🔬 Open Deep Research - Enhanced with Gensee Search

Fork Notice: This is an enhanced version of LangChain's Open Deep Research, integrated with Gensee Search for improved search capabilities and reasoning. Check LangChain's repo to learn more about how it's built.

🚀 What's Different in This Version

• 🔍 Gensee Search Integration: Replaced Tavily with Gensee Search for enhanced search quality and AI application optimization
• 🧠 Improved Reasoning: Enhanced agent prompts to encourage more thorough search and reasoning processes
• 🛠️ Easy Integration: Demonstrates simple integration of Gensee's testing and optimization tools for GenAI applications

🚀 Quickstart

1. Clone the repository and activate a virtual environment:

git clone https://github.com/GenseeAI/open_deep_research.git
cd open_deep_research
uv venv --python=3.12
source .venv/bin/activate  # On Windows: .venv\Scripts\activate

2. Install dependencies:

uv sync
# or
uv pip install -r pyproject.toml

3. Set up your .env file to customize the environment variables (for model selection, search tools, and other configuration settings):

Get FREE access to Gensee Search from https://platform.gensee.ai/

cp .env.example .env
# GENSEE_API_KEY=your_api_key_here

4. Launch agent with the LangGraph server locally:

# Install dependencies and start the LangGraph server
uvx --refresh --from "langgraph-cli[inmem]" --with-editable . --python 3.11 langgraph dev --allow-blocking

This will open the LangGraph Studio UI in your browser.

⚙️ Configurations

See the fields in the run_evaluate.py to config the model usage and other agent behaviors.

📊 Evaluation

Open Deep Research is configured for evaluation with Deep Research Bench. This benchmark has 100 PhD-level research tasks (50 English, 50 Chinese), crafted by domain experts across 22 fields (e.g., Science & Tech, Business & Finance) to mirror real-world deep-research needs. It has 2 evaluation metrics, but the leaderboard is based on the RACE score. This uses LLM-as-a-judge (Gemini) to evaluate research reports against a golden set of reports compiled by experts across a set of metrics.

Usage

Warning: Running across the 100 examples can cost ~$20-$100 depending on the model selection.

# Run comprehensive evaluation on LangSmith datasets
python tests/run_evaluate.py

This will provide a link to a LangSmith experiment, which will have a name YOUR_EXPERIMENT_NAME. Once this is done, extract the results to a JSONL file that can be submitted to the Deep Research Bench.

python tests/extract_langsmith_data.py --project-name "YOUR_EXPERIMENT_NAME" --model-name "you-model-name" --dataset-name "deep_research_bench"

This creates tests/expt_results/deep_research_bench_model-name.jsonl with the required format. Move the generated JSONL file to a local clone of the Deep Research Bench repository and follow their Quick Start guide for evaluation submission.
