Kuaishou's Kling 4.0 rolls out: director-style 30-second video generation

Kuaishou's video generation model Kling 4.0 officially launched and became fully available on October 15. Its core pitch: shift the AI video workflow from "randomly generating clips" to "directing a film"—creators can tell complete stories, choreograph action, and build visual worlds, with stronger control over timing, motion, and coherence rather than just writing prompts. The company says the new version delivers professional-grade stable motion and audiovisual quality.

Confirmed

Generates up to 30 seconds of video natively in a single pass, making room for long takes, progressive camera moves, and scenes that need time to unfold (@alexverem, multiple posts, m2/m3/m5)
Supports up to 15 reference assets and up to 10 flexible keyframes to guide characters, visual elements, and key narrative beats (m2/m3)
Kling 4.0 is fully available to all users, with a redesigned creation interface (@aziz4ai, m4)
New MCP and CLI access lets users plug Kling into Agent workflows for batch generation and automation (m4)

Why it matters

Native 30-second generation dramatically expands narrative capacity per run, a key step from short-clip demos toward a usable creative tool; multi-reference assets and keyframes markedly improve controllability, matching its "director-style generation" positioning.
MCP/CLI access means Kling can be orchestrated into automated production pipelines, targeting professional and bulk creation scenarios beyond consumer use.
