OpenAI's sandboxed terminal agent that batches tool calls to keep long tasks cheap

Codex CLI drives a sandboxed workspace from the shell, planning edits, executing commands and running tests in one batched loop instead of one action per turn. On the Artificial Analysis index (GPT-6.1 Sol config) it finishes coding tasks in about 15 minutes at $1.50 per task, with prompt caching doing most of the cost saving.
