Ethan Kam(@ethank_6):We've been testing the Decisions API for over a week. One of the coolest things was how many use cases the team found that just weren't practical before. We had to go back to every team and ask: what would you build with frontier intelligence at the cost of a tiny, tuned classifier? It was near-perfect at filtering low-quality pages and hit 88.8% AUPRC on page change classification. Prompt tuning helped push even more performance out of the model Excited to continue building!
