OpenAI announced on 2026‑04‑15 that it has updated its Agents SDK to include native sandbox execution and a model‑native harness. These additions allow developers to construct agents that run securely for extended periods, operate across multiple files, and integrate seamlessly with a variety of tools. The new sandbox provides isolated execution environments, reducing the risk of unintended side effects, while the model‑native harness streamlines the orchestration of agent tasks. For more details, see the official announcement at OpenAI).
