InfoMosaic-Bench: Evaluating Multi-Source Information Seeking in Tool-Augmented Agents

ICLR 2026poster

Information seeking is a fundamental requirement for humans. However, existing LLM agents rely heavily on open-web search, which exposes two fundamental weaknesses: online content is noisy and unreliable, and many real-world tasks require precise, domain-specific knowledge unavailable from the web.…

MCP-Persona: Benchmarking LLM Agents on Personalized MCP Tools and Tasks

ICML 2026poster

a transformative standard for connecting large language models (LLMs) with external data sources and tools, and has been rapidly adopted across personal applications and development platforms. However, existing benchmarks predominantly focus on generic information-seeking tools and fail to capture t…

Synthesizing Post-Training Data for LLMs through Multi-Agent Simulation

ACL 2025long

Post-training is essential for enabling large language models (LLMs) to follow human instructions. However, its effectiveness depends on high-quality instruction data, which is challenging to obtain in the real world due to privacy concerns, data scarcity, and high annotation costs. To fill this gap…

MADE: Malicious Agent Detection for Robust Multi-Agent Collaborative Perception

IROS 2024

Recently, multi-agent collaborative (MAC) perception has been proposed and outperformed the traditional single-agent perception in many applications, such as autonomous driving. However, MAC perception is more vulnerable to adversarial attacks than single-agent perception due to the information exch

Self-Alignment of Large Language Models via Monopolylogue-based Social Scene Simulation

ICML 2024spotlight

Aligning large language models (LLMs) with human values is imperative to mitigate potential adverse effects resulting from their misuse. Drawing from the sociological insight that acknowledging all parties' concerns is a key factor in shaping human values, this paper proposes a novel direction to al…
