Is Kling 4.0 available now?
No, the full Kling 4.0 model is not available on October 2, 2026. Only Kling 4.0 Flash is live, and only for some accounts. Kling's Kling 4.0 feature page says "Kling 4.0 Flash is available first to a limited group of creators" and tells users to sign in to Kling Creator Studio to check whether the account has Kling 4.0 Flash.
Kling AI's post on X names the group: "Kling 4.0 is coming this October. Kling 4.0 Flash is live now for Ultra Yearly subscribers." TechTimes reported on September 30, 2026 that Kling 4.0 Flash opened to Ultra Yearly subscribers in a closed beta on September 28. Kling's blog and feature page do not name a plan, so treat the Ultra Yearly requirement as stated on X and not yet written into Kling's plan documentation.
What is the difference between Kling 4.0 and Kling 4.0 Flash?

What features does Kling 4.0 have?
Kling AI has announced 7 Kling 4.0 features for the full model. These features are officially announced and not yet available to the public.
- Clip length: Kling 4.0 supports native video generation from 3 to 30 seconds.
- Keyframes: Kling 4.0 supports up to 10 flexible keyframes inside one generation.
- References: Kling 4.0 supports up to 15 combined reference assets in a single generation, including up to 10 images, up to 5 videos with a combined duration of up to 30 seconds, and up to 7 subjects.
- Resolution: Kling 4.0 supports 4K output and 21:9 ultrawide video, next to the 16:9, 1:1 and 9:16 formats.
- Audio: Kling 4.0 supports two-channel stereo audio, improved lip-sync accuracy and voice references for a character's vocal identity.
- Prompts: Kling 4.0 supports prompts up to 8,000 tokens.
- Text: Kling 4.0 improves multilingual text, logo and emoji generation during camera movement and scene transitions.
Kling's feature page counts dialogue in 9 languages. Kling's guide names Chinese, English, Japanese, Korean, Spanish, Portuguese, German, French and Hindi.
One caveat applies to resolution. Kling's guide says "Support for 10-bit HDR at 1080p and 4K is coming soon," so HDR output has no confirmed date, even for launch day.
Which generation modes does Kling 4.0 support?
Kling 4.0 supports 3 generation modes: text-to-video, image-to-video and video editing. Kling AI describes 2 more workflows around those modes.
- Video editing: the full model accepts up to 5 video inputs in an editing task, including 1 primary video, with a combined duration of up to 30 seconds.
- Video reference: Kling 4.0 uses an existing video as a reference for pacing, shot composition and camera movement.
- Video extension: Kling AI says video extension lengthens a video forward or backward across multiple passes, up to 2 minutes (120 seconds) in total. Kling's developer page marks video extension as coming soon.
Kling AI is shipping a redesigned creation page with the model. Kling's guide lists unified multimodal input, Grid and List views, timeline-based editing, and a Canvas and Agent experience.
