Seedance 2.0 API and ComfyUI Integration Status

AI Video Generation ComfyUI API Seedance

The Seedance 2.0 API has been announced for release in mid–late February. Until it’s actually usable, I’ve organized the current status of the API and its integration with ComfyUI.

Current State of the API Release

The Seedance 2.0 API is not public; only browser (UI) trials are available. There is currently no way for developers to access API endpoints. According to an announcement in the Volcengine developer community, the API release is scheduled for mid to late February 2026 (announcement).

There are four browser-based platforms available: Jimeng (China), Doubao App, the Volcengine Experience Center, and Dreamina (global). They support four input modalities—text, image, video, and audio—and can generate up to 15 seconds with up to nine reference images (Seedance 2.0 product page).

The Volcengine API documentation includes video generation task APIs (create, query, list, cancel/delete) and references Seedance 2.0 support. However, viewing the full specifications requires login, and the endpoints themselves are not yet open (Volcengine API docs).

ComfyUI Support Status

Integration with ComfyUI exists up through 1.5 Pro. On January 21, 2026, the ComfyUI official blog announced support for Seedance 1.5 Pro (blog.comfy.org), providing three workflow templates: text→video, image→video, and First–Last Frame. There has been no announcement for 2.0 yet.

What to Confirm After the API Goes Public

Model ID: The Volcengine Experience Center UI shows doubao-seedance-2.0, but the API documentation’s model list (模型列表) does not yet mention Seedance 2.0, so the official API model ID remains unpublished. A model ID is required to add support to existing ComfyUI nodes.

Endpoint URL: For Seedance 1.x, China (Volcengine: ark.cn-beijing.volces.com) and overseas (BytePlus: ark.ap-southeast.bytepluses.com) endpoints were separate (BytePlus network settings). Version 2.0 may follow the same structure, but this has not been announced.

Pricing: Unannounced. For reference, Seedance 1.x used a token-based price on Volcengine and a subscription plus metered model on BytePlus (Volcengine pricing / BytePlus pricing).

ComfyUI nodes: Given the 1.5 Pro track record, support is plausible (blog.comfy.org), but development and release cannot proceed until the API is publicly available.

ComfyUI Integration Patterns

Pattern A: Wait for the official ComfyUI node

There is an official support track record for 1.5 Pro (blog.comfy.org), so a 2.0-compatible node is likely. Once announced, you can just update the node without building your own API integration. The timeline depends on the ComfyUI team.

Pattern B: FloyoAI/ComfyUI-Seed-API + BytePlus

A community node that supports the BytePlus API (global) (GitHub, last commit: 2026-01-16). It currently supports models such as seedance-1-5-pro-251215. It may work for Seedance 2.0 by adding the model ID to the config. Practically, file an issue to the developer or fork and edit it directly.

Pattern C: kookliu/ComfyUI-Custom-Nodes + Volcengine

A node that supports both Volcengine and BytePlus (GitHub, last commit: 2025-09-25). It may be stale, so it’s lower priority than B. Still an option if you use the China-facing API.

Pattern D: Build your own node

Once the endpoint and model ID are finalized, you can build your own integration using a Python script node or a custom ComfyUI node. For Seedance 1.x, authentication used a Bearer Token and the request structure can be confirmed in the Volcengine API docs (Volcengine API docs).

Minimal Steps After the API Goes Public

  1. Confirm the model ID — Check the official model ID for Seedance 2.0 in Volcengine’s model list (模型列表).

  2. Obtain an API key — Issue API keys from the BytePlus (overseas) or Volcengine (China) console. Since we don’t know which will go first, having both accounts ready makes it easier to move quickly.

  3. Install FloyoAI/ComfyUI-Seed-API — Use ComfyUI Manager to install FloyoAI/ComfyUI-Seed-API and check whether the Seedance 2.0 model ID has been added. If not, add it directly to the config or request it via an issue.

  4. Run a test generation — Use a simple text→video workflow to generate one clip and verify it works.

Notes

  • Regional restrictions: In Seedance 1.x, Volcengine served China while BytePlus served overseas (BytePlus network settings). Version 2.0 may keep the same split, but it hasn’t been announced. From Japan, prioritizing BytePlus may be lower risk.

  • Dreamina does not provide an API: The global version of Dreamina is browser-only and cannot be used for ComfyUI integration (Seedance 2.0 product page). For API integration you will need Volcengine or BytePlus.

  • No way to pre-estimate pricing: Since pricing is unannounced, you cannot estimate costs before building automated workflows. Use the 1.x price tables (Volcengine / BytePlus) as a ceiling so comparison is easier once pricing is published.

  • Community node update cadence: The kookliu branch hasn’t been updated since September 2025 (GitHub). Practically, start with the FloyoAI branch.

Waiting for a mid–late February release. Once the model ID, endpoint URL, and pricing are published, start either by updating the official node (Pattern A) or by adding the model ID to FloyoAI/ComfyUI-Seed-API (Pattern B).
