Today OpenAI announced o3, its next-gen reasoning model. We've worked with OpenAI to test it on ARC-AGI, and we believe it represents a significant breakthrough in getting AI to adapt to novel tasks. It scores 75.7% on the semi-private eval in low-compute mode (for $20 per task

New working paper! We study 100k+ property tax appeals hearings, documenting gender biases in hearing outcomes. We then leverage 2.7 years of hearing audio recordings to try to understand how these arise. Conclusion? Implicit bias. arxiv.org/abs/2412.12610
