Artificial intelligence startup Decart continues to stretch the boundaries of what’s possible with the release of its latest live video model, Lucy 2.5, introducing real-time streaming visual effects capabilities for the first time.

The startup claims that Lucy 2.5 is unique in its ability to generate AI VFX continuously, on the fly, and embed them into live videos as they’re being created. For the first time, media production firms and independent creators alike will be able to generate realistic fireballs, have characters breathe out smoke, burst into flames or even inflate and explode in a gory mess at the flick of a prompt.

What it’s promising is Hollywood movie-style effects, limited only by the imagination, and without the need for post-production processing.

Lucy 2.5 has the potential to unlock a real jump in creativity, but its usefulness doesn’t stop there. The model’s mastery of complex physics and intricate visual detail also provides a stronger footing for Decart to fulfil its broader ambitions in the physical AI arena. Lucy 2.5 doesn’t just deliver cinematic flair, but serves as a dual-purpose engine that can enable greater accuracy in its world model simulations used for robotics training.

Decart has enhanced the Lucy model significantly since the release of version 2 just five months ago. The biggest change is the addition of realistic visual effects, with users able to insert explosions, fire, tsunamis and completely alter the appearance of on-screen characters, such as by giving them the appearance of a melting chocolate bar.

Creatives will be able to prompt special effects to their heart’s content, and they’ll look far more realistic than the effects created by earlier models, thanks to its improved physics engine and prompt adherence.

There’s also more precision. Decart says users are being given finer control over exactly how AI-generated elements are placed and behave when integrated into a live video. They will also be able to erase unwanted objects and characters in an instant, without any noticeable artefacts that give away the fact it has been edited. These capabilities all add up to a far more realistic-looking end result, and they’re already available through the Decart API.

Advertising and marketing is an obvious target for Decart, with Lucy 2.5 enabling these types of users to create personalized versions of promotional clips in real time.
