Dyna-2: General Purpose Physical Agents with Hour-Long Autonomy — Jason Ma, Dyna Robotics

Latent Space 1 day ago 44

Dyna Robotics followed its Dyna-2 release with a physical robot agent, Dyna-2.1, and used a talk with Jason Ma to explain how its world-action model is used for long-horizon autonomy in real robotics. The robots reportedly achieved a 99.4% success rate folding restaurant napkins for 24 hours straight, including recovery after pulling over a stack. The focus shifts from training a large world-action model on video to deploying hour-long, task-executing physical agents built around custom hardware and agentic execution.

Is ‘Attention’ the Essence of Intelligence?

Quanta Magazine 2 days ago 47

Attention underpinned a shift in neural machine translation when Dzmitry Bahdanau and collaborators replaced fixed-size sentence representations with an attention mechanism that let models handle long sentences effectively, later scaled by Google’s transformer architecture. The transformer paper from 2017, “Attention Is All You Need,” reported state-of-the-art translation while using a fraction of the computation needed to train earlier models, and it has been cited more than 250,000 times. This changed model design by making attention central to modern large language models, enabling broad next-word language modeling that powers systems like ChatGPT.
