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. 🌐 research.decart.ai

.@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."

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!

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

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👇

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. Free download: github.com/VantageInc/LucyLi… I’d love to see your results.

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! 👀

We’ve got the physics going too!

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.

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 👇

Realtime editing raises a very different challenge. A polished render can hide mistakes. A live stream cannot. I’d watch how Lucy handles hands, reflections, and sudden camera movement without breaking the illusion. That is where I’d judge the model :)

Virtual try-ons and live shopping just got a lot more powerful. @DecartAI ’s Lucy 2.5 can change outfits, backgrounds, or even entire scenes in realtime while someone is presenting a product. No more pre-recorded videos or clunky green screens. This feels like the next step toward truly interactive shopping experiences. The gap between seeing something online and feeling like you’re trying it on is shrinking fast.

For streamers and live creators, this is huge. Imagine audience members being able to influence what happens on screen in realtime changing scenes, adding effects, or triggering moments all powered by a live video model that actually understands the request. @DecartAI ’s Lucy 2.5 makes that kind of interactive streaming feel much closer to reality.
