Researchers have developed ProtAgent, a novel two-stage pipeline designed to improve protein annotation by using a compact model that learns through real tool interactions. This approach combines supervised fine-tuning for tool interface learning with reinforcement learning for policy improvement, assigning rewards at both the step and episode levels. In evaluations using real bioinformatics tools, ProtAgent-8B demonstrated a 61.00% success rate under the annotation-coverage metric, outperforming the DeepSeek-V3.2-Thinking 671B model and a previously strongest frontier system.
