What Kling 4.0 is
On 30 September 2026, Kling AI published Introducing Kling 4.0, describing a next-generation video model with updates across dynamic motion, native 30-second generation, Omni Reference, and multiple keyframes. Kuaishou’s 16 October 2026 release says Kling 4.0 officially launched on 15 October 2026, with upgrades centered on realism, control, and professional quality.
Those official posts said Kling 4.0 capabilities would soon be available to enterprise customers and developers through API access. fal now lists active hosted endpoints under kling/v4, including text-to-video, image-to-video, reference-to-video, and video-to-video/edit. This page covers the video root. bnrouter does not invent a gateway model id or a price for this page.

Where developers can use it
Kling AI lists these official surfaces first. bnrouter is an optional OpenAI-compatible gateway in front of connected upstream accounts.
- Kling AI website and creation tools, as described in Kling’s 30 September 2026 post
- Kling MCP and CLI, as named in Kuaishou’s 16 October 2026 release
- Hosted fal kling/v4 text-to-video, image-to-video, reference-to-video, and video-to-video/edit endpoints
- bnrouter, if the operator has connected an upstream that serves this model. The plaza may still show coming soon — confirm the id in the console or GET /v1/models.
How to call it through bnrouter
bnrouter is an OpenAI-compatible AI API gateway. Create an API key in the console, then send requests to the gateway base URL. Chat completions may not be the right request shape for image or video generation — see the Image & video API docs for the images format this site already documents. This repository does not yet record a gateway model id — copy the id shown in the console (or from GET /v1/models) into the model field. The plaza listing may still show coming soon.
curl https://www.bnrouter.com/v1/chat/completions \
-H "Authorization: Bearer $YOUR_API_KEY" \
-H "Content-Type: application/json" \

"model": "YOUR_MODEL_ID",
"messages": [{"role": "user", "content": "Hello!"}]
}'from openai import OpenAI

base_url="https://www.bnrouter.com/v1",
)
resp = client.chat.completions.create(
model="YOUR_MODEL_ID",
messages=[{"role": "user", "content": "Hello!"}],
)
print(resp.choices[0].message.content)Replace YOUR_API_KEY and YOUR_MODEL_ID with values from the console. Do not assume a model id that is not listed there.
