What is this site?
Kling 4 (kling4.io) is an independent third-party site that tracks Kuaishou Kling 4.0 specs and release timing while offering browser text- and image-to-video. Kling 4.0 was announced on September 28, 2026, with a full launch planned for October. Until a third-party API opens, the site uses the newest callable Kling engine and labels each clip with the model used. It is unaffiliated with Kuaishou or official Kling AI, and fits users who want 4.0 updates plus prompt practice and sample clips now.
Key features
- Text-to-video and image-to-video: submit a prompt or reference image in the browser and download an MP4
- Native audio can be generated with the picture and toggled per shot
- Every finished clip is labeled with the model that made it, so “can generate” is not mistaken for “already 4.0”
- Summarizes public Kling 4.0 specs, release timing, and comparisons versus Kling 3.0
- Free starter credits and check-in bonuses; monthly plans or one-time packs; failed renders refund credits
Common use cases
- Creators refine prompts and shot structure on current engines before the 4.0 API opens
- Content teams track capability changes from Kling 3.0 to 4.0, such as length, keyframes, and reference counts
- Marketers produce shareable sample clips first, then decide whether to scale generation
- Users who need an independent summary of 4.0 specs and launch status rather than marketing slogans alone
Who is it for?
- Creators who follow Kling 4.0 release and specs while generating short clips today
- Individuals and small teams practicing text- or image-to-video under a third-party credit system
- Users who must keep “tracked 4.0” separate from “engine available right now”
- Poor fit: anyone who must use an official app account, or who treats a third-party site as the official channel
- Also a poor fit: anyone who needs true Kling 4.0 or Flash output today (not possible before the API opens)
How does it compare?
Check these points instead of invented leaderboards:
- Role: this site combines Kling 4.0 tracking with generation; if you only want Flash volume ASAP, the product focus differs
- Availability: 4.0 and Flash wait on a third-party API; current output uses the newest open engine and labels the model
- Official source: news and the official app still belong on kling.ai / klingai.com; this site states no affiliation
- Commercial use: site terms allow personal and commercial use subject to the model provider's policies and non-infringement; read the terms for details
FAQ
Q: Is kling4.io the official Kling AI website?
A: No. It is an independent third-party platform and is not affiliated with, endorsed by, or operated by Kuaishou or Kling AI.
Q: Can I generate real Kling 4.0 videos here now?
A: Not yet. The site states the 4.0 third-party API is not open; generation uses the newest available Kling engine and labels the actual model.
Q: Are Kling 4, Kling 4.0, and Kling V4 the same?
A: Per the site, the official name is Kling 4.0; those labels usually mean the same full model. Flash is the lighter, speed-and-cost-oriented version in the same generation.
Q: Is it free, and is there a separate app?
A: Google sign-in grants free credits with check-in bonuses; then monthly plans or one-time packs are available. The site runs in the browser with no site-specific app install; the official Kling app is a separate product and credits do not transfer.
