Kling 4.0 just got revealed and it hits 30 seconds 🎬

Good morning. Kling pulled the curtain back on 4.0, its next video model, and a Flash preview is already in some creators’ hands. Runway keeps stacking the best outside image models into its platform. And a totally fake AI guy in a fedora is pulling tens of millions of views playing a street celebrity. Would you follow an AI character if it was genuinely entertaining? Hit reply and let me know! Let’s get into it.

Kling, one of the top AI video tools out there, revealed Kling 4.0, its next-gen model, and it’s a real jump. The headline number is length, it can generate up to 30-second clips, a big leap when most tools still tap out around 5 to 10. It also pushes up to 4K, handles up to 10 keyframes for controlling the action, and takes massive detailed prompts.

Alongside it there’s Kling 4.0 Flash, a lighter, faster version built for cranking out clips quickly and cheaply. The split is the usual one, Flash for fast everyday generating, full 4.0 for your highest-quality hero shots. Flash is the one already in early access, though right now it’s limited to Kling’s top-tier annual subscribers.

The full 4.0 isn’t out for everyone yet, it’s set to launch more widely in late October, and the Flash preview is gated behind the priciest plan for now. So this is more “get ready” than “go make something tonight.” But longer, sharper, more controllable clips are exactly what the ceiling has been on AI video, so when this fully drops it’s worth testing.

Runway has quietly turned itself into a one-stop shop for AI image models, not just its own. Over the last couple months it’s been plugging the best outside image generators straight into its platform, so you can call them inside one workflow instead of juggling five separate tools and logins.

The recent haul shows the pace. Ideogram, the model everyone loves for actually getting text right in images, got added, first 4.0 and now the newer 4.5. On top of that, Seedance’s sibling Seedream 5.0 Flash landed for fast high-res images from text or references, plus an automatic background remover. It’s Runway betting that the winning move isn’t having the single best model, it’s being the place where you can use all of them.

For creators, the takeaway is convenience is becoming its own feature. If you’re tired of bouncing between Ideogram for text, something else for photorealism, and a third thing for editing, a hub that keeps the top models under one roof genuinely saves time. Worth a look if you want your whole image workflow in one tab, just note the good stuff sits on the paid plans.

Meet Rostam Luti, a suave, mustached character in a black fedora and a gold nameplate chain who struts around posing with adoring crowds like the most confident man alive. He’s not real, the whole account is AI-generated, and it’s working, 254,000 followers off just 39 posts, with one clip sitting at over 32 million views.

It works because it’s a character, not just a clip. Instead of random one-off AI videos, it’s one consistent larger-than-life persona played completely straight, this impossibly cool guy who treats every street corner like a red carpet. That commitment to the bit is what people find funny and magnetic, and a recurring character gives them a reason to follow and come back, which random AI slop never does.

Here’s the playbook. Invent one strong, specific character with an instantly readable look and vibe, then put them in real-feeling everyday situations acting totally in-character. Keep the persona identical across every post so people recognize it in their feed, lean into one clear trait and crank it up, and let the humor come from how seriously the character takes itself. The win here isn’t a single viral video, it’s building an actual AI character people want to follow.
