(1/3) Bigger is better, but we couldn't handle it until now! Our lab unveils xT & S2, turning the tide on gigapixel image processing with smaller, scalable models. Efficiency meets precision, reshaping how we model high-frequency images...

(2/3) xT lets you model gigapixel images by introducing nested tokenization and the fusion of distinct vision and language models. xT gets you higher accuracy, less memory usage per pixel, and higher throughput while preserving local and global context: ai-climate.berkeley.edu/xt-website/

(3/3) S2 demonstrates that smaller models can closely approximate the features of larger vision models, challenging the necessity for scale in tackling complex images. Pre-training smaller, multi-scale models with S2 can beat large models on the same task: github.com/bfshi/scaling_…

Our new VH benchmark shows existing models (including GPTo) fail on simple visual retrieval questions when placed in context with multiple distractors; in contrast, our retrieval augmented 7B MIRAGE model can find the signal from the noise and answer the question...

Super excited to announce our work on 'real-'world models! Our Conditional Diffusion Transformer (CDiT) has complexity linear in the number of context frames, can plan and navigate in known worlds, and can imagine outcomes in new settings!

What happens when vision🤝 robotics meet? Happy to share our new work on Pretraining Robotic Foundational Models!🔥 ARM4R is an Autoregressive Robotic Model that leverages low-level 4D Representations learned from human video data to yield a better robotic model. Berkeley AI Research😊

Super excited about our new work on pretrained 4-D robotic foundation models. LLMs learned with 4-D representations on egocentric datasets transfer well to real world tasks!
