Research on AI agents traces back to the 1990s while researcher Andrew Ng spread the term agentic to a wider audience in 2024. The Financial Times compared the autonomy of these systems to self-driving car classifications where most applications reach level 2 or level 3 status.
Prominent examples include Devin AI, AutoGPT, and SIMA which were released before 2025 alongside OpenAI Operator and ChatGPT Deep Research released since then. Hugging Face published Open Deep Research as an open source version in February 2025 while Galileo AI created a leadership board for agents ranking performance based on underlying LLMs.
Ken Huang proposed an architecture consisting of seven interconnected layers that provide foundation models data operations software frameworks technical foundations safety assessment security compliance and user interface respectively. Layer 1 provides core engines while Layer 7 represents the interface with real-world applications and users.
New York Magazine described software development as the most definitive use case in August 2025 while The Information noted AI coding agents and customer support as primary business use cases by October 2025. Government bodies including the Internal Revenue Service and Staffordshire Police have deployed or announced deployment of these systems at local and national levels.
Financial stability bodies warned that complex autonomous systems could become channels for systemic risk after a 2025 forum found 44% of experts judged them the most likely current source of AI-related financial risk. Concerns include liability issues increased cybercrime risks ethical challenges lack of guaranteed repeatability algorithmic bias and potential for infinite loops creating operational failures.
