narrative continuity. It performs at a top-tier level in temporal consistency, ensuring characters don’t “change faces” between shots.

Both perform exceptionally well here, but their approaches differ. Seedance 2.0 relies more on reference materials to ensure consistency (e.g., providing a character reference image), while Sora 2 relies more on the model’s internal understanding to maintain it.

Difference 7: Generation Speed Comparison

Generation speed directly affects workflow efficiency, which is crucial for teams producing content at scale.

Seedance 2.0 has a clear edge in generation speed, thanks to optimizations within ByteDance’s Volcengine computing infrastructure. For workflows requiring rapid iteration and batch production, this speed gap can significantly impact productivity.

Difference 8: API Pricing & Availability Comparison

API pricing and availability are major considerations for developers choosing a platform.

Cost Tip: Sora 2’s official API pricing is relatively high (approx. $5 for a 10-second 1080p video). For budget-sensitive projects, you can access both models via the APIYI (apiyi.com) platform, which offers more flexible billing options suitable for small to medium teams looking to control costs.

The “Director” vs. The “Physicist”

• Choose Seedance 2.0 (The Director) if: You have a specific shot in mind. For example, “I want my character to turn their head 정확히 at second 3,” or “I want this specific camera angle.”
• Choose Sora 2 (The Physicist) if: You want the most realistic texture and lighting possible. For example, “I want a cinematic shot of a rainy street where the reflections look real,” and you don’t mind if the AI improvises the camera movement slightly.

The Verdict on Paper

• 시댄스 2.0 wins on 해상도 (2K is sharper than 1080p) and 속도 (it’s much faster to generate).
• 소라 2 wins on 기간 (25 seconds allows for longer storytelling) and physics quality.
• GlobalGPT is the only way to access both without paying double the price.

Which Model Offers Better Creative Control? (The “Reference” System)

This is the biggest difference between the two. Do you want to describe the scene, or do you want to direct it?

Seedance 2.0’s 4-Modal Input (The “Director” Mode)

Most AI models only let you type text or upload one picture. 시댄스 2.0 changes the game by letting you upload 4 different types of files at once. It’s like giving a human actor a full script, a costume photo, and a dance video to copy.

• 텍스트: Describes the story.
• 이미지: Sets the character’s face or the background style.
• 비디오: Tells the AI 어떻게 to move (e.g., “move exactly like this clip”).
• 오디오: Matches the video rhythm to a specific song or voiceover.

The “Viral Replication” Feature (Copying Camera Movement)

This is Seedance 2.0’s “killer feature” for TikTok and YouTube creators.

• 작동 방식: You can upload a viral video (e.g., a specific camera zoom or a dance trend) and tell Seedance: “Copy this camera movement, but change the character to a cat.”
• 중요한 이유 You don’t need to describe complex camera angles like “dolly zoom” or “pan left.” You just show it a video, and it understands.
• The Benefit: This makes it incredibly fast to produce trending content without being a professional cinematographer.

Sora 2’s “Cameo” Feature

소라 2 approaches control differently. It focuses on keeping the character looking the same, rather than copying specific camera moves.

• 캐릭터 일관성: You can upload a photo of yourself, and Sora 2 will try to keep your face consistent across different scenes.
• The Limitation: It is harder to tell Sora 2 정확히 how to move the camera. It prefers to decide the “best” camera angle for you based on its physics engine.

Is Sora 2 Still the King of Photorealism & Physics?

If Seedance is the “Director,” Sora 2 is the “Scientist.” When it comes to making things look real, Sora 2 is still unbeatable.

The Physics Engine Advantage

Sora 2 doesn’t just paint pixels; it simulates the world.

• Fluids & Water: If you ask for a video of a wave crashing, Sora 2 calculates how the water droplets should scatter. Seedance might make it look “pretty,” but Sora makes it look “correct.”
• Complex Collisions: If a car hits a wall, Sora 2 understands how metal cramples. Seedance might just blur the impact to hide the details.
• 조명: Sora 2’s lighting interacts with objects perfectly, creating reflections and shadows that look like a high-budget movie.

Long-Form Storytelling (25s Continuous Shots)

• The 25-Second Advantage: Sora 2 can generate up to 25 seconds of continuous video. This is huge for storytelling.
• 중요한 이유 You can show a character walking from a dark room into bright sunlight in one smooth shot.
• Seedance’s Limit: Seedance usually works best with shorter clips (5-10 seconds) that are stitched together.

Where Seedance 2.0 Struggles

• The “Uncanny Valley”: Sometimes, Seedance 2.0’s characters might move a bit unnaturally, especially during complex interactions (like hugging or fighting).
• Physics Glitches: Objects might disappear or float if the movement is too fast, whereas Sora 2 keeps them grounded.

Pricing Reality Check: Is Sora 2 Pro Worth the $200 Cost?

Now let’s talk money. This is usually the deal-breaker for most creators.

The Hidden Cost of Sora 2

If you want to use the real Sora 2 (the Pro version with full HD and long videos), it requires a heavy investment.

• The $200 Barrier: To get priority access and fast generation, you often need the highest tier of ChatGPT subscription (Pro), which costs 월 $200.
• The “Pay-Per-Second” Trap: If you use the API, it costs about $0.50 per second for high quality. A single 10-second clip costs $5.00. That adds up remarkably fast during a creative session.

Seedance 2.0’s Economy (The “Loophole” Game)

Seedance is generally cheaper, but it requires navigating a complex system of memberships and temporary loopholes.

• Official Membership (The Entry Gate): As of Feb 2026, accessing advanced features on the 지멩(드리미나) platform typically requires a paid membership costing approx. 69 RMB (~$9.60 USD).
• The “Smart Entry” Trick: New users can often unlock the model via a 1 RMB Trial, utilizing approx. 260 initial bonus points to generate content without a full subscription.
• The “Xiaoyunque” Loophole: Currently, mobile users are exploiting a massive loophole on the 샤오윈크 앱. Reports indicate it is in a “free-to-use” state where generating 15-second clips does not deduct points.
  • 더 캐치: This “free ride” is likely temporary and requires navigating Chinese app stores and phone verification.

The GlobalGPT Advantage ($10.8 for Both)

Why pay $200 for one tool, or hunt for temporary loopholes in foreign apps, when you can pay $10.8 for everything?

• 올인원 액세스: Our Pro Plan ($10.8/mo) 에 액세스할 수 있습니다. 소라 2 프로, 제미니 3 프로, 클로드 4.5, 및 Veo 3.1 (with Seedance 2.0 integration coming soon).
• No “Per Second” Anxiety: You don’t need to count every second like a taxi meter. You just subscribe and create.
• Stability: Instead of relying on a loophole that might close tomorrow, you get stable, guaranteed access to the world’s best models in one interface.

Pro Tip: How to Try for Free? (The “Free Access Hack”)

Before you commit to a subscription, here are some “insider secrets” to test these models without opening your wallet immediately.

1. The “Little Skylark” (Xiao Yunque) Backdoor (Best for Quantity)

• The Secret: Unlike the subscription-heavy Jimeng app, Little Skylark is currently in a “user-growth” phase (often called the “white whoring” period by locals). It is the perfect sandbox for testing prompts.
• The Loot: New users get 3세대 무료 immediately upon login. Plus, you receive 120 free points every day.
• 수학: Generating video costs roughly 8 points per second. This means your daily points allow you to create up to 15 seconds of free video every single day—plenty for testing 2-3 short clips without spending a dime.

2. The “Doubao App” Route (Lowest Barrier)

• 최상의 대상: Casual creators who want the absolute easiest entry point without creating new platform accounts.
• The Offer: A generous 10 free video generations per day (supporting 5s or 10s clips).
• How to Unlock: It requires a one-time “Beta Unlock” process:
  1. Find UID: Open Doubao Settings and copy your User ID (UID).
  2. Join Group: Join the official Feishu (Lark) Beta Group and submit your UID.
  3. 잠깐만요: Approval typically takes 1–2 days. Once approved, Seedance 2.0 appears directly in your app.

3. The “GlobalGPT” Way (Best for Convenience)

• No Hustle: If you hate registering 5 different accounts, verifying phone numbers, and remembering to cancel trials, just use GlobalGPT.
• One Account: One login gets you access to everything without the “points anxiety.”

Developer’s Corner: API Performance & Integration

If you are a coder or building an app, here is what you need to know about the “engine” under the hood.

Generation Speed & Latency

• Seedance 2.0 is Fast: It usually finishes a 5-second video in under 60 seconds. This is great for apps where users hate waiting.
• Sora 2 is Slow: Because it calculates complex physics, it can take 2-5 minutes to generate a single video. It’s better for “offline” rendering, not real-time interaction.

Engineering Workflow (JSON Snippets)

• Seedance Control: You can use specific commands like @image1 as background in your JSON request to control the scene precisely.
• Sora Prompting: Sora relies more on long, descriptive text prompts in the API request body.
