Introduction
Seedance is ByteDance's flagship family of video generation models on Volcengine. It is designed for cinematic motion, stable subject consistency, and high-quality camera language across both short clips and narrative-style scenes.
With ModelHunter.AI, teams can access the full Seedance lineup through one API key and a unified billing flow. You do not need separate provider accounts, and you can switch across models as your quality, latency, and budget targets change.
Model Family Overview
The Seedance family currently includes four core tiers. Each tier supports both text-to-video and image-to-video workflows with different cost and performance profiles.
| Model | Type | Resolution | Duration | Price/sec Range |
|---|---|---|---|---|
| Seedance 1.5 Pro | T2V + I2V | Up to 1080p | 4-12s (Auto) | $0.012-$0.116 |
| Seedance 1.0 Pro | T2V + I2V | Up to 1080p | 2-12s | $0.024-$0.122 |
| Seedance 1.0 Pro Fast | T2V + I2V | Up to 1080p | 2-12s | $0.010-$0.049 |
| Seedance 1.0 Lite | T2V + I2V | Up to 1080p | 2-12s | $0.017-$0.088 |
All tiers support major aspect ratios including 16:9, 9:16, 1:1, 4:3, 3:4, and 21:9.
Seedance 1.5 Pro
Seedance 1.5 Pro is the top-tier option focused on quality and narrative control. A standout capability is synchronized audio generation, where sound and motion are generated together to preserve timing and scene coherence.
It also supports auto-duration planning: when duration is set to auto, the model chooses an output length based on prompt complexity. This makes it useful for story-like prompts that need different pacing across scenes.
Seedance 1.0 Pro
Seedance 1.0 Pro is a balanced production model for teams that want strong visual quality without always paying for the highest tier.
In practice, it performs well for campaign assets, product teasers, and creator content where consistency matters but throughput also matters. For many teams, this is the most practical default for regular generation.
Seedance 1.0 Pro Fast
Seedance 1.0 Pro Fast is optimized for speed and cost efficiency. It is ideal when teams need to run many experiments, A/B variants, or iterative drafts under tighter latency targets.
If your workflow depends on quick creative loops instead of single-shot premium output, Pro Fast often gives the best cost-to-iteration ratio.
Seedance 1.0 Lite
Seedance 1.0 Lite is the lightweight tier for broad access and predictable spend. It supports the same core workflow types while keeping generation economics easier to manage for startups and high-volume use.
Lite is a good fit for internal tools, prototype validation, educational products, and other scenarios where stable output is needed at lower unit cost.
Key Features
Across the lineup, Seedance provides a practical feature set for real production workflows:
- Text-to-video and image-to-video in the same family
- Multi-shot narrative prompts with better temporal consistency
- Flexible aspect ratios for web, mobile, and social formats
- Resolution options up to 1080p
- Optional audio generation on selected tiers
- Pay-as-you-go usage through a unified API endpoint
Pricing Comparison
When choosing a tier, most teams should compare by expected iteration volume instead of one-off sample quality. A simple way to decide:
- 1.5 Pro: best for premium storytelling output and audio-visual scenes
- 1.0 Pro: best quality-to-cost balance for ongoing production
- 1.0 Pro Fast: best for rapid testing and high-frequency generation
- 1.0 Lite: best for budget-sensitive, high-volume baseline workloads

API Integration
ModelHunter keeps Seedance integration straightforward: one API key, one consistent auth pattern, and a shared response format across models.
Typical integration flow:
- Choose a Seedance model based on your latency and quality target.
- Submit prompt and optional media input through the standard generation endpoint.
- Poll task status or handle webhook callbacks.
- Store output URLs and metadata for downstream product logic.
This makes it easier to migrate between model tiers without rewriting your entire application flow.
Choosing the Right Model
Use this quick framework:
- Choose 1.5 Pro when cinematic quality and audio sync are critical.
- Choose 1.0 Pro when you need strong quality at sustainable production cost.
- Choose 1.0 Pro Fast when iteration speed is the first priority.
- Choose 1.0 Lite when cost control and volume are more important than advanced effects.
Many teams run a hybrid strategy: Fast or Lite for exploration, then Pro or 1.5 Pro for final renders.
Getting Started
Seedance is available now on ModelHunter.AI with transparent pay-as-you-go pricing and no minimum commitment. Start from the model list, run your first generation, and scale up only when output quality meets your product target.
If you are building video features in production, this is one of the fastest ways to ship with the Seedance ecosystem.
