AI co-scientist workflows: LLM choice dominates protein characterization accuracy

By PulseAugur Editorial · [2 sources] ·

A new arXiv paper explores the trade-offs between flexibility and reasoning in AI co-scientist workflows for protein characterization. The study found that the choice of large language model (LLM) significantly impacted prediction quality, with Opus models achieving 92-94% accuracy compared to o4-mini at 40-50%. Proximal Policy Optimization (PPO) policies offered near-frontier accuracy (88%) with zero token cost and perfect consistency but lacked a reasoning trace. For routine tasks, deterministic policies are recommended for accuracy and reproducibility, while LLMs are better suited for open-ended discovery. AI

IMPACT LLM choice is a critical factor for accuracy in scientific AI workflows, with deterministic policies offering a cost-effective alternative for routine tasks.
