Retire seedance-1-5-pro-251215 from the ByteDance 1.x node docs - #213
Source-of-truth change for the already-open docs PR Comfy-Org/docs#2158 (daxiong/seedance-1-5-pro-retire, head a5d99b03). Mirrors that PR's built-in-nodes/*.mdx edits into the .md files that docs-generation/scripts/sync_to_comfy_docs.py consumes, so the next sync reproduces it instead of reverting it.
Refs PN-1899
Why
BytePlus shuts seedance-1-5-pro-251215 down on 2026-11-11 17:00 UTC+8 with no automatic migration. Workflows saved with it will stop running, and the docs should not keep offering it. The model id is dropped; the surviving options are the 1.0 Pro ids, plus the Seedance 2.5 partner node for audio and longer clips.
What changed (15 files: 3 nodes x en/zh/ja/ko/es)
Node
Changes
ByteDanceTextToVideoNode
model combo loses seedance-1-5-pro-251215; the duration constraint "for 1.5 Pro the minimum is 4 s" is dropped; generate_audio reworded to "Adds an AI-generated audio track. The remaining models ignore this input." and the matching constraint bullet likewise
ByteDanceImageToVideoNode
model combo loses the id; the 1.5-only 4 s minimum is dropped from the duration row; generate_audio reworded as above
ByteDanceFirstLastFrameNode
modeldefault becomes seedance-1-0-pro-250528 and its combo lists that single remaining option; 1.5-only duration/audio wording dropped from the duration row, generate_audio row and the trailing Note:
Every page also gains, directly under the intro:
Note: BytePlus shuts the Seedance 1.5 Pro model down on November 11, 2026, so this node no longer offers it and workflows saved with it stop working. … the Seedance 2.5 partner node instead.
Localized notes are the same sentence in each locale's existing style (**注意：** / **注記:** / **참고:** / **Nota:**), with the per-locale partner-node target. Fingerprint footers are untouched — they hash the node class source, not the md.
One deliberate difference from docs#2158
The note's partner-node link is written as an absolute URL (https://docs.comfy.org[/<locale>]/tutorials/partner-nodes/bytedance/seedance-2-5) instead of the root-relative /tutorials/... used in the .mdx. check_md_links.py resolves a leading / against comfyui_embedded_docs/docs, so a root-relative link fails CI here; Load3D/en.md uses the same absolute form for its cross-page link. Running _normalize_mdx_content() over these files reproduces docs#2158's mdx body byte-for-byte except that link prefix (and one blank line the docs PR's hand edit adds after the frontmatter).
Out of scope, left as-is: the unpublished locales (de, fr, es-siblings it, ru, pt-BR, ar, tr, fa, he, zh-TW) still name the retiring id; docs#2158 does not touch them and translating the note there is a separate call.
Verification
Run from this branch (in-repo branch daxiong/seedance-1-5-pro-retire, under the comfyui-wiki account):
$ python3 .github/scripts/check_md_format.py --changed-only --base origin/main
Checking 15 files changed vs origin/main
Checked 15 files: 0 errors, 0 warnings
$ python3 .github/scripts/check_doc_structure.py --changed-only --base origin/main
0 repaired, 0 defect(s) found
$ python3 .github/scripts/check_md_links.py
All local resource links are valid.
Full-tree check_md_format.py is also clean (Checked 15360 files: 0 errors, 125 warnings, the same 125 pre-existing missing-fingerprint warnings as main), and check_doc_structure.py reports 0 defect(s) tree-wide.
Structural parity vs each node's en.md (heading count, table rows, code fences, tag multiset) holds for all four translations; the only legal difference remains the "Edit on GitHub" self link. No seedance-1-5-pro-251215 string survives in any of the 15 files:
$ grep -rn "seedance-1-5-pro-251215" comfyui_embedded_docs/docs/ByteDance{TextToVideo,ImageToVideo,FirstLastFrame}Node/{en,zh,ja,ko,es}.md
(no matches)
Corresponding docs PR: Comfy-Org/docs#2158 — this source change and that one should land together, otherwise the next sync reverts the docs PR's wording.
BytePlus shuts seedance-1-5-pro-251215 down on 2026-11-11 17:00 UTC+8 with
no automatic migration, so the three ByteDance 1.x built-in node pages stop
naming it and gain a deprecation note instead.
- ByteDanceTextToVideoNode / ByteDanceImageToVideoNode: drop the model id
from the `model` combo list, drop the 1.5-only "minimum duration 4 s" and
"generate_audio ignored for any model except 1.5 Pro" wording, reword
generate_audio as an AI audio track the remaining models ignore.
- ByteDanceFirstLastFrameNode: `model` default becomes
seedance-1-0-pro-250528 (its only remaining option); same wording changes.
- All three: a **Note:** under the intro says the model is retired on
Nov 11, 2026 and points at the surviving 1.0 Pro ids plus the Seedance 2.5
partner node.
Mirrors Comfy-Org/docs#2158 so the next docs sync reproduces it. The note's
partner-node link is written as an absolute https://docs.comfy.org URL
(Load3D-style cross-page precedent) because check_md_links.py resolves a
leading "/" against comfyui_embedded_docs/docs.
Refs PN-1899
The documentation for three ByteDance video nodes is updated in five locales. It describes Seedance 1.5 Pro’s scheduled discontinuation, removes it from the documented model choices, and updates duration and generate_audio descriptions.
The five localized guides document the discontinuation notice and Seedance 2.5 partner node, list seedance-1-0-pro-250528 as the sole model, and update the duration and generate_audio descriptions.
The five localized guides remove Seedance 1.5 Pro from the model choices, add discontinuation and alternative guidance, and update the duration and generate_audio descriptions.

Users receive the retirement date but not the precise migration deadline; adding the cutoff is a small, localized documentation fix.

This node generates a video using a text prompt along with first and last frame images. It takes your description and the two key frames to create a complete video sequence that transitions between them. The node provides various options to control the video's resolution, aspect ratio, duration, and other generation parameters.
**Note:** BytePlus shuts the Seedance 1.5 Pro model down on November 11, 2026, so this node no longer offers it and workflows saved with it stop working. `seedance-1-0-pro-250528` is the only model left on this node. For audio-video and longer clips, use the [Seedance 2.5 partner node](https://docs.comfy.org/tutorials/partner-nodes/bytedance/seedance-2-5).

Add the exact deactivation time.
BytePlus specifies that the model shuts down after 17:00 UTC+8 on November 11, 2026. This notice gives only the date. Add the cutoff time so users can identify the migration deadline. The date is clear, but the time must appear. (docs.byteplus.com)

Este nodo genera un video usando un prompt de texto junto con imágenes del primer y último fotograma. Toma tu descripción y los dos fotogramas clave para crear una secuencia de video completa que realiza una transición entre ellos. El nodo proporciona varias opciones para controlar la resolución, la relación de aspecto, la duración y otros parámetros de generación del video.
**Nota:** BytePlus cerrará el modelo Seedance 1.5 Pro el 11 de noviembre de 2026, así que este nodo ya no lo ofrece y los flujos guardados con ese modelo dejan de funcionar. `seedance-1-0-pro-250528` es el único modelo que queda en este nodo. Para audio y clips más largos, usa el [nodo de la asociación Seedance 2.5](https://docs.comfy.org/es/tutorials/partner-nodes/bytedance/seedance-2-5).

**참고:** BytePlus는 2026년 11월 11일에 Seedance 1.5 Pro 모델을 종료하므로 이 노드에서는 더 이상 선택할 수 없고, 이 모델로 저장한 워크플로는 실행되지 않습니다. 이 노드에 남은 모델은 `seedance-1-0-pro-250528` 하나뿐입니다. 오디오가 포함된 비디오나 더 긴 비디오에는 [Seedance 2.5 파트너 노드](https://docs.comfy.org/ko/tutorials/partner-nodes/bytedance/seedance-2-5)를 사용하세요.
