"scored 75.7% on ARC benchmark under standard compute conditions (87.5% using high compute)... key innovations: 1. program synthesis for task adaptation enables dynamically combining things learned during pre-training. 2. natural language program search, using chains of thought/ sophisticated search. 3. evaluator generates multiple solution/ determines most promising. 4. reusable building blocks. 5. deep learning-guided program search... challenge: high costs/ efficiency bottlenecks inherent in pushing to limits"
