Agentic AI has gained significant attention, but current research lacks standardization, making fair comparisons difficult. In this work, we conduct a systematic study on key design choices in agent frameworks using the GAIA and BrowseComp benchmarks. We introduce a robust evaluation protocol to ensure reproducibility and identify crucial components for effective agents. Based on our findings, we develop and open-source OAgents, a modular foundation agent framework that achieves state-of-the-art performance among open-source projects, promoting future research in Agentic AI.
To get started, follow the steps below:
Run the following command to install the required dependencies from the requirements.txt file:
pip install -r ./oagents/example/oagents_deep_research/requirements.txtcd oagents
pip install -e ./.[dev]We provide a template file named .env_template for your convenience. You can copy this file and rename it to .env, then fill in your actual API keys and service addresses. For example:
cp .env_template .envThen edit the .env file with your credentials.
The agent uses the following external services for web search and content crawling. Please configure the corresponding API keys:
-
Search Engine: SerpApi
Used for performing web searches. Get your API key from SerpApi and set it as:SERP_API_KEY=<your-serp-api-key> -
Web Crawler: Jina AI Reader
Used for accessing and parsing web content. Sign up at Jina AI to obtain an API key and set it as:JINA_API_KEY=<your-jina-api-key>
Download the GAIA dataset and place it under the following directory:
./oagents/example/oagents_deep_research/data/gaia
The expected directory structure is as follows:
βββ data
β βββ gaia
β βββ test
β βββ validation
You're now all set to run on GAIA! First, go to main part of GAIA evaluation.
cd ./oagents/example/oagents_deep_researchSimply execute the run_gaia.py script, like so:
python run_gaia.py --model_id gpt-4.1 --model_id_search gpt-4.1 --run_name gpt-4.1-gaiaIf you'd like to use different questions or datasets, you can refer to the run_gaia.py script for guidance and make the necessary adjustments.
To simplify the agent exploration process in the TTS algorithm, we have removed the nested ToolCalling agent structure. Instead, the CodeAgent now directly interfaces with various tools, eliminating intermediate layers while maintaining full functionality. This architectural change reduces computational overhead and improves execution efficiency.

Our implementation has been adapted from the official repository:
Their thoughtful design and clear code structure greatly facilitated our exploration and experimentation.
In the context of our framework OAgents, we have made several modifications to the original implementation, including but not limited to:
- π Architecture adjustments: We restructured key components such as the memory module and planning system to better align with our experimental goals. Specifically, we implemented and evaluated multiple memory architectures (e.g., short-term memory, long-term memory, and etc.) and tested various agent workflows to assess their impact on task performance and learning efficiency.
- π οΈ Tools optimization: We enhanced the agentβs toolset by refining the search agent and introducing improved search and data processing capabilities. These updates aim to significantly boost the agent's ability to acquire, interpret, and utilize external knowledge during task execution.
- β±οΈ Test-time scaling strategies: To further reduce inference errors and improve robustness, we incorporated test-time scaling techniques, such as repeated reasoning, majority voting, and consistency filtering. These methods were used to refine decision-making during deployment and enhance overall reliability.
These changes were made with the goal of conducting a more rigorous and reproducible empirical analysis of agent-based learning systems. We acknowledge the importance of building upon existing work and hope that our contributions can further enrich the community's understanding of agent framework.
