Paper: AI Research Preference Models Solve Compute Bottleneck

Problem: Generating ML ideas takes minutes, but testing them requires hours or days of GPU compute. Progress depends on selecting the right idea to run.
Solution: Introduces AI Research Preference Models (RPMs) to predict promising candidates without running all. Built from frozen LLMs in two variants:
- Inference-only: Reasons over plans, code, and history.
- Agentic: Additionally runs small-scale pilot experiments.
Results: Integrated into AIRA-dojo and evaluated on AIRS-Bench, the variants boost the average normalized score from 0.684 to 0.711 and 0.729 respectively.
