Large language models (LLMs) have demonstrated remarkable potential in medical AI through their natural language understanding and reasoning capabilities. However, real clinical practice involves multi-stage, dynamically evolving decision-making where physicians continuously adjust pathways based on updated examination results—far more complex than single-turn question answering. Existing medical benchmarks focus on static scenarios, failing to evaluate LLMs in realistic clinical environments. We present MMedAgentBench, a comprehensive benchmark for evaluating LLM-based medical agents in multi-stage clinical decision-making. Unlike previous benchmarks, MMedAgentBench captures the temporal complexity of clinical workflows by simulating authentic patient journeys across multiple diagnostic and treatment stages. The benchmark comprises a high-quality dataset of over 150 de-identified clinical cases from tertiary hospitals, encompassing 500+ clinical stages, with each case meticulously structured into sequential stages and annotated by board-certified physicians. Our evaluation framework simultaneously assesses diagnostic accuracy and resource efficiency, requiring agents to plan examinations and control costs while navigating progressive information disclosure. This enables systematic evaluation of medical agents across dynamic decision-making, cost control, and multi-stage reasoning dimensions, providing a realistic testbed for advancing medical AI toward clinical deployment.

The ability of large language models (LLMs) to manage and acquire economic resources remains unclear. In this paper, we introduce Market-Bench, a comprehensive benchmark that evaluates the capabilities of LLMs in economically-relevant tasks through economic and trade competition. Specifically, we construct a configurable multi-agent supply chain economic model where LLMs act as retailer agents responsible for procuring and retailing merchandise. In the procurement stage, LLMs bid for limited inventory in budget-constrained auctions. In the retail stage, LLMs set retail prices, generate marketing slogans, and provide them to buyers through a role-based attention mechanism for purchase. Market-Bench logs complete trajectories of bids, prices, slogans, sales, and balance-sheet states, enabling automatic evaluation with economic, operational, and semantic metrics. Benchmarking on 20 open- and closed-source LLM agents reveals significant performance disparities and winner-take-most phenomenon, i.e., only a small subset of LLM retailers can consistently achieve capital appreciation, while many hover around the break-even point despite similar semantic matching scores. Market-Bench provides a reproducible testbed for studying how LLMs interact in competitive markets.

Recent advancements in open-source multi-modal large language models (MLLMs) have primarily focused on enhancing foundational capabilities, leaving a significant gap in human preference alignment. This paper introduces OmniAlign-V, a comprehensive dataset of 200K high-quality training samples featuring diverse images, complex questions, and varied response formats to improve MLLMs’ alignment with human preferences. We also present MM-AlignBench, a human-annotated benchmark specifically designed to evaluate MLLMs’ alignment with human values. Experimental results show that finetuning MLLMs with OmniAlign-V, using Supervised Fine-Tuning (SFT) or Direct Preference Optimization (DPO), significantly enhances human preference alignment while maintaining or enhancing performance on standard VQA benchmarks, preserving their fundamental capabilities.

With the rapid iteration of Multi-modality Large Language Models (MLLMs) and the evolving demands of the field, the number of benchmarks produced annually has surged into the hundreds. The rapid growth has inevitably led to significant redundancy among benchmarks. Therefore, it is crucial to take a step back and critically assess the current state of redundancy and propose targeted principles for constructing effective MLLM benchmarks. In this paper, we focus on redundancy from three key perspectives: 1) Redundancy of benchmark capability dimensions, 2) Redundancy in the number of test questions, and 3) Cross-benchmark redundancy within specific domains. Through the comprehensive analysis over hundreds of MLLMs’ performance across more than 20 benchmarks, we aim to quantitatively measure the level of redundancy lies in existing MLLM evaluations, provide valuable insights to guide the future development of MLLM benchmarks, and offer strategies to refine and address redundancy issues effectively.
