Decart

We are an AI research lab building Live AI models and an ultra-fast infrastructure to power them

[Decart @DecartAI]

Meet Lucy 2.5, our most advanced Live AI model yet.

Lucy edits videos in realtime, now with more capabilities and greater control.

See how it's being used across streaming, e-commerce, advertising, and more 🧵

What if an AI model could take back a harmful answer before it finishes it?

Diffusion language models can.

New Decart research accepted to #EMNLP2026 found harmful responses in just 9–21% of attacks, vs. 48–62% for comparable autoregressive models.

We turned that behavior into SRI Guard - detecting harmful generations with just 0.01–0.04% added latency.

Safety shouldn’t come at the cost of speed.

How much can we optimize?
Quite a lot, it turns out.

Decart Research is now live - a closer look at the work making our models faster, more efficient, and more capable.

Explore our publications, programs, and tools for the global research community - with more to come.

.@DecartAI founding member @AbermanKfir says world models could let robots train on real-world physics without needing to experience every scenario in the physical world:

"If LLMs can imitate the semantic world, world models can imitate the physical world."

"Imagine that you have a humanoid in a different environment. You'd have to collect this impossible type of data."

"But if you have world models that can simulate it with real physics, you'll be able to train these robots."

"That's the premise where we're at now. It hasn't been resolved yet."

Check out Anywear!

Great example of real products that are only possible with Live AI. This time, built for e-commerce!

[Kfir Aberman @AbermanKfir]

1/ We’re entering the era of agentic commerce, and we believe that world models are the missing engine.

Instead of browsing static product pages, agents will let you interact with products inside your own world before making decisions.

Today, @DecartAI we're releasing Anywear👇

[Sophia Yang @sophiamyang]

Okay third time is a charm & real-time & in a live app! App & code in 🧵.

Real-time video gen is getting better than I thought. Thanks @nickjohn @meh_agarwal for recommending @DecartAI Lucy!

[Justine Moore @venturetwins]

Damn this is so cool.

Finger frame your face and transform into different styles in real-time ✨

App made by @sophiamyang, powered by @DecartAI

[Denis Sibilev @thesibilev]

I’ve been building LucyLive — a real-time AI render plugin for @MaxonVFX Cinema 4D.
uses @DecartAI Lucy 2.5 through @fal

It follows your prompts and reference images while keeping C4D responsive.

I’d love to see your results.

[Vintage Investment Partners @Vintage_Inv]

Earlier this month we hosted the first-ever Vintage Enterprise AI Summit in Paris 🇫🇷✨

A huge thank you to our partners @UnframeAI, @alice_dot_io, @DecartAI, @HappyRobot, @USTglobal, and to @RaiseSummit , @amarmic, and @HenriDelahaye for bringing such an exceptional global AI community together in Paris. It was an honor to partner with you and build this alongside the broader RAISE week 🥂

This is Value+ in action: bringing the right founders, enterprises, investors, and LPs together, and turning those connections into lasting value.

Look out for the next edition! 👀

[Decart @DecartAI]

We’ve got the physics going too!

[Bob Doyle Media @bobdoylemedia]

The obvious use case is becoming a character on camera.

But the bigger deal is prompt-controlled transformation: characters, outfits, environments, objects, and visual effects changing while the camera is still live.

[Decart @DecartAI]

Great example!

Amazing to see your creativity with Lucy across every visual workflow - from cameras and TV shows to animation tools

[Hirokazu Yokohara @Yokohara_h]

シンプルな3Dモデルを操作してリアルタイムで女性へ変換
やっぱり動画生成はリアルタイムだと触っているだけで面白い
引き続きLucy 2.5 Realtimeを使用

[Decart @DecartAI]

@JonathanB0715 so cool!

[Decart @DecartAI]

@gcduncombe SO COOL!!! real ingenuity with that prompt🔥

[Decart @DecartAI]

Oh wow, this is creative 😅

You can also play with your imaginary boyfriend with Lucy 2.5. Apparently...

Share your best videos with us!

[Richelle🚢 @Richelle_Ji]

Played with my Lucy 2.5 date's hair, live.

and our joint arms.

🤯you can live stream an ai-generated subject/object.

more about how it works ⬇️

[Kfir Aberman @AbermanKfir]

1/ Today, we’re excited to introduce Lucy 2.5.

Lucy represents a paradigm shift in world models, not just in how generated worlds look, but in how we interact with them.

A thread on what makes it a paradigm shift 👇

[Decart @DecartAI]

@venturetwins Great videos!! Thank you for trying it out and for the detailed feedback! We're actually seeing very similar use cases in streaming and social as well. And yep, the lip sync is already much better, with even more improvements coming soon 💪

[Decart @DecartAI]

@ianmiles Hopefully in good ways! 😬

[Decart @DecartAI]

@nevertek_ It's based on DOS, our optimization stack!

[Decart @DecartAI]

@lostinlatencyX Yes! And with super low latency as well!😉

[Decart @DecartAI]

@jconorgrogan Amazing to hear! Finally an AI you can interact with
