Temporal Sandbox Orchestration Harness: Durable Execution for AI Agents — Survive Infrastructure Failures, Fork Running Agents Onto Different Sandbox Providers

Temporal Blog·medium signal

Temporal partnered with OpenAI to run sandbox agents as durable Temporal workflows with session management, backend switching, and the ability to fork a running agent onto a completely different sandbox provider mid-execution. Workflows persist indefinitely and survive infrastructure failures. Key insight: agents need durable context that outlives any single process — Temporal provides this without changing how you write the agent code.
