A guessing game for everyone. As you see, I am super excited to be on two panels on Dec 6 and Dec 7 at @NeurIPSConf. Come see them! But the real questions are: Which picture of mine was taken in 2010 , and Which one was taken in 2020 😜? All bets are welcome! Happy to grab

Shocked to see that the Veo/Google model (and others) are quite a bit worse!
Runway Gen-4.5 represents significant advancements in both pre-training data efficiency and post-training techniques for video models and serves as our new foundation model for world modeling. Gen-4.5 scored 1,247 Elo points in the Artificial Analysis Text to Video leaderboard,

3/8 How it works 👉 Tokenization: turns different data types into a shared “language” 👉 Masked modeling: hides pieces of data during training so the model learns to reconstruct and capture cross-modal and intra-modal relationships.
