Kling 4.0 on Higgsfield: What's New, How to Use It and What It Costs

Kling’s newest video model arrived on Higgsfield on October 21, 2026. It’s a big step up from Kling 3.0 for ad work: longer takes, more control over what happens in the shot, and the ability to fix a finished clip instead of regenerating it. Here’s what’s new, how to use it and what it costs, based on Higgsfield’s changelog and official blog.

What’s new in Kling 4.0

According to Kling, as summarized by Higgsfield:

• Steadier motion: more stable in fast scenes like fights, sports and character interaction, with stronger camera work.
• Up to 10 keyframes across the video, instead of first and last frame only.
• Up to 15 references: images (up to 10), videos (up to 5), a voice reference and Elements. Creative Recreation reuses the pace, composition and motion of an existing video.
• Video editing: swap a character, product, background, camera angle or style in a finished clip.
• Output: 3 to 30 seconds, 720p or 1080p, aspect ratios from 21:9 to 9:16, stereo sound and voiceover in 9 languages, including English, Spanish, Portuguese, German, French, Hindi, Japanese, Korean and Chinese.
• Long prompts: up to 8,000 tokens, so you can describe action and camera moves between keyframes in detail.

Kling 4.0 vs Kling 3.0

The biggest practical gains for ads: 30-second takes and editing a clip you already like.

Kling 3.0 is still a solid choice for 15-second social clips. Higgsfield’s Plus plan has included time-limited unlimited Kling 3.0, which makes it the cheaper option for quick tests. Pick Kling 4.0 when you need longer takes, precise beats via keyframes, or a fix to an existing clip.

How to use Kling 4.0 on Higgsfield

1. Go to Video → Create Video.
2. In Model, select Kling 4.0.
3. Choose a mode: References, Frames or Edit video.
4. Add inputs: reference images or videos; first, last or extra keyframes; or the clip you want to edit (up to 5 clips, 1 main, 30 seconds combined).
5. Write the prompt step by step, including action and camera movement between keyframes.
6. Set duration (3–30 seconds), resolution (720p or 1080p) and aspect ratio (Auto, 21:9, 16:9, 9:16 or 1:1).
7. Check the credit cost on the Generate button, then generate.

Higgsfield’s tip: when a result is close, change one thing at a time (prompt, reference or duration) so you can see what made the difference.

How much Kling 4.0 costs on Higgsfield

Kling 4.0 runs on credits. Higgsfield’s published figures:

That works out to 5 credits per second at 720p and 7.5 at 1080p. Higgsfield also announced a limited-time launch discount from October 21, 2026; the exact price is always shown on the Generate button. For how many credits each plan includes, see our Higgsfield pricing guide.

Try Kling 4.0 on Higgsfield New users may get a personal discount of up to 50%, valid for 3 hours after signing up.

Kling 4.0 Flash: the cheaper version for tests

On November 4, 2026, Higgsfield added Kling 4.0 Flash, a lighter Kling 4.0 for quick tests and short videos. It has the same modes (References, Frames and Edit video) with fewer controls:

Higgsfield’s advice: use Flash to test ideas, then switch to Kling 4.0 for final versions with keyframes and 1080p. The exact Flash price appears on the Generate button (higgsfield.ai/ai/video?model=kling_4_0_flash).

Higgsfield or Kling directly?

Higgsfield gives you Kling 4.0 alongside Seedance, Nano Banana and its own tools on one credit balance. Going direct to Kling makes sense only if Kling is the one model you use. We compare the options in Higgsfield alternatives and Higgsfield vs Runway.
