reasoning.<br \/>\nWhat is unique:<\/p>\n<p>\u2022 Context + integrity verification while building the research plan (catches context slips early)<br \/>\n\u2022 Pre-run and post-run checks around tool execution (an analysis can run without errors and still be wrong)<br \/>\n\u2022 Study relevance + evidence-strength screening for literature (not just retrieval)<br \/>\n\u2022 Multi-round consensus that reconciles tool outputs, literature, and the LLM, with calibrated abstention when evidence is insufficient<br \/>\n\u2022 A rich tool space with single-cell and bulk transcriptomics FMs, genetic dependency maps, protein and tissue networks, pathway and ontology resources, and interpretable ML models<\/p>\n<p>3\ufe0f\u20e3 We evaluate Medea across 5,679 analyses in three open-ended domains:<\/p>\n<p>\ud83d\udd39 Target identification across cell type contexts<br \/>\n\ud83d\udd39 Synthetic lethality reasoning in cancer cell lines<br \/>\n\ud83d\udd39 Immunotherapy response prediction from patient transcriptomes<\/p>\n<p>4\ufe0f\u20e3 Target discovery fails when biology is averaged. Medea reasons at cell-type resolution, integrating:<\/p>\n<p>\u2022 single-cell atlases<br \/>\n\u2022 disease genetics<br \/>\n\u2022 drug evidence<\/p>\n<p>5\ufe0f\u20e3\u00a0Synthetic lethality asks a subtle question: Do two gene perturbations together reduce viability more than expected from either alone?<\/p>\n<p>Medea treats this as an evidence synthesis task, combining:<\/p>\n<p>\u2022 CRISPR dependency data<br \/>\n\u2022 pathway context<br \/>\n\u2022 literature support<\/p>\n<p>And it abstains when evidence is weak.<\/p>\n<p>6\ufe0f\u20e3 Across seven cancer cell lines, Medea outperforms LLMs in identifying true synthetic lethal interactions.<\/p>\n<p>Medea not only predicts more positives but also corrects LLM errors and avoids confident false claims.<\/p>\n<p>7\ufe0f\u20e3 Immunotherapy response prediction from personal transcriptomes<\/p>\n<p>Predicting immunotherapy response requires reasoning over:<\/p>\n<p>\u2022 tumor transcriptomes<br \/>\n\u2022 immune programs<br \/>\n\u2022 clinical context<\/p>\n<p>8\ufe0f\u20e3 Medea works where heuristics fail. Across TMB-high\/low and inflamed\/non-inflamed tumors, Medea:<\/p>\n<p>\u2022 outperforms LLMs<br \/>\n\u2022 rescues errors from ML models<br \/>\n\u2022 adapts reasoning to subgroup
