Kling Video O1. Kling quality at a workhorse price.
Kuaishou's O1 generates cinematic 5 or 10 second clips with native audio, keyframes at both ends, and negative prompts, at about 11 cents per second.
- 5 to 10 second clips
- 3 aspect ratios
- Native audio
- First and last frame control
Kling Video O1 is the volume pick in the Kling family. It takes text or an image, returns a 5 or 10 second 720p clip with native audio, and accepts a first and last keyframe so shots land where you planned. Negative prompts let you fence off what you do not want in frame, which matters when a pipeline is generating unattended.
At roughly 11 cents per second it undercuts the premium models by enough to change how you work: run three takes and keep the best one, or let a daily pipeline generate on schedule without the bill spiking. On Treza it shares the canvas with Kling 3.0 Pro, so the common pattern is O1 for the everyday shots and 3.0 Pro when the brief is fast human action.
Fixed 5 or 10 second clips
Two clean duration options that map directly to short-form beats: a hook or a full moment, priced predictably.
Native audio
Sound generated with the picture, so a pipeline can go from prompt to publishable clip without a separate audio pass.
Negative prompts
Say what must not appear. Useful insurance for scheduled pipelines that generate without a human reviewing every prompt.
Keyframes at both ends
First and last frame control in landscape, portrait, and square, so storyboarded shots hold their composition.
What to make with Kling Video O1
Real prompts, and what comes back. Every one runs in Treza chat or as a node on the canvas.
“A street vendor flips noodles in a wok, steam and neon, 10 seconds”
A cinematic food beat with native sound.
“A cat leaps between rooftops at dawn, 5 seconds, square”
A short loopable clip for social.
“A ferry crosses a harbor at dusk, city lights coming on, negative: people”
A controlled scene with the exclusion honored.
“First frame: sealed package. Last frame: product revealed in hand”
An unboxing beat with pinned start and end.
“Rain streaks a bus window, city blurred beyond, 9:16”
A moody vertical loop for Shorts and Reels.
“A barista pours latte art, cafe chatter behind, 10 seconds”
An everyday scene with sound, ready to caption.
Kling Video O1 is one node on a canvas
Chain it with language, image, and video models, then publish the whole pipeline as an API.
- Step 01
Draft the brief
A language model node expands a one-line idea into a detailed, on-brand prompt before it ever reaches the model.
- Step 02
Generate with Kling Video O1
Run variants in parallel, compare against other models on the same prompt, and keep every result in run history.
- Step 03
Publish it as an API
The pipeline becomes a versioned endpoint. Your product calls it with the typed /invoke API or any OpenAI SDK.
Kling Video O1, answered
How is Kling Video O1 different from Kling 3.0 Pro?
3.0 Pro is the flagship for fast human motion, longer duration options, and premium action work. O1 trades that range for a lower per-second price with native audio and keyframe control intact. For scheduled pipelines and everyday shots, O1 is usually the economical default; reach for 3.0 Pro when bodies in motion carry the clip.
What are negative prompts good for?
Keeping things out of frame: brands you cannot show, crowds you do not want, styles to avoid. In automated pipelines where a language model writes the prompts, a standing negative prompt is a guardrail that travels with every run.
Can I use Kling Video O1 in an automated pipeline?
Yes. It works like every Treza model: pick it in chat, wire it on the canvas, publish the pipeline as a versioned API endpoint. Its price point makes it a natural fit for daily scheduled content.
How much does Kling Video O1 cost on Treza?
Treza uses prepaid credits with no subscription. Each clip is charged at Kling Video O1's rate from your balance, and only successful generations are charged. Credit packs start at $5 and never expire.
Can I call Kling Video O1 through an API?
Yes. Build a pipeline that uses Kling Video O1 and publish it as a versioned HTTP endpoint. Call the typed /invoke API from your product, or point any OpenAI SDK at the OpenAI-compatible endpoint. If a better model ships later, swap it on the node without changing the API your product calls.
