Official · Kling AI

Official · Kling AI
04
4K HDR + stereo audio
Output up to 4K with 10-bit HDR, dual-channel stereo audio, and sharper lip sync — closer to a finished professional cut.

More FAQ

What is the difference between Kling 4.0 and Kling 4.0 Flash?: Flash is the fast, cost-efficient tier for high-volume iteration. The full Kling 4.0 model targets maximum quality — longer native clips, richer references, and 4K HDR output. Only Flash is accessible today, and only on Kling's Ultra Yearly plan.
Will Kling 4.0 have API access?: Kuaishou has not published a Kling 4.0 API model ID or price row as of September 28, 2026. Kling 3.0 is available via API today. Reeldo will add 4.0 to the same /api/v1 flow once providers ship it.
How much will Kling 4.0 cost?: No official pricing yet. Kling has not announced credit changes for 4.0. On Reeldo, Kling 3.0 runs from 8 credits/sec (Standard, sound off) to 36 credits/sec (4K). We will publish 4.0 rates here before enabling generation.
Is Reeldo the official Kling website?: No. Reeldo AI is an independent platform that integrates models such as Kling through third-party APIs. We are not affiliated with or endorsed by Kuaishou. Official access is at klingai.com.
How do I get early access to Kling 4.0 Flash?: Flash is currently limited to Kling Ultra Yearly subscribers on klingai.com. Reeldo cannot grant Flash access until the API tier is published. Use Kling 3.0 on Reeldo for immediate generation, or subscribe on Kling's site for their native Flash preview.

Kling 4.0 is coming to Reeldo

We will enable Kling 4.0 and Flash with transparent credits the day Kie/Fal ship the API. Until then, Kling 3.0 is live — Standard, Pro, and 4K with native Sound-On.
