Open Deep Search: A Game-Changer in AI Research and Enterprise Solutions
Introduction
In a significant move for the AI landscape, researchers at the Sentient Foundation have unveiled the Open Deep Search (ODS), a new open-source framework that rivals proprietary AI search solutions like Perplexity and ChatGPT Search. With its ability to leverage large language models (LLMs) paired with advanced reasoning agents, ODS emerges as a formidable alternative for businesses seeking customizable, high-performance AI search tools.
The AI Search Landscape
The current market for AI-driven search solutions showcases products that seamlessly combine LLM capabilities with web search for up-to-the-minute information retrieval. However, a common flaw among these offerings is their proprietary nature, which often limits customization and flexibility for tailored applications. Himanshu Tyagi, co-founder of Sentient, pointed out that "most innovation in AI search has happened behind closed doors," emphasizing ODS’s goal to fill this gap by demonstrating that open-source systems can match or even exceed their closed-source counterparts in quality and speed.
Architecture of Open Deep Search (ODS)
ODS employs a modular architecture designed for easy integration with various LLMs, including both open-source models like DeepSeek-R1 and commercial ones like GPT-4o. At its core, ODS consists of two main components:
-
Open Search Tool
- This component reformulates user queries, broadening search coverage to extract diverse and relevant data from the web. Utilizing techniques like context extraction, re-ranking, and chunking, the tool ensures more contextual accuracy in responses. It also intelligently prioritizes credible sources when inconsistencies arise.
- Open Reasoning Agent
- This agent synthesizes user inquiries using the LLM and a suite of tools, including the Open Search Tool, to construct accurate replies. It offers two architectures:
- ODS-v1: This agent employs the ReAct agent framework alongside Chain-of-Thought (CoT) reasoning to iteratively refine answers.
- ODS-v2: Building upon CoT, this agent incorporates Chain-of-Code (CoC) and CodeAct, facilitating complex problem-solving through the generation and execution of code.

Performance and Practical Results
To validate ODS’s effectiveness, the team conducted extensive evaluations against popular closed-source competitors, including Perplexity AI and OpenAI’s GPT-4o Search Preview, by using benchmark tests designed for question-answering systems. ODS-v1 and ODS-v2 demonstrated impressive results, outpacing Perplexity’s flagship products. Notably, ODS-v2 consistently performed well against the GPT-4o Search Preview in more complex scenarios, showcasing its competitive edge.
Moreover, an interesting insight revealed the system’s efficiency, as ODS agents displayed strategic decision-making regarding additional searches based on initial result quality. For example, simpler queries prompted ODS-v2 to utilize fewer web searches, demonstrating its ability to optimize resource utilization.
Implications for the Enterprise
For businesses eager to adopt dependable AI search capabilities, ODS presents a unique opportunity. This framework provides a transparent and customizable alternative, allowing organizations to define their AI stack while avoiding vendor lock-in. The modular design of ODS ensures that companies can integrate various tools and models dynamically based on their specific needs.
Tyagi emphasized the significance of ODS’s design: "It selects which tools to use dynamically, based on descriptions provided in the prompt," offering versatility even with unfamiliar tools. However, he warned against bloated toolsets, advocating for careful design implementation.
Sentient has made ODS available on GitHub, signaling a commitment to ongoing innovation in the open-source AI search space.
What’s Next?
As organizations increasingly demand more robust AI solutions, ODS sets the stage for forthcoming advancements in the way AI interacts with and retrieves information. Its open-input and open-output strategy not only aims to compete with but also surpass existing solutions like Perplexity and ChatGPT. This positions ODS as a pivotal player that could reshape the landscape of AI-driven search capabilities.
Conclusion
The launch of Open Deep Search from the Sentient Foundation signifies a pivotal development in the quest for more adaptable and efficient AI search systems. As the pressure grows for enterprises to leverage AI for real-time information retrieval, ODS offers a compelling option that balances performance with customization.
