AgentDisCo: Open-source AI agent matches closed-source deep research
Multi-agent system disentangles exploration and exploitation for deeper research insights
AgentDisCo tackles the challenge of open-ended deep research by separating two often-conflated processes: information exploration and exploitation. Instead of a single monolithic module, it employs a critic agent that evaluates outlines and refines search queries, and a generator agent that retrieves updated results and revises outlines. This adversarial dynamic—where one agent pushes for new angles and the other synthesizes findings—iteratively produces a polished outline. The final content is passed to a report writer, while a meta-optimization harness allows the framework to discover new design strategies automatically using code-generation agents like Claude-Code and Codex to build a reusable policy bank.
Evaluated on DeepResearchBench, DeepConsult, and DeepResearchGym using Gemini-2.5-Pro, AgentDisCo achieves performance comparable to or surpassing top closed-source systems. Recognizing that existing benchmarks poorly reflect real-world needs, the team created GALA (General AI Life Assistants), which mines latent research interests from users' historical browsing behavior. An integrated rendering agent converts reports into visually rich posters. The end-to-end product, AutoResearch Your Interest, delivers personalized deep research recommendations directly from individual browsing histories—making advanced AI research tools accessible without manual configuration.
