Seedance 2.0

Capabilities

• Video generation through the current public task endpoint
• Image, reference, duration, or resolution controls when exposed by the live schema
• Current parameters including prompt, resolution, duration

Limitations

• Capabilities and parameter ranges can change; pin and validate the parameter set used in production
• Do not assume support for parameters absent from the live request schema
• Asynchronous jobs require explicit polling, failure, timeout, and safety-status handling

Use cases

• Product prototypes and automated content workflows
• Batch media generation and programmatic creative tooling
• Multi-model applications that need unified authentication, billing, and usage records

Pricing and billing examples

• Input tokens | 6.76470588 | 1M tokens
• Output tokens | 6.76470588 | 1M tokens
