Kling4 — Multi-Model AI Video Studio Featuring Kling 4.0

What is Kling4?

Kling4 (kling4.me) is an independent, third-party AI video studio — the site states plainly that it is "not made by Kuaishou or Kling AI." Its core product is a multi-model picker that hosts 18 video generation models from 7 brands in one interface, letting users switch between engines without managing separate accounts. The studio leans its identity on Kling 4.0, Kuaishou's successor to Kling 3.0, and dedicates substantial page space to explaining that model's specification.

The important nuance, which the site itself discloses: the studio currently runs the Kling 3 series (Kling V3 Turbo is preselected), and Kling 4.0 will be added "when third-party API access opens" — no date promised. Sample clips on the page come from the Kling 3 series, Hailuo, Seedance, and HappyHorse, and the site states explicitly that "none of them is Kling 4.0 output."

How Kling4 Works

The workflow is three steps. First, pick a model from the picker. Second, enter a text prompt or upload an image and set the aspect ratio, resolution, and duration. Third, generate, review, adjust, and download — downloads require the Basic plan or higher.

Generation is metered in studio credits: 90 credits for a 720p 5-second clip and 180 credits for 10 seconds, with costs varying by model and resolution. New accounts receive free credits, and the Kling V3 Turbo and Kling 2.6 models run free, so a new user can produce first clips without paying.

Main Features

• 18-model picker — video engines from 7 brands in one studio, switchable per generation.
• Kling 3-series support today — V3 Turbo preselected, with V3 Turbo 15-second clips and 1080p on the Basic tier.
• Documented Kling 4.0 roadmap — per the site's summary of Kuaishou's release notes: 3–30 second takes, 720p/1080p/4K (10-bit HDR "coming soon"), 21:9 ultrawide, up to 10 keyframes, up to 15 references per generation (10 images, 5 videos, up to 7 subject elements, one voice sample), prompts up to 8,000 tokens, and edits across up to 5 input clips.
• Multilingual audio (model-level) — two-channel stereo, improved lip sync, and speech in English, Spanish, Portuguese, French, German, Chinese, Japanese, Korean, Indonesian, and more, on supporting models.
• Free tier — free starting credits plus free running of V3 Turbo and Kling 2.6.
• Image-to-video and text-to-video — prompts or image uploads drive generation across supported models.

Pricing

Kling4 uses a credit system with tiered plans, but exact dollar amounts are not listed on the reviewed homepage — the page points to a separate /pricing route. What is stated: new accounts get free credits; the Free tier runs Kling V3 Turbo and Kling 2.6 at no cost; the Basic plan unlocks downloads, Kling 3.0, 1080p output, and 15-second V3 Turbo clips; and Pro/Business tiers are required for 4K output. At the published credit rates, a single 720p 5-second generation consumes 90 credits, so credit value depends on the per-plan credit allocations, which were not visible on the reviewed page.

Common Use Cases

• Model comparison — testing the same prompt across 18 engines from different brands without multiple subscriptions.
• Short-form social clips — fitness demo reels using keyframes, travel vlogger cold opens in 21:9, product brand videos with consistent characters.
• Multilingual content — lessons and marketing clips with in-video text and speech across ten-plus languages on supporting models.
• Photo animation — turning family or pet photos into short clips via image-to-video.

Limitations

The gap between name and product is the central caveat: despite the domain and branding, Kling 4.0 is not yet available in the studio, and the site is honest about it. The 10-bit HDR mode and the 2-minute video extension are also "coming soon," and the Flash tier is capped at 20 seconds and 720p. Downloads — the point of generation for most creators — require a paid Basic plan or higher, and no refund policy is mentioned on the reviewed page. As a third-party wrapper, Kling4 depends on upstream vendors' API availability, and its spec descriptions of Kling 4.0 are summaries of Kuaishou's release notes rather than independent benchmarks; the site itself notes Kling has published no numeric comparison against Kling 3.0.

Summary

Kling4 is a genuinely useful aggregation play — one picker, 18 models, credit accounting, and a free starting tier — wrapped in branding that runs ahead of its catalog. For creators who want to comparison-shop video engines or burn free credits on V3 Turbo clips, it works today. Buyers should treat it as a Kling 3-era multi-model studio with a documented Kling 4.0 wait, verify dollar pricing on its /pricing page before committing, and remember that the studio is unaffiliated with Kuaishou despite the name.
