docs(kling): add the Kling 4.0 partner node page and pricing - #2130
Adds the documentation page for Kling 4.0, the partner-node video model added in Comfy-Org/ComfyUI#17364, and its pricing rows.
What is covered
New page tutorials/partner-nodes/kling/kling-4-0.mdx (en, zh, ja, ko, es), covering the four nodes and the four templates added in Comfy-Org/workflow_templates#1378:
Kling 4.0 Text to Video (api_kling4_t2v)
Kling 4.0 Image to Video (api_kling4_i2v), up to 10 keyframes across first_frame, middle_frames, last_frame
Kling 4.0 Reference to Video (api_kling4_r2v), up to 10 reference images and 5 reference clips, adaptive aspect ratio
Kling 4.0 Video Edit (api_kling4_video_edit), up to 4 additional reference clips and 10 reference images, output keeps the input length
Node inputs, option values, and limit checks come from the node schemas in comfy_api_nodes/nodes_kling.py; the workflow descriptions come from the templates. Model capabilities (30 second generation, 10 keyframes, 15 reference assets, stereo audio) are from Kling AI's own Kling 4.0 announcement.
Pricing
pricing.mdx gains a kling-4.0 block in the Kling video section, with the per-second credits derived from the node price badges: 47.37/sec at 720p and 70.91/sec at 1080p for generation, plus the reference-video range and the per-second-of-input billing for Video Edit. The exception sentence in the section intro now lists Kling 4.0 Edit Video, which follows the input clip's length instead of duration.
Notes
The Cloud card is commented out on each workflow: the four templates landed in workflow_templates today, and Comfy Cloud availability was not confirmed, so only the Download card is shown for now.
Navigation entries are added at the front of the Kling group in all five language blocks of docs.json.
All preview and input assets return 200 on raw.githubusercontent.com (checked before embedding).

Merge Risk: Low · previous review d5bf3
The pricing pages may still cause users to calculate incorrect charges for connected-reference workflows; clarify the exception as a low-risk follow-up.

Review comments at @es/tutorials/partner-nodes/kling/kling-4-0.mdx:
- Line 3: Shorten the description in the Kling 4.0 tutorial front matter to 160
characters or fewer while retaining all listed workflow capabilities:
text-to-video, ten-keyframe animation, reference shots, and prompt-based edits.
- Line 146: Update the limits in the Kling 4.0 parameter table to use Spanish
thousands separators: format the prompt limit as 26.000 caracteres and the pixel
limit as 8.294.400 px, preserving their existing meanings and units.
Review comments at @ja/tutorials/partner-nodes/kling/kling-4-0.mdx:
- Line 2: Update the title metadata so it begins with “Kling 4.0” instead of
“ComfyUI,” while retaining the Japanese description of the workflow
capabilities.
Review comments at @ko/tutorials/partner-nodes/kling/kling-4-0.mdx:
- Line 2: Update the title in the page frontmatter to start with “Kling 4.0,”
while retaining the existing workflow capabilities in the title.
Review comments at @tutorials/partner-nodes/kling/kling-4-0.mdx:
- Line 136: Update the prompt description row in the Kling 4.0 tutorial to
distinguish Reference to Video’s `@ImageN` and `@VideoN` references from
connected keyframes, which are added automatically as `first_frame` and
`last_frame`. Apply the same clarification to the localized copies.
Review comments at @zh/tutorials/partner-nodes/kling/kling-4-0.mdx:
- Line 2: Update the frontmatter title in this tutorial so it begins with “Kling
4.0” and retains the existing workflow capabilities in Chinese.

workflow_templates Comfy-Org#1378, with credits per second from the node price badges.
Align docs with ComfyUI Kling4EditVideoNode price badge:

Applies to flat rate and reference-video range upper bound in all five locales.

- Line 689: Update the Video edit pricing formula in all five locales to account
for the total input duration sent by Kling4EditVideoNode, including video_1 and
reference videos; with references, use the documented rate multiplied by
duration plus the greater of total input duration and duration. Preserve the
