Agent workbench gives each chat its own E2B machine, its builder says

A builder describes OpenAI's Agents API as a hosted Codex runtime that can connect to sandboxes such as E2B. They say their workbench gives each chat its own machine, starts from a custom template and automatically pauses between turns. It can also fork to try another approach from the same starting point and act on videos inside the sandbox, according to the builder, who shares a launch command, workbench code and documentation.
