OpenSeeker: Democratizing Frontier Search Agents by Fully Open-Sourcing Training Data

📰 News

• 2026.03.20 📣 We’ve released a new batch of higher-quality, more challenging data. For details, please contact us at yr991129@sjtu.edu.cn.
• 2026.03.17 🚀 We open-sourced OpenSeeker-v1 (all data and models). Using 11.7K training examples, we fine-tuned Qwen3-30B-A3B-Thinking-2507 and achieved scores of 48.4 on BrowseComp-ZH, 29.5 on BrowseComp, 74.0 on xbench-DeepSearch, and 59.4 on WideSearch.

Overview

OpenSeeker is an open-source search agent system that democratizes access to frontier search capabilities by fully open-sourcing its training data. This project enables researchers and developers to build, evaluate, and deploy advanced search agents for complex information-seeking tasks.

---

🌟 Key Achievement

OpenSeeker represents the first work by a purely academic team to achieve state-of-the-art performance on frontier search benchmarks while simultaneously open-sourcing the full training data.

Quick Start

Installation

Clone the repository and set up the environment:

# Clone repository
git clone https://github.com/rui-ye/OpenSeeker.git
cd OpenSeeker

# Create conda environment
conda create --name openseeker python=3.10
conda activate openseeker
pip install -r requirements.txt

Model Setup

Download and deploy the OpenSeeker model:

# 1. Install git-xet (required for downloading the model)
brew install git-xet
git xet install

# 2. Clone the OpenSeeker model repository
git clone https://huggingface.co/OpenSeeker/OpenSeeker-v1-30B-SFT

# 3. Update MODEL_PATH in run_openseeker.sh to point to the downloaded model directory
# Edit run_openseeker.sh and set MODEL_PATH="/path/to/OpenSeeker-v1-30B-SFT"

# 4. Deploy the model server
bash run_openseeker.sh

Configuration

# Edit setup_env.sh with your API endpoints and keys
source setup_env.sh

Usage

Generate answers and evaluate results:

# Generate answers for your dataset
python eval/generate_answer.py \
    --dataset_path /path/to/your/dataset.jsonl \
    --out_dir /path/to/output/directory

# Evaluate the generated results
python eval/eval.py \
    --data_path /path/to/output/directory/result_tool200.jsonl \
    --max_workers 20
