I always like @Kling_ai when it's come to visual fidelity and realism motion and now they are releasing new SOTA model soon. Leaked settings reveal Kling is prepping 4.0 Preview and 4.0 Flash Preview. Here is every technical spec, limit, and workflow restriction spotted in the early setup: Video Generation & Models: • Kling 4.0: 3–30s runs across Omni-reference & keyframe workflows. Supports 720p/1080p, with keyframe mode allowing up to 10 keyframes. • Long Video (Experimental 4.0): 3–120s generation (720p & 1080p only; 2K/4K are excluded). Supports forward and backward video extensions. • Kling 4.0 Flash: 3–20s runs in Omni-ref, currently locked to 720p. • Omni: Appears purely as a workflow inside 4.0, not a separate standalone model. • Extensions: 3–60s extension steps, with source clips capped at 60s. Multimodal Reference Limits: • Standard Mode: Up to 15 total combined references (max 10 images, 5 videos, 7 Elements). • Uploaded Reference Video Durations: 2–30s on 4.0, and 2–20s on Flash (these caps apply to input reference clips, not generation length). • Voice Refs: Up to 3 indicated for 4.0; zero listed for Flash (doesn't necessarily rule out Flash generating audio, just no voice inputs yet). • Long Video Mode Restrictions: Hard capped at 5 image/Element references total----no video or voice inputs permitted. Image 4.0 & Architecture: • Testing Default & Series modes, generating 1–9 images per batch. • Resolution toggles show 2K, 4K, and 8K (native 8K output remains unconfirmed). • Early flags point to 2D/3D plugin hooks, experimental audio tools, and VIP rollout tiers. API & Billing: • Full 4.0 seems slated for separate API packages and dedicated video-input billing. Flash may be lumped into existing 3.x tier packages. No pricing finalized yet. @techhalla @NEXUS_TO_NOVA @IamEmily2050 📷 Devmode/Mars
