@xxunhuang Congrats!!

[Ethan @_ethan]

@PatrickToulme @MainzOnX Just registered, would love to meet up there!

[Ethan @_ethan]

@latkins @MangoSweet78 @TheEricHartford @QuixiAI Crazy how much has happened in a year!

[Decart @DecartAI]

What if video editing had a “volume knob”?

We are excited to share new research from @DecartAI and @TelAvivUni, accepted to #SIGGRAPH2026. We found directions within video models that enable smooth control over edit strength, from subtle changes to full transformations!

Check out our paper & blogpost 👇

We're hiring in SF! Autoregressive diffusion models have their own unique challenges and our opt team paves the way for new experiences like https://t.co/L25MnCZYSP

If this type of impact resonates with you, reach out to @hiba280700 with ref to your perf work!

I joined Decart to shape the AI industry and I’m hiring an engineer to join me. At most inference companies I could have gone to, I would just be improving Deepseek/Qwen and existing models. At Decart I shipped the first realtime diffusion model in the world to run on Trainium.

@roeschinc is it possible to get the md link updated to point to 13.2? https://t.co/Usunbwwv4x

[Ethan @_ethan]

stacked speaker lineup on perf ahead of GTC, come by if you're in SF!

[Decart @DecartAI]

Excited to have our chief scientist & co-founder Orian Leitersdorf speaking on realtime diffusion models — alongside @tedzadouri (FA4 first author) and @bfspector (ThunderKittens / @flappyairplanes) —
at a perf-focused evening, hosted by @Accel & @GPU_MODE.

Register now! https://t.co/Vi7gjyo8zR

@isidentical I've gotten more compliments on the GPU poor hat than any other swag!

[Ethan @_ethan]

Come chat with the team about realtime video at GTC!

[Decart @DecartAI]

We are hosting the first realtime AI event with @nvidia, @awscloud, @Deloitte, and @fal.

Meet the people building realtime AI and see what's shipping next from the lab.

🗓️ Tue, Mar 17 · 5–8 PM
📍 Fuze, San Jose

I am some dude at Decart. We don't have titles, and if we did they'd change more often than our GPU clusters.

That happens twice a week.

Our domain is the name of a french philosopher, if you spelled it wrong.

.ai.

Our entire budget is spent on the best scientists you can get. And DoorDash for dinner.

We don't have a marketing team. Well we do, but they are not allowed to use computers. You can reach them by standing under the balcony and yelling "Ido!!".

We don't have a balcony anymore. We are also on the 32nd floor.

We probably have a product somewhere, but who knows.

It's realtime for sure tho.

We are not hiring. If we did, we wouldn't tell you.

Members of technical staff preferred.

Drag, Drop and Try it live

That's just a small glimpse of what’s possible when AI runs in Realtime, powered by Lucy 2.0.

What else can you build?

[Ethan @_ethan]

@DecartAI Descartes on Decart... Decartception?

[Ethan @_ethan]

Excited for people to see what we've been cooking, the first real-time v2v model with reference image support running at these specs!

We're still just scratching the surface of these models and some prompts have surprised us (e.g. add a cat/spider and some light vfx). Try it out and let us know what you think! 🚀

[Decart @DecartAI]

Introducing Lucy 2.0: a World Editing Model running at 1080p, 30FPS in realtime.

Read the technical report, API access, and try the live demo 🧵

[Ethan @_ethan]

Now I'm only one character away from @ethan

@XHandles if I start publishing articles can we talk pls

[Ethan @_ethan]

@Dr_Gingerballs You think that OAI is paying an equivalent of $2-7/H100GPU-hr?

[Ethan @_ethan]

@cloneofsimo "Stochastic parrots" 😄

[Decart @DecartAI]

Meet Lucy Motion - an image-to-video model with precise control over motion.

Instead of struggling to describe movement in text and hoping the model gets it right, you draw a path from a subject to its destination. Lucy animates it exactly along that path.

[Ethan @_ethan]

When you have the world's best infra/optimization team and video research lab, you go beyond incremental perf gains to enabling new markets that were previously prohibitively slow/costly 🚀🚀🚀

[Decart @DecartAI]

Decart is pushing real-time visual intelligence forward.
Early access to Trainium3 helped us unlock 4× higher FPS and far more stable real-time video generation.

A new performance tier for our models.
