OpenAI Upgrades Agents SDK to Power Safer and Smarter AI Automation

[nihalsari]

OpenAI is doubling down on agentic AI by rolling out major updates to its Agents SDK, giving businesses more control over how AI-powered agents operate. One of the biggest additions is sandboxing—a feature that lets agents run in isolated environments, reducing risks while still allowing them to complete tasks using approved files and tools.

The update also introduces an “in-distribution harness,” which helps developers build and test more advanced agents capable of handling long, multi-step workflows. These improvements are designed to make it easier for companies to deploy reliable AI agents that can automate complex processes without compromising system security.

As competition heats up with players like Anthropic, OpenAI is positioning its SDK as a flexible foundation for enterprise AI automation. With more features and language support planned, the company is clearly aiming to make agent-based workflows a core part of how businesses use AI.

the in-distribution harness sounds like a step toward more reliable long-running agents, not just single prompts.
