Pricing Outlook
Confirmed Seedance 2.5 API rates are not available through RSW AI Studio yet. Historical Seedance 2.0 rates can help teams think about budget ranges, but they are not an offer for Seedance 2.5 API service. Confirmed rates and credit conversion will be published only after official public API access and RSW support are confirmed, including on the pricing page after confirmation.
Build While You Wait
- Prepare prompts in the preview workspace. The Seedance 2.5 page has a parameter preview and capability examples for planning, not live Seedance 2.5 generation.
- Ship against 2.0 now. Seedance 2.0 generation is live today with free credits. Keep your integration flexible until official Seedance 2.5 API fields and access rules are public.
- Track the rollout. The release-date tracker covers platform-by-platform availability without claiming RSW API access before it is confirmed.
Seedance 2.5 API FAQ
When does the Seedance 2.5 API launch?
Seedance 2.5 API access through RSW AI Studio will remain unavailable before the official Volcano Engine or BytePlus public API becomes available. After official public access exists, we will evaluate support and update this page with confirmed availability.
How much does the Seedance 2.5 API cost?
Confirmed Seedance 2.5 API pricing is not available here yet. Any price on this page is an outlook or historical reference, not an offer for live Seedance 2.5 API service.
What parameters will a request support?
Based on public capability announcements, likely parameters include prompt text, generation mode, duration, aspect ratio, resolution, reference inputs, and audio options. Exact field names, limits, and request rules must wait for official public API documentation.
Can I test Seedance before API access opens?
You can test Seedance 2.0 generation today. Seedance 2.5 generation and Seedance 2.5 API testing are not available through RSW AI Studio yet; the Seedance 2.5 workspace is a preview with a launch-status notification option.
Do I need my own ByteDance or BytePlus account?
For official Seedance 2.5 API access before third-party support is confirmed, follow the official Volcano Engine or BytePlus channels. RSW AI Studio does not offer a workaround, bypass, or unofficial Seedance 2.5 API route.
