DeepResearch: Tongyi DeepResearch, the Leading Open-Source DeepResearch Agent

🤗 HuggingFace ｜ ModelScope

We present Tongyi DeepResearch, an agentic large language model featuring 30.5 billion total parameters, with only 3.3 billion activated per token. Developed by Tongyi Lab, the model is specifically designed for long-horizon, deep information-seeking tasks. Tongyi DeepResearch demonstrates state-of-the-art performance across a range of agentic search benchmarks, including Humanity's Last Exam, BrowserComp, BrowserComp-ZH, WebWalkerQA,xbench-DeepSearch, FRAMES and SimpleQA.

Tongyi DeepResearch builds upon our previous work on the WebAgent project.

More details can be found in our 📰 Tech Blog.

• ⚙️ Fully automated synthetic data generation pipeline: We design a highly scalable data synthesis pipeline, which is fully automatic and empowers agentic pre-training, supervised fine-tuning, and reinforcement learning.
• 🔄 Large-scale continual pre-training on agentic data: Leveraging diverse, high-quality agentic interaction data to extend model capabilities, maintain freshness, and strengthen reasoning performance.
• 🔁 End-to-end reinforcement learning: We employ a strictly on-policy RL approach based on a customized Group Relative Policy Optimization framework, with token-level policy gradients, leave-one-out advantage estimation, and selective filtering of negative samples to stabilize training in a non‑stationary environment.
• 🤖 Agent Inference Paradigm Compatibility: At inference, Tongyi DeepResearch is compatible with two inference paradigms: ReAct, for rigorously evaluating the model's core intrinsic abilities, and an IterResearch-based 'Heavy' mode, which uses a test-time scaling strategy to unlock the model's maximum performance ceiling.

You can directly download the model by following the links below.

[2025/09/17]🔥 We have released Tongyi-DeepResearch-30B-A3B.

This guide provides instructions for setting up the environment and running inference scripts located in the inference folder.

• Recommended Python version: 3.10.0 (using other versions may cause dependency issues).
• It is strongly advised to create an isolated environment using conda or virtualenv.

Install the required dependencies:

• Create a folder named eval_data/ in the project root.
• Place your QA file in JSONL format inside this directory, e.g. eval_data/example.jsonl.
• Each line must be a JSON object that includes both of the following keys:
  {"question": "...","answer": "..."}
• A sample file is provided in the eval_data folder for reference.
• If you plan to use the file parser tool, prepend the file name to the question field and place the referenced file inside the eval_data/file_corpus/ directory.

• Open run_react_infer.sh and modify the following variables as instructed in the comments:
  • MODEL_PATH - path to the local or remote model weights.
  • DATASET - path to the evaluation set, e.g. example.
  • OUTPUT_PATH - path for saving the prediction results, e.g. ./outputs.
• Depending on the tools you enable (retrieval, calculator, web search, etc.), provide the required API_KEY, BASE_URL, or other credentials. Each key is explained inline in the bash script.

With these steps, you can fully prepare the environment, configure the dataset, and run the model. For more details, consult the inline comments in each script or open an issue.

We provide benchmark evaluation scripts for various datasets. Please refer to the evaluation scripts directory for more details.
