# The AI Agent Index. The 2025 AI Agent Index documents the origins, design, capabilities, ecosystem, and safety features of **30 prominent AI agents** based on publicly available information and correspondence with developers. Chat agents maintain lower autonomy (Level 1-3), browser agents operate at Level 4-5 with limited intervention, and enterprise agents move from Level 1-2 in design to Level 3-5 when deployed. ### Transparency Gap. Of the 13 agents exhibiting frontier levels of autonomy, only 4 disclose any agentic safety evaluations. Agent development concentrates in the US (21/30) and China (5/30), with markedly different approaches to safety frameworks and compliance documentation. Autonomy levels differ systematically by agent category. ### Autonomy levels differ systematically by agent category. Chat agents maintain Level 1–3 autonomy with turn-based interaction. Each agent was annotated across 45 fields of information, organised into six categories, by seven subject-matter experts, using only publicly available information and developer correspondence.
