Manually curated biomedical repositories -- spanning bioactivity, genomics, and chemistry -- are expensive to maintain, lag behind primary literature, and discard experimental context, obscuring nuances needed to assess data correctness and coverage. We show that PubMed itself can be autonomously and cost-effectively turned into structured datasets that are larger, more nuanced, and more accurate than the curated databases they replace. We present three coupled contributions: (1) an LLM-based entity-tagging pipeline, grounded in nine biomedical ontologies, that tags 4.5B entities across 19 categories in a 22.5M-paper, 2.5T-token PubMed corpus; (2) hybrid sparse-dense retrieval supporting entity-filtered semantic queries over the tagged corpus; and (3) Starling, a multi-agent deep research system that, given only a natural-language task description, designs precision- and recall-targeted retrieval filters, induces an extraction schema, and emits structured records with nuance-rich fields and supporting passages. Across six tasks -- blood-brain barrier permeability, oral bioavailability, acute toxicity (LD50), gene-disease associations, protein subcellular localization, and chemical reactions -- Starling produces ~6.3M records (91K-3M per task); several are, to our knowledge, the largest public datasets for their property. Frontier-model rejection of our extractions is 0.6-7.7% across tasks, far below error rates we measure on widely used curated counterparts (e.g., 16.5% on BBB_Martins, 7.3% on Bioavailability_Ma). Beyond scale and accuracy, the supporting passages carry nuance tabular databases discard -- e.g., oral bioavailability may depend on fed vs. fasted state. Together, the corpus, retrieval, and agent establish a foundation for AI-driven therapeutic design. Code and datasets: https://github.com/starling-labs/starling.
This paper introduces Starling, an end-to-end system for autonomously converting the PubMed literature (22.5M papers, 2.5T tokens) into structured, nuanced biomedical datasets. The system comprises three integrated components: (1) an LLM-based entity tagging pipeline covering 19 biomedical entity types grounded in nine ontologies, producing 4.5B entity tags; (2) a hybrid sparse-dense retrieval system enabling entity-filtered semantic queries; and (3) a multi-agent "deep research" system that autonomously designs extraction filters, induces schemas, and emits structured records with supporting passages.
The central claim is provocative and well-supported: automated extraction from primary literature can produce datasets that are simultaneously larger, more accurate, and more contextually rich than manually curated gold-standard databases. Across six tasks (BBB permeability, oral bioavailability, LD50, gene-disease associations, protein subcellular localization, chemical reactions), Starling produces ~6.3M records, with several representing the largest public datasets for their respective properties.
The methodology is carefully designed with multiple quality-control layers. The teacher-student distillation for entity tagging (gpt-oss-120b → gpt-oss-20b) with ontology-grounded normalization is well-motivated and executed. The probe-based retrieval strategy—where agents autonomously design precision- and recall-targeted filters—is an elegant solution to the corpus-scale extraction problem that distinguishes this from brute-force approaches.
The evaluation is thorough and multi-faceted:
A notable methodological concern is the reliance on frontier LLM judges (GPT-5.4, Claude Opus 4.7) for quality assessment, creating a potential circularity since extraction also uses LLMs. However, the human calibration study partially mitigates this. The comparison with baseline deep research systems (Table 4) is somewhat generous to Starling since baselines receive no per-row judging while Starling counts are post-filter, though the authors acknowledge this.
The potential impact is substantial across multiple dimensions:
For drug discovery and therapeutic design: The nuance captured by Starling—food state effects on bioavailability, dosing route effects on LD50, transport mechanism effects on BBB permeability—represents genuinely new training signal. The ANOVA analysis (Fig. 2) quantifying that dosing route explains 56% of within-molecule LD50 variance is a powerful argument that structure-only models hit a fundamental ceiling. Table 5's demonstration that TDC-trained models fail on active influx BBB molecules but Starling-augmented models succeed is directly actionable.
For dataset curation paradigm: If the quality claims hold, this paper challenges the dominant paradigm of manual expert curation, suggesting that autonomous extraction with quality filtering can be faster, cheaper ($0.001/record), and more accurate. This could democratize dataset creation for smaller labs.
For chemical reactions: The discovery of ~401K novel product SMILES not in any reference database is notable, though the 0.51× scale relative to ORD and patent-domain differences temper this.
This work arrives at an inflection point where LLM capabilities have made corpus-scale extraction feasible but existing biomedical AI still relies on static, context-stripped datasets. The paper directly addresses the increasingly recognized problem that benchmark datasets contain non-trivial error rates and that context-free labels limit model ceiling performance. The timing is excellent given the rapid scaling of AI-driven drug discovery.
Reproducibility: While code and datasets are released, the corpus licensing barrier is significant. The MCP server access plan is commendable but introduces dependency on the authors' infrastructure.
This is a high-impact systems paper that makes a convincing case for autonomous, literature-scale biomedical dataset construction. Its strongest contributions are the demonstrated accuracy advantage over manual curation and the quantified importance of contextual nuance. The work is likely to influence how the field approaches biomedical dataset creation and could accelerate context-aware therapeutic AI models.
