Announcing Festivus: Physical AI for the Rest of Us
A catalog of robots, datasets, and policies — and a map of which ones actually work together. Open, checkable, and our first swing at the "Hugging Face for robotics" meme.
06 MAY 2026Pains & Opportunities in the "Hugging Face for Robotics" meme
What people actually mean when they say there should be a 'Hugging Face for robotics' — four open problems we keep hearing about, and an open call to builders.
29 APR 2026The Hardest Part of Shrinking a Robotics Model
Shrinking Pi0.5 by 2.9× on disk and 2.8× faster. The paper gives you the recipe; the pipeline tax is what makes it hard in production.
23 APR 2026My First Week at Haptic: Making a 3B Robot Policy Faster
A one-week POC: fine-tuning Pi0.5 to 100% on LIBERO-Spatial, then distilling its 10-step action head down to a single forward pass with SnapFlow.
