## Summary

OpenAI has released the Agents API as a public beta, marking a shift from simple question-answering to autonomous task execution. Unlike the Responses API, which requires developers to manage the agent loop, or the Agents SDK, which helps build agents, the Agents API allows OpenAI to manage the infrastructure, including model calls, tool usage, and context management. This enables agents to operate in a cloud-based workspace where they can handle files, execute code, and save intermediate results over long periods.

The system supports sub-agents, allowing a main agent to delegate specific tasks to specialized agents, similar to a human project team. This approach is designed for complex workflows, such as IT onboarding, where an agent can check systems, create accounts, and report status without constant human instruction. The release emphasizes that while the API automates execution, humans must still define authority, approval boundaries, and responsibility for errors.

The article notes that this does not end the era of asking AI questions but changes the focus from crafting prompts to delegating work. It highlights the need for new management skills to oversee AI agents, ensuring they operate within defined limits. The API is currently in public beta, with specifications subject to change.

## Key points

- OpenAI released the Agents API as a public beta on September 10, 2026.
- The API manages the agent harness, including tool usage and context, in the cloud.
- Agents can use workspaces to handle files, execute code, and delegate tasks to sub-agents.

## Why it matters

This shifts AI usage from interactive Q&A to autonomous task completion, requiring developers to manage agent authority and workflows rather than just prompts. It enables complex, multi-step business processes to run with less human intervention.
