If models think in shapes, our tools should too. Our latest research: Block-Sparse Featurizers (BSFs), a new way to find concepts in model activations - using multidimensional “blocks” instead of single directions. (1/9)

The broader point: a featurizer is a hypothesis about how a model’s representations are structured. We think this is a step forward in tools reflecting that. Paper, code, and full post: goodfire.ai/research/bsf-v…

Neural networks might speak English, but they think in shapes. Understanding their rich *neural geometry* is key to understanding how they work – and to debugging and controlling them with precision. Starting today, we’re releasing a series of posts on this research agenda. 🧵

Honored to be featured in @ucsantabarbara newsletter with my research and an international award For years I wasn’t sure my research counted as physics. It apparently does! The questions define us. Read the questions that shaped my career! news.ucsb.edu/2026/022632/ne…
How are scientists mapping consciousness? Could geometry hold the key? Claire Isabel Webb, director of the Future Humans program at the @berggruenInst, asks @NinaMiolane of the UCSB Geometric Intelligence Lab. Watch the full episode here: na2.hubs.ly/H068tRX0
