Sentient, a San Francisco-based AI lab valued at $1.2 billion, unveiled Open Deep Search (ODS), an open-source AI search framework, claiming it surpasses closed-source rivals like OpenAI's GPT-4o Search Preview. Sponsored by Peter Thiel's Founder's Fund, Sentient positions its work as the U.S. response to China's DeepSeek. According to their testing, ODS achieved 75.3% accuracy on FRAMES, significantly outpacing GPT-4o and Perplexity Sonar Reasoning Pro. Sentient's approach excludes 'ground truth' sources such as Wikipedia to ensure authentic evaluations, relying instead on its retrieval systems. The framework utilizes an 'agentic approach' to refine queries and enhance information retrieval. Sentient's models are seen as a challenge to the dominance of closed AI systems. As 2025 shapes up to be the year of AI agents, Sentient's announcement underscores a pivotal moment for open-source AI technologies. Experts suggest that the release of such technologies cannot be contained once made public, marking a significant philosophical shift in AI development.
