MedResearcher-R1 is a framework for generating and synthesizing domain-specific training data via knowledge-informed trajectory synthesis. It addresses the challenge of creating high-quality data for AI reasoning models in specialized domains, enabling the development of more capable reasoning agents that excel on complex benchmarks.

How It Works

The system comprises three integrated components:

1. Knowledge Graph Construction: Transforms domain knowledge into QA pairs with automated reasoning paths, using advanced sampling and obfuscation.
2. Trajectory Generation Pipeline: Synthesizes multi-turn reasoning trajectories from QA pairs, incorporating tool interactions, quality filtering, and LLM-powered optimization (MTG).
3. Evaluation Pipeline: Assesses model reasoning performance and validates data quality via interactive and batch evaluations. This end-to-end approach facilitates specialized, high-performance reasoning model development.

Quick Start & Requirements

• Installation: Requires Python >= 3.10. Setup via venv or conda, then pip install -r requirements.txt.
• Prerequisites: An OpenRouter API key is needed for the read tool, or manual LLM client modification. Environment variables must be configured. Links to demo video and feature guide are provided.

Highlighted Details

• Knowledge Graph: Features interactive D3.js visualization, 5 advanced sampling strategies, unified QA generation with concept obfuscation, automated reasoning path generation, and batch processing.
• Trajectory Generation: Employs an agent framework for multi-turn reasoning with tool integration, advanced quality filtering, and LLM-powered trajectory optimization (MTG).
• Evaluation: Supports interactive, step-by-step reasoning visualization and multi-worker batch dataset evaluation.
• Performance: Enabled MedResearcher-R1 model to achieve exceptional results on MedBrowseComp, GAIA, and XBench-DeepSearch benchmarks.
• Dataset: An open-sourced QA dataset (open_data.jsonl) with complex reasoning paths is available.
