three years ago, DiT replaced the legacy unet with a transformer-based denoising backbone. we knew the bulky VAEs would be the next to go -- we just waited until we could do it right. today, we introduce Representation Autoencoders (RAE). >> Retire VAEs. Use RAEs. 👇(1/n)

Someone posted this on Reddit the other day. It tells you everything about American healthcare in 2025. Look at the right column. Prescription refills, urgent care needs, chronic conditions, cold symptoms, minor injuries. The poster says: don't call 911 for these, and that's 100%

🔥Veo 3 has emergent zero-shot learning and reasoning capabilities! This multitalented model can do a huge range of interesting tasks. It understands physical properties, can manipulate objects, and can even reason. Check out more examples in this thread!
Veo is a more general reasoner than you might think. Check out this super cool paper on "Video models are zero-shot learners and reasoners" from my colleagues at @GoogleDeepMind.

Dreamer 4 takes world models to a new level - training multi-task agents fully in imagination while never touching the real environment. Powered by a novel shortcut forcing method, it delivers lightning-fast, accurate predictions and crushes benchmarks, beating OpenAI’s VPT

Hard to overstate how big of a deal this is: 1. Train a video model on Minecraft 2. Train agent on video model WITHOUT ACTUALLY PLAYING THE GAME 3. The agent gets better at Minecraft Learn in imagination, act in reality 🤯 ∴ define a great env -> learn anything More

complex robotics self-learning on video generation will go *very* far. It seems to have very nice scaling properties. Expect the most general robots in 1-2 years to be pretrained on a lot of video and text, and then train robotics skills within generated worlds

Clean and well-executed new work from @danijarh @wilson1yan , and it's cool to see shortcut models working at scale! The exciting finding is that you can train the world model largely on *unlabelled* videos, and only need a small action-anchoring dataset.
