BioStudyBench: Evaluating Agents on Post-Cutoff Biomedical Studies

BioStudyBench is a new benchmark that tests AI agents on 25 long‑horizon analysis tasks derived from biomedical studies published between July and September 2026, after the models’ knowledge cutoffs. Each task gives the agent a neutral research question but no data files, requiring it to locate and download relevant public data, search literature using tools limited to pre‑cutoff records, and perform data analysis to report findings. The benchmark shows that providing data and tools improves model performance by an average of 47 percentage points, with closed‑weight models outperforming open‑weight ones (best open‑weight 81.3% vs. best closed‑weight 94.7%).

ClinAgent: A ReAct-Based Agent for Conversational Access to Clinical Trial Information

ClinAgent is a conversational system that uses a ReAct-based LLM agent to retrieve and synthesize clinical trial information from multiple sources such as ClinicalTrials.gov, PubMed, and a local dataset. The agent iteratively reasons over user queries, selects appropriate tools, and refines its actions to provide grounded, up-to-date responses in natural language across multi-turn interactions. Evaluation across three phases shows that DeepSeek (thinking mode) excels in planning quality while Gemini 3.0 Flash delivers the highest overall performance and expert ratings, demonstrating the promise of agentic AI for improving clinical trial data access.

Tasks over Application Manuals: Revealing Gaps in Long-Horizon Procedural Reasoning for Language Models

The paper introduces Tasks over Application Manuals (TAM), a benchmark designed to test long‑horizon procedural reasoning in large language models. TAM uses real‑world tasks from ICD‑10‑CM clinical coding and U.S. federal sentencing, requiring models to follow extensive, rule‑based manuals and perform interdependent steps to produce exact answers. Experiments with GPT‑5 and various prompting strategies show very low exact‑match accuracy—1% for coding and 15.5% for sentencing—highlighting a gap between current benchmarks and the ability to reliably follow complex procedures.

Foundation Agents Meet Agentic Deep Research: Evidence-Grounded Clinical Code Forecasting

The paper introduces ICD-Deepresearch, a workflow that combines foundation models for electronic health records (EHR) and language models with medical search and ICD dictionaries to forecast future ICD codes for upcoming clinical encounters. It evaluates candidate code transitions by linking patient evidence, external clinical relations, and exact code semantics within a fixed top‑K budget, using SparseEHR for initial priors, GPT‑5 for complementary forecasts, and a final selection step that validates, deduplicates, and ranks candidates. The method achieves patient‑averaged precision/recall of 24.60/35.09% on MIMIC‑III and 25.14/48.32% on MIMIC‑IV, with physicians rating 51–68% of its retrieved documents as useful, outperforming standalone GPT‑5 web search and Medical Deep Research.
